Switch 2960X - problem with SNMP

[Jan23]

Hi,

I am trying to use NetCrunch to manage my network. I activated the SNMP protocol on switches.

SNMP works fine, but not on all switches. I have two main switches (2960X) and I can't get the forwarding table.

One of the switches has an error: LSYSTEM.BUFFERNOMEM 32,748 is over threshold value 5

Why can't I get the forwarding table? - as a result, the program badly generates connections in the infrastructure

In addition, CDP works on all switches.

Thank you in advance for your help.

SNMP works fine, but not on all switches.

what is the difference between work vs not working?

what is the version of IOS Code running, what kind of forwarding table you looking to get from Switch ? is the switch Layer 3 ?

regarding memory see what process running :

show process memory

Hello,

which OID are you polling on the 2960X switches to get the forwarding table ?

The error messages point to some sort of memory problem. Post the output of:

sh processes memory sorted | exclude 0.00
