VPN Interface DSL PPPoE

Device Specific (indicated by a host icon)

Use a device-specific value for the parameter. For device-specific parameters, you cannot enter a value in the feature template. You enter the value when you attach a Viptela device to a device template.

When you click Device Specific, the Enter Key box opens. This box displays a key, which is a unique string that identifies the parameter in a CSV file that you create. This file is an Excel spreadsheet that contains one column for each key. The header row contains the key names (one key per column), and each row after that corresponds to a device and defines the values of the keys for that device. You upload the CSV file when you attach a Viptela device to a device template. For more information, see Create a Template Variables Spreadsheet.

To change the default key, type a new string and move the cursor out of the Enter Key box.

Examples of device-specific parameters are system IP address, hostname, GPS location, and site ID.

Global (indicated by a globe icon)

Enter a value for the parameter, and apply that value to all devices.

Examples of parameters that you might apply globally to a group of devices are DNS server, syslog server, and interface MTUs.

Select the operating mode of the VDSL controller from the drop-down:

• Auto—Default mode.
• ADSL1—Use ITU G.992.1 Annex A full-rate mode, which provides a downstream rate of 1.3 Mbps and an upstream rate of 1.8 Mbps.
• ADSL2—Use ITU G.992.3 Annex A, Annex L, and Annex M, which provides a downstream rate of 12 Mbps and an upstream rate of 1.3 Mbps.
• ADSL2+— Use ITU G.992.5 Annex A and Annex M, which provides a downstream rate of 24 Mbps and an upstream rate of 3.3 Mbps.
• ANSI—Operating in ADSL2/2+ mode, as defined in ITU G.991.1, G.992.3, and G992.5, Annex A and Annex M, and in VDSL2 mode, as defined in ITU-T G993.2.
• VDSL2—Operate in VDSL2 mode, as defined in ITU-T G.993.2, which uses frequencies of up to 30 MHz to provide a downstream rate of 200 Mbps and an upstream rate of 100 Mbps..

Click Yes to enable seamless rate adaptation on the interface. SRA adjusts the line rate based on current line conditions.

Enter the maximum receive unit (MRU) value to be negotiated during PPP Link Control Protocol (LCP) negotiation.
Range: 64 through 1792 bytes

Configure the IP prefix of the dialer interface. This prefix is that of the node in the destination that the interface calls. 

• Negotiated—Use the address that is obtained during IPCP negotiation.

Select the authentication protocol used by the MLP:

• CHAP—Enter the hostname and password provided by your Internet Service Provider (ISP). hostname can be up to 255 characters.
• PAP—Enter the username and password provided by your ISP. username can be up to 255 characters.
• PAP and CHAP—Configure both authentication protocols. Enter the login credentials for each protocol. To use the same username and password for both, click Same Credentials for PAP and CHAP.

Specify the maximum number of vSmart controllers that the WAN tunnel interface can connect to. To have the tunnel establish no control connections, set the number to 0.

Range: 0 through 8
Default: 2

Use GRE encapsulation on the tunnel interface. By default, GRE is disabled.

If you select both IPsec and GRE encapsulations, two TLOCs are created for the tunnel interface that have the same IP addresses and colors, but that differ by their encapsulation.

Use IPsec encapsulation on the tunnel interface. By default, IPsec is enabled.

If you select both IPsec and GRE encapsulations, two TLOCs are created for the tunnel interface that have the same IP addresses and colors, but that differ by their encapsulation.

Specify a preference value for directing traffic to the tunnel. A higher value is preferred over a lower value.

Range: 0 through 4294967295
Default: 0

Enter a weight to use to balance traffic across multiple TLOCs. A higher value sends more traffic to the tunnel.

Range: 1 through 255
Default: 1

Select the carrier name or private network identifier to associate with the tunnel.

Values: carrier1, carrier2, carrier3, carrier4, carrier5, carrier6, carrier7, carrier8, default
Default: default

Enter the time to wait for a Hello packet on a DTLS or TLS WAN transport connection before declaring that transport tunnel to be down.

Range: 12 through 60 seconds
Default: 12 seconds

Select how NAT mappings are refreshed, either outbound or bidirectional (outbound and inbound).
Default: Outbound

Specify when NAT translations over UDP sessions time out.
Range: 1 through 65536 minutes
Default: 1 minutes

Specify when NAT translations over TCP sessions time out.
Range: 1 through 65536 minutes
Default: 60 minutes (1 hour)

Select On to block inbound ICMP error messages. By default, a router acting as a NAT device receives these error messages.
Default: Off

Enter a port number to define the port or first port in the range of interest.
Range: 0 through 65535

Configure the aggreate traffic transmission rate on the interface to be less than line rate, in kilobits per second (kbps).

Click On, and specify the name of the access list to apply to IPv4 packets being received on the interface.

Click On, and specify the name of the access list to apply to IPv6 packets being received on the interface.

Enter the name of the physical interface on the same router that connects to the WAN transport circuit. This configuration then binds this service-side interface to the WAN transport. A second router at the same site that itself has no direct connection to the WAN (generally because the site has only a single WAN connection) and that connects to this service-side interface is then provided with a connection to the WAN.
