Release Notes for SD-WAN Release 17.1.x

New and Modified Configuration Commands

New and Modified Operational Commands

Hardware Caveats

The following are known behaviors of the Viptela hardware

• On vEdge 1000 routers, support for USB controllers is disabled by default. To attach an LTE USB dongle to a vEdge 1000 router, first attach the dongle, and then enable support for USB controllers on the vEdge router, by adding the system usb-controller command to the configuration. When you enter this command in the configuration, the router immediately reboots. Then, when the router comes back up, continue with the router configuration. Also for vEdge 1000 routers, if you plug in an LTE USB dongle after you have enabled the USB controller, or if you hot swap an LTE USB dongle after you have enabled the USB controller, you must reboot the router in order for the USB dongle to be recognized. For information about enabling the USB controller, see USB Dongle for Cellular Connection.

• For vEdge 2000 routers, if you change the PIM type from a 1-Gigabit Ethernet to a 10-Gigabit Ethernet PIM, or vice versa, possibly as part of an RMA process, follow these steps:
  1. Delete the configuration for the old PIM (the PIM you are returning as part of the RMA process).
  2. Remove the old PIM, and return it as part of the RMA process.
  3. Insert the new PIM (the PIM you received as part of the RMA process).
  4. Reboot the vEdge 2000 router.
  5. Configure the interfaces for the new PIM.

Software Caveats

The following are known behaviors of the Viptela software:

Cellular Interfaces

• The vEdge 100wm router United States certification allows operation only on non-DFS channels.

• When you are configuring primary and last-resort cellular interfaces with high control hello interval and tolerance values, note the following caveats:
  
  1. When you configure two interfaces, one as the primary interface and the other as the last-resort interface, and when you configure a high control hello interval or tolerance values on the last-resort interface (using the hello-interval and hello-tolerance commands, respectively, the OMP state indicates init-in-gr even though it shows that the control connections and BFD are both Up. This issue was resolved in Release 16.2.3. However, the following caveats exist:
  — You can configure only one interface with a high hello interval and tolerance value. This interface can be either the primary or the last-resort interface.
  — In certain cases, such as when you reboot the router or when you issue shutdown and no shutdown commands on the interfaces, the control connections might take longer than expected to establish. In this case, it is recommended that you issue the request port-hop command for the desired color. You can also choose to wait for the vEdge router to initiate an implicit port-hop operation. The request port-hop command or the implicit port hop initiates the control connection on a new port. When the new connection is established, the stale entry is flushed from the vSmart controllers.
  
  2. If the primary interface is Up, as indicated by the presence of a control connection and a BFD session, and if you configure a last-resort interface with higher values of hello interval and tolerance than the primary interface, if you issue a shutdown command, followed by a no shutdown command on the last-resort interface, the last-resort interface comes up and continuously tries to establish control connections. Several minutes can elapse before the operational status of the last-resort interfaces changes to Down. If this situation occurs, it is recommended that you issue a request port-hop command for the desired color.
  
  3. If you have configured a primary interface and a last-resort interface that has higher hello interval and tolerance values than the primary interface, and if the last-resort interface has control connections to two vSmart controllers, if you issue a shutdown command, followed by a no shutdown command on the last-resort interface, a control connection comes up within a reasonable amount of time with only one of the vSmart controllers. The control connection with the second vSmart controller might not come up until the timer value configured in the hello tolerance has passed. If this situation occurs, it is recommended that you issue a request port-hop command for the desired color.

• For cellular interface profile, the profile number can be 0 through 15. Profile number 16 is reserved, and you cannot modify it.

Configuration

• When you issue the request reset configuration command on a vEdge Cloud router, a vManage NMS, or a vSmart controller, the software pointer to the device's certificate might be cleared even though the certificate itself is not deleted. When the device reboots and comes back up, installation of a new certificate fails, because the certificate is already present. To recover from this situation, issue the request software reset command.

