- Full WAN Connectivity—Total number of sites where all BFD sessions on all vEdge routers are in the up state.
- Partial WAN Connectivity—Total number of sites where a TLOC or a tunnel is in the down state. These sites still have limited data plane connectivity.
- No WAN Connectivity—Total number of sites where all BFD sessions on all vEdge routers are in the down state. These sites have no data plane connectivity.
Click a row to display a popup window with detailed information on each site, node, or tunnel. Click the More Actions icon to the right of each table row to access the Device Dashboard or Real Time view in the Monitor ► Network screen or the Tools ► SSH Terminal screen.
Transport Interface Distribution
The Transport Interface Distribution pane displays interface usage in the last 24 hours for all vEdge interfaces in VPN 0. This includes all TLOC interfaces. Click a row to see details of interface usage.
vEdge Inventory Pane
The vEdge Inventory pane provides four counts:
- Total—Total number of vEdge routers whose authorized serial number has been uploaded on the vManage server. The serial number is uploaded in the Configuration ► Devices screen.
- Authorized—Total number of authorized vEdge routers in the overlay network. These are routers marked as Valid in the Configuration ► Certificates ► vEdge List screen.
- Deployed—Total number of deployed vEdge routers. These are routers marked as Valid that are now operational in the network.
- Staging—Total number of vEdge routers in staging state. These are routers you configure at a staging site before shipping them to the actual branch and making them a part of the overlay network. These routers do not take part in any routing decisions nor do they affect network monitoring through the vManage NMS.
Click any row to display a table with the hostname, system IP, site ID, and other details of each router.
vEdge Health Pane
The vEdge Health pane displays an aggregated view for each router state and a count of how many vEdge routers are in that state, thereby describing the health of the hardware nodes. The three states are:
- Normal—Number of routers with memory, hardware, and CPU in normal state. Using less than 70% of total memory or total CPU is classified as normal.
- Warning—Number of routers with memory, hardware, or CPU in warning state. Using between 70% and 90% of total memory or total CPU is classified as a warning.
- Error—Number of routers with memory, hardware, or CPU in error state. Using more than 90% of total memory or total CPU is classified as an error.
Click the number or the state to display a table with the last 12 or 24 hours of memory usage, CPU utilization, and hardware-related alarms, including temperature, power supply, and PIM modules.
