cmnMacAddressesLearnt returning a result of 0

ascension2020 over 12 years ago

Hi,

I'm trying to create a custom poller in NPM to find the # of MAC addresses in use on a switch. This particular poller will be used on Cisco 3750s and 6509s.

I thought that cmnMacAddressesLearnt (1.3.6.1.4.1.9.9.215.1.1.3) would be a good place to start. The description is:

"Indicates the number of MAC addresses learnt by the device."

Orion has that MIB, and it is supported by my switches, but when I test it against my switches it returns a result of 0 for all of them. That's obviously not correct, even if that MIB is just counting MACs that were dynamically learned.

Am I approaching this the wrong way? Is there another MIB I should be using? Any insight is appreciated...

Thanks,
Josh

Thanks, I have looked at doing it that way, but if Cisco has a MIB that will tell me the # of MACs without having to do any calculations then that would be the best option.