Control and BFD Connections

• When a vBond orchestrator, vManage NMS, or vSmart controller goes down for any reason and the vEdge routers remain up, when the controller device comes back up, the connection between it and the vEdge router might shut down and restart, and in some cases the BFD sessions on the vEdge router might shut down and restart. This behavior occurs because of port hopping: When one device loses its control connection to another device, it port hops to another port in an attempt to reestablish the connection. For more information, see the Firewall Ports for Viptela Deployments article. Two examples illustrate when this might occur:
  • When a vBond orchestrator goes down for any reason, the vManage NMS might take down all connections to the vEdge routers. The sequence of events that occurs is as follows: When the vBond orchestrator crashes, the vManage NMS might lose or close all its control connections. The vManage NMS then port hops, to try to establish connections to the vSmart controllers on a different port. This port hopping on the vManage NMS shuts down and then restarts all its control connections, including those to the vEdge routers.
  • All control sessions on all vSmart controllers go down, and BFD sessions on the vEdge routers remain up. When any one of the vSmart controllers comes back up, the BFD sessions on the routers go down and then come back up because the vEdge routers have already port hopped to a different port in an attempt to reconnect to the vSmart controllers.

• When a vEdge router running Release 16.2 or later is behind a symmetric NAT device, it can establish BFD sessions with remote vEdge routers only if the remote routers are running Release 16.2 or later. These routers cannot establish BFD sessions with a remote vEdge router that is running a software release earlier than Release 16.2.0.

• When you add or remove an IPv4 address on a tunnel interface (TLOC) that already has an IPv6 address, or when you add or remove an IPv6 address on a TLOC that already has an IPv4 address, the control and data plane connections for that interface go down and then come back up.

• When you add or remove an IPv4 address on a tunnel interface (TLOC) that already has an IPv6 address, or when you add or remove an IPv6 address on a TLOC that already has an IPv4 address, the control and data plane connections for that interface go down and then come back up.
• Release 16.3 introduces a feature that allows you to configure the preferred tunnel interface to use to exchange traffic with the vManage NMS. In the vManage NMS, you configure this on cellular, Ethernet, and PPP Interface feature templates, in the vManage Connection Preference field under Tunnel Interface. In the CLI, you configure this with the vmanage-connection-preference command. The preference value can be from 0 through 8, with a lower number being more preferred. The default value is 5. If you set the preference value to 0, that tunnel interface is never used to exchange traffic with the vManage NMS, and it is never able to send or receive any overlay network control traffic.
  With this configuration option, there is one situation in which you can accidentally configure a device such that it loses all its control connections to all Viptela controller devices (the vManage NMSs and the vSmart controllers). If you create feature templates and then consolidate them into a device template for the first time, the NMS software checks whether each device has at least one tunnel interface. If not, a software error is displayed. However, when a device template is already attached to a device, if you modify one of its feature templates such that the connection preference on all tunnel interfaces is 0, when you update the device with the changes, no software check is performed, because only the configuration changes are pushed to the device, not the entire device template. As a result, these devices lose all their control connections. To avoid this issue, ensure that the vManage connection preference on at least one tunnel interface is set either to the default or to a non-0 preference value.

Interfaces

• On virtual interfaces, such as IRB, loopback, and system interfaces, the duplex and speed attributes do not apply, and you cannot configure these properties on the interfaces.

• When a vEdge router has two or more NAT interfaces, and hence two or more DIA connections to the internet, by default, data traffic is forwarding on the NAT interfaces using ECMP. To direct data traffic to a specific DIA interface, configure a centralized data policy on the vSmart controller that sets two actions—nat and local-tloc color. In the local-tloc color action, specify the color of the TLOC that connects to the desired DIA connection.

