Interface IPs not visible for Versa SD-WAN devices in CA Performance Management (CAPM)

• CA Performance Management - Usage and Administration

Issue/Introduction

IP address of the VNI interfaces from Versa SD-WAN appliances are not shown in CAPM:

This is even though when looking at the MIB data returned from the device, we can see the IP (192.168.0.1) in indexes 12 & 13:

1.3.6.1.2.1.4.22.1.1.12.192.168.0.1, Integer     , 12
1.3.6.1.2.1.4.22.1.1.13.192.168.0.1, Integer     , 13

 

 

 

 

Environment

DX NetOps CAPM all currently supported releases

Cause

The IP in the OID queries is not the Interface (IF) IP of ifIndex 12 and 13. It's the IP that interface 12 and 13 heard about. In this case IP 192.168.0.1 is a neighbor device that this device's IF 12 and 13 heard about:

1.3.6.1.2.1.4.22.1.1.12.192.168.0.1, Integer     , 12
1.3.6.1.2.1.4.22.1.1.13.192.168.0.1, Integer     , 13

To find out if an interface has an IP or not, you can query this OID: 1.3.6.1.2.1.4.34.1.3 (ipAddressIfIndex)

1.3.6.1.2.1.4.22.1.1 / ipNetToMediaIfIndex is of the ARP MIB table.

The ipAddressTable (1.3.6.1.2.1.4.34.1) is the device interface IP table.

So the end result is that this device doesn't support MIB ipAddrTable as they don't exist in the MIB and we cannot find any IPs on the device.

Resolution

You can check the Virtual Interfaces in the Inventory->Virtual Interfaces page. It should have the IP address for VNA only interfaces.

And CAPM would sync the vni interfaces from VNA to the ones obtained above via SNMP polling.
