Topology: Layer 2 Poller

Question

After upgrading to 10.2, I've noticed that the Layer 2 poller is missing from some seemingly random devices. How does NPM determine which pollers to apply to which devices and how I can I manually add them if NPM doesn't?

I would love to know how these pollers work because when they're running against a device, they seem to work really well. I've gotten a few topology results that are odd though. I would appreciate a write-up of how they work so I can troubleshoot them.

Topology Layer 2 is assigned to devices which provide OID

dot1qTpFdbPort = "1.3.6.1.2.1.17.7.1.2.2.1.2"
or
dot1dBasePort = "1.3.6.1.2.1.17.1.4.1.1"

Can you see pollers assigned in "List Resources" on suspected node? If so and you still can't see results, maybe it's because topology on this device takes longer than expected. In that case please open a support ticket and we will help you to resolve it.

thanks