IPv6

• You can configure IPv6 only on physical interfaces (ge and eth interfaces), loopback interfaces (loopback0, loopback1, and so on), and on subinterfaces (such as ge0/1.1).
• For IPv6 WAN interfaces in VPN 0, you cannot configure more than two TLOCs on the vEdge router. If you configure more than two, control connections between the router and the Viptela controllers might not come up.
• IPv6 transport is suppoved over IPsec encapsulation. GRE encapsulation is not supported.
• You cannot configure NAT and TLOC extensions on IPv6 interfaces.

IRB

• On integrated routing and bridging (IRB) interfaces, you cannot configure autonegotiation.

NAT

• When you reboot a vSmart controller, the BFD sessions for all symmetric NAT devices go down and come back up. This is expected behavior.

Security

• In Releases 17.1 and earlier, you cannot disable the SSH HMAC-MD5 algorithm and other weaker algorithms.

SNMP

• When you configure an SNMP trap target address, you must use an IPv4 address.

• The Viptela interface MIB supports both 32-bit and 64-bit counters, and by default sends 64-bit counters. If you are using an SNMP monitoring tool that does not recognize 64-bit counters, configure it to read 32-bit MIB counters.

• On a vEdge router, if you perform an snmpwalk getnext request for an OID for which there is no information, the response that is returned is the next available instance of that OID. This is the expected behavior.

System

• In Releases 17.1 and earlier, you cannot disable the SSH HMAC, MD5, and other weaker algorithms.

• In Releases 17.1 and later, you cannot change the personality of a vEdge router to be a vBond controller, or vice versa, after certificates have been installed on the device.

Virtual Machines

• For a vEdge Cloud VM instance on the KVM hypervisor, for Viptela Releases 16.2.2 and later, it is recommended that you use virtio interfaces. For software versions earlier than Release 16.2.2, if you are using the Ubuntu 14.04 or 16.04 LTS operating system, you can use IDE, virtio, or virtio-scsi interfaces.

vManage NMS

• On a Viptela device that is being managed by a vManage NMS system, if you edit the device's configuration from the CLI, when you issue the commit command, you are prompted to confirm the commit operation. For example:
  vEdge(config-banner)# commit
  The following warnings were generated:
    'system is-vmanaged': This device is being managed by the vManage. Any configuration changes to this device will be overwritten by the vManage.
  Proceed? [yes,no]
  You must enter either yes or no in response to this prompt.
  During the period of time between when you type commit and when you type either yes or no, the device's configuration database is locked. When the configuration database on a device is locked, the vManage NMS is not able to push a configuration to the device, and from the vManage NMS, you are not able to switch the device to CLI mode.

• The members of a vManage cluster rely on timestamps to synchronize data and to track device uptime. For this time-dependent data to remain accurate, do not change the clock time on any one of the vManage servers of the cluster after you create the cluster.

• When you use the vManage Maintenance ► Software Upgrade screen to set the default software version for a network device, that device must be running Release 16.1 or later at the time you set the default software version. If the network device is running Release 15.4 or earlier, use the CLI request software set-default command to set the default software version for that device.

• When you are using a vManage cluster, when you are bringing up new vManage NMS in the cluster, use an existing vManage NMS to install the certificate on the new vManage NMS.

• In vManage feature configuration templates, for the passwords listed below, you cannot enter a cleartext password that starts with $4 or $8. You can, however, use such passwords when you are configuring from the CLI.

  • Neighbor password, in the BGP feature configuration template

  • User password, in the Cellular Profile feature configuration template

  • Authentication type password and privacy type password, in the SNMP feature configuration template

  • RADIUS secret key and TACACS+ secret key, in the System feature configuration template

  • IEEE 802.1X secret key, in the VPN Interface Ethernet feature configuration template

  • IPsec IKE authentication preshared key, in the VPN Interface IPsec feature configuration template

  • CHAP and PAP passwords, in the VPN Interface PPP Ethernet feature configuration template

  • Wireless LAN WPA key, in the WiFi SSID feature configuration template

Issues Fixed in Release 17.1.5

The following issues have been fixed in Viptela Software Release 17.1.5. The number following each issue is the bug number in the Viptela bug-tracking database.

Forwarding

• On a vEdge Cloud router, traffic shaping through QoS might not work properly. [VIP-26557: This issue has been resolved.]

Interfaces

• When you configure VRRP on an interface that is operationally down, that interface might become the VRRP master. [VIP-33505: This issue has been resolved.]

Policy

• When vEdge hardware and software routers are using application-aware routing, they may no longer honor the preferred action when all paths comply with the SLA and ECMP is used. [VIP-33650: This issue has been resolved.]

Security

• The DSCP in data traffic sent over a TLS connection from a server to a vSmart controller might not be set properly. [VIP-30056: This issue has been resolved.]

• When you uninstall the certificate from a vEdge Cloud router, the root certificate might also be removed. [VIP-34092: This issue has been resolved.]

System

• On a vEdge 2000 router, BFD sessions may go down and then come back up every 10-60 minutes. As a workaround, disable cflowd and DPI. [VIP-33784: This issue has been resolved.]

vManage NMS

• A vManage authentication failure returns the HTTP 200/OK code, with the HTML body containing "Invalid User or Password", instead of the standard HTTP 401/Unauthorized code. [VIP-32082: This issue has been resolved.]

• The vManage NMS might not display statistics for some tunnels. [VIP-34054: This issue has been resolved.]

• On the Configuration ► Templates page, you might not be able to scroll horizontally. [VIP-34205: This issue has been resolved.]

• After the ZTP process succeeds, pushing a configuration template might fail. [VIP-34288: This issue has been resolved.]

Issues Fixed in Release 17.1.4

The following issues have been fixed in Viptela Software Release 17.1.4. The number following each issue is the bug number in the Viptela bug-tracking database.

CloudExpress Service

• When an upstream router fails, the CloudExpress service might take up to 30 minutes to switch to the overlay network. [VIP-28136: This issue has been resolved.]

Forwarding

• When the options field in the TCP packet header includes the TCP MSS and other options, if the other options precede the TCP MSS option in the field, the TCP MSS adjustment might not take effect. [VIP-31509: This issue has been resolved.]

OMP

• Routes from a staged vEdge router might be advertised to non-staged vEdge routers. [VIP-31295: This issue has been resolved.]

Security

• The show tunnel statistics ipsec command displays no information about the count of inbound decrypted packets. [VIP-20637: This issue has been resolved.]

SNMP

• After you upgrade from Release 15.4.x to a Release 16.x release, you can no longer use a VRRP physical interface IP address for snmpget and snmpwalk operations, because the SNMP listener starts on VRRP virtual IP address instead of on the physical interface IP address. This issue has been resolved in Release 17.x releases. [VIP-29085: This issue has been resolved.]

vEdge Routers

• A vEdge 100 router might stop processing packets, and rebooting the router might not solve the problem. [VIP-31300: This issue has been resolved.]

vManage NMS

• With Japanese versions of the Chrome and IE browsers, the vManage NMS might not display some tables and other screen fields. [VIP-28870: This issue has been resolved.]

• The vManage NMS servers might reboot twice with the errors "'ncs failed..rebooting after ncs cdb cleanup" and "Daemon ‘ncs’ failed". After the reboots, the vManage servers might stop functioning. [VIP-28896: This issue has been resolved.]

• The vManage NMS should allow only one upgrade operation to be performed at a time, but sometimes it might attempt to perform two at the same time. [VIP-32084: This issue has been resolved.]

Issues Fixed in Release 17.1.3

The following issues have been fixed in Viptela Software Release 17.1.3. The number following each issue is the bug number in the Viptela bug-tracking database.

Configuration and Command-Line Interface

• If the default gateway next hop does not respond to an ICMP request, the vSmart controller does not install the next hop unless you remove the track-default-gateway command from the configuration. This problem is not seen on the vBond orchestrator. [VIP-25986: This issue has been resolved.]

Forwarding

• If you configure a translation rule on a NAT pool and then issue a show policy service-path command, the forwarding process (fp) might crash. [VIP-24417: This issue has been resolved.]

• When all the vSmart controllers connected to a TLOC fails, the IPsec connections between the vEdge routers might go down and come back up after control connections with the vSmart controllers are re-established. This happens only when port-hop is enabled. [VIP-27324: This issue has been resolved.]

• The traffic flow on LTE interfaces might remain very high even after you adjust timers on the interfaces. [VIP-27971: This issue has been resolved.]

• On vEdge 1000 and vEdge 2000 routers, when you enable fast deep packet inspection, which is used by the CloudExpress platform, DPI performance might suffer. [VIP-28008: This issue has been resolved.]

• On hardware vEdge routers, when packet fragmentation of data traffic sent over an IPsec tunnel occurs, a buffer leak might occur. [VIP-29314: This issue has been resolved.]

Interfaces

• When you upgrade a vEdge router to Release 17.1.0, PPP interfaces might reset often, in the process losing their IP addresses. When the interfaces come back up, they need to reconnect and authenticate via PPP, and it can take about 2 minutes to bring up the GRE tunnels. [VIP-28616: This issue has been resolved.]

Policy

• When you configure a centralized data policy that fails when it is applied on a vSmart controller, the failure error message might not clearly describe the problem. [VIP-27898: This issue has been resolved.]

Routing Protocols

• When you configure BGP in a dual-homed setup that has EBGP peering sessions to both BGP neighbors in the same ASN, the vEdge router might install routes only from one of the peers even though it is receiving routes from both of them. [VIP-28144: This issue has been resolved.]

Security

• If a vSmart controller becomes unreachable, the vEdge router might still show that controller as being reachable. [VIP-22262: This issue has been resolved.]

• During a POODLE attack against a TLS connection, all the device's CPU might be used or the vdaemon process might crash. [VIP-29376: This issue has been resolved.]

System

• The output of the traceroute command on a vEdge router might be incorrect. [VIP-23072: This issue has been resolved.]

• GRE tunnels might not leverage the interface MTU to automatically adjust their TCP MSS size. [VIP-28625: This issue has been resolved.]

vManageNMS

• In vManage NMS, you might not be able to delete a beta version of the Viptela software. [VIP-28672: This issue has been resolved.]

• After you upgrade the vManage NMS software, you might not be able to add the vAnalytics feature to an existing user group in the vManage Administration ► Manage Users ► User Groups screen. As a workaround, first create a new user group and then add the vAnalytics feature to that group. [VIP-29407: This issue has been resolved.]

Wireless WANs

• On a cellular interface, the show cellular radio command might display the wrong SNR classification, showing Poor instead of Excellent. [VIP-28847: This issue has been resolved.]

Issues Fixed in Release 17.1.2

Release 17.1.2 was not released.

Issues Fixed in Release 17.1.1

The following issues have been fixed in Viptela Software Release 17.1.1. The number following each issue is the bug number in the Viptela bug-tracking database.

CloudExpress Service

• You cannot direct CloudExpress traffic over a GRE tunnel. [VIP-26954: This issue has been resolved.]

Forwarding

• If you misconfigure a vSmart controller, the Forwarding Table Management process (ftmd) on the vEdge routers might crash when the routers receive OMP updates from the controller. [VIP-22116: This issue has been resolved.]

• When a Cisco phone is connected to a PoE interface on a vEdge 100wm router and the interface receives its IP address via DHCP, when DHCP renews its lease, the interface might periodically lose its assigned IP address. [VIP-26216: This issue has been resolved.]

Policy

• Application-aware routing policy might not take effect, causing data traffic to be directed to the incorrect tunnel interface. [VIP-26356: This issue has been resolved.]

Security

• On a vEdge router that has two Internet-facing interfaces, one of the interfaces might not be able to establish control connections or tunnels, and on this interface, many IPsec rekeying events might be occurring. [VIP-23870: This issue has been resolved.]

System

• If you do not use ZTP and if the Organization Name is not set on the vManage NMS and vEdge routers, control connections between the two devices might come up. [VIP-24246: This issue has been resolved.]

vManage NMS

• The vManage NMS might stop receiving event messages from the vEdge routers in the network. [VIP-21973: This issue has been resolved.]

• The Transport Interface pane on the vManage Dashboard might show information for non-transport interfaces. [VIP-21989: This issue has been resolved.]

• vEdge routers that have been marked as invalid might be listed in vManage device inventory API calls. [VIP-22410: This issue has been resolved.]

• When an admin user edits an existing CLI template, its device type is sometimes Null, so the user is unable to select the device type. [VIP-24182: This issue has been resolved.]

• On a standalone vManage NMS, the messaging bus might stop operating and then restart, but when it restarts the vManage application server does not restart. [VIP-25149: This issue has been resolved.]

• For an overlay network with a single vManage NMS, if the vManage NMS is stopped and move to another devices, the vManage services might not restart properly. [VIP-25692: This issue has been resolved.]

• Pushing a device configuration template from one of the vManage servers in a cluster might fail, with the "Failing with Server Not Leader" partition exception error. [VIP-25771: This issue has been resolved.]

• On the vManage Monitor ► Network screen, the real-time statistics displayed might be inaccurate. [VIP-26040: This issue has been resolved.]

• You might not be able to export the bootstrap configuration from the vManage server. [VIP-26209: This issue has been resolved.]

• For a vManage server using the Firefox browser, when you go to the Monitor ► Network screen, this screen might not display unless you refresh the page. [VIP-26755: This issue has been resolved.]

• If you edit an existing centralized policy on the vManage NMS and then re-apply the policy to vEdge routers, the policy might not work. As a workaround, copy the entire policy, delete the existing policy, and then paste the copied policy before re-applying it. [VIP-27048: This issue has been resolved.]
• If CSR generation on a vManage NMS fails, the log files provide no details about the reason for the failure. [VIP-27379: This issue has been resolved.]

• The vManage Configuration ► Certificates screen might not display the certificate icon for a router in the Valid state. [VIP-27380: This issue has been resolved.]

• You might not be able to save the vManage WiFi SSID feature configuration template. [VIP-27895: This issue has been resolved.]

Issues Fixed in Release 17.1.0

The following issues have been fixed in Viptela Software Release 17.1.0. The number following each issue is the bug number in the Viptela bug-tracking database.

Cellular Interfaces

• On a vEdge router, the show cellular status command does not reflect the current operational status of the modem. [VIP-13808: This issue has been resolved.]

• When you try to apply a device template that includes a cellular interface configuration to a device that does not already have a cellular profile defined, you might not be able to apply the template. [VIP-19372: This issue has been resolved.]

• If you have configured a profile for a cellular interface, when the interface is active, you cannot delete the profile. [VIP-20327: This issue has been resolved.]

• When you configure a cellular interface, you must configure a profile (with the cellular cellular0 profile command) before you can associate the profile with an interface (with the interface cellular profile command). [VIP-21569: This issue has been resolved.]

Configuration and Command-Line Interface

• On a vEdge router, when you issue the"show dhcp server bindings command that contains a syntax error, such as show dhcp server bindings h, the CLI might display the message, "Error: application communicate failure", and the router might crash. [VIP-25467: This issue has been resolved.]

Forwarding

• The flow collector on a vEdge router might fail to collect cflowd packet statistics. [VIP-11088: This issue has been resolved.]

• When there is conflicting decision regarding the path that a particular application needs to take, the CloudExpress configuration is overriding the decision made by data or application-aware routing policy. This is opposite of the expected behavior. [VIP-21863: This issue has been resolved.]

• When you are sending cflowd data to an external collector and the collector becomes unreachable, non-reachability messages are generated and written to the logs for every packet sent out for every flow. This process generates a huge number of log messages and might overwrite all other legitimate log messages. [VIP-22604: This issue has been resolved.]

• On vEdge routers, the routing table might not validate that a route is present in the forwarding table. [VIP-23091: This issue has been resolved.]

• On vEdge routers, the routing table might not validate that a route is present in the forwarding table. [VIP-23411: This issue has been resolved.]

• If a NAT-translated rule on a vEdge router receives an ICMP "error/unsupported proto" message, the forwarding process (fp) on the router might crash. [VIP-24220: This issue has been resolved.]

• When you disable BFD-based PMTU discovery on a vEdge router, the router might continue to receive PMTU packets. [VIP-25343: This issue has been resolved.]

• On a vEdge 2000 router, when there are a large number of cflowd flows, the Forwarding Table Management process (ftmd) might have high CPU utilization when writing flow data to the /tmp/xml files, and BFD sessions might go down and then come back up. [VIP-26346: This issue has been resolved.]

System

• The show bfd sessions command might indicate that BFD sessions are down when they are actually up. [VIP-12058: This issue has been resolved.]

• Copying cflowd statistics from vEdge routers to the vManage NMS might take a long time, especially when there are large amounts of statistics. [VIP-23519: This issue has been resolved.]

vEdge Hardware

• When you are using a fiber SFP, you are able to to configure no autonegotiate on the interface even though autonegotiation for 1000BaseT fiber is always enforced at the register level. [VIP-24490: This issue has been resolved.]

• On a vEdge 2000 router, if you enable DPI and if the flow creation and deletion rate is very high, the forwarding table manager (FTM) might use large amounts of memory while performing flow visibility, and eventually, an out-of-memory condition might occur. [VIP-25005: This issue has been resolved.]

vManage NMS

• vManage NMS might fail to make a Netconf connection to devices when attempting to collect statistics. [VIP-11087: This issue has been resolved.]

• When you upgrade from Release 16.1.2.3 to Release 16.2.2.1, the vManage NMS might lose all its stored network configurations and might then have to re-create them after the upgrade completes. [VIP-19454: This issue has been resolved.]

• When you attempt to push a software upgrade from the vManage NMS to a few vEdge routers, the vManage Dashboard might display the message "This server is not the leader for that partition exception", and the vManage server might not receive any event notifications. [VIP-21062: This issue has been resolved.]

• In the vManage Monitor ► Device Real-Time Data drop-down, the interface queue command is missing. [VIP-21796: This issue has been resolved.]

• The vManage server log files might contain a large number of duplicate BFD record messages. [VIP-22098: This issue has been resolved.]

• The vManage NMS might create alarms that are duplicates of previously created alarms. [VIP-22936: This issue has been resolved.]

• After you upgrade the vManage NMSs and vSmart controllers to Release 16.2.7, the vSmart controllers might not have the correct policy. As a workaround, deactivate and then reactivate the policy. [VIP-22980: This issue has been resolved.]

• The vManage dashboard might show the incorrect certificate expiration even after certificate has been renewed. [VIP-23779: This issue has been resolved.]

• When you push a configuration template from the vManage server, the headers on the template screen might become misaligned. [VIP-23881: This issue has been resolved.]

• In the VPN-Interface-NAT-Pool feature configuration template, you cannot create a variable for static NAT. [VIP-25563: This issue has been resolved.]

• You might not be able to edit existing user groups, to add new users to a group. [VIP-24312: This issue has been resolved.]

• A user associated with a group does not have permission to read and write cannot change their own password in the vManage Administration ► Manage Users screen. [VIP-24740: This issue has been resolved.]

If such a search request does not return relevant results, enclose the entire search string in quotation marks (here, for example, "full-cone NAT").
