SSH user stuck Cisco 2960

[network_matoda]

Dear All,

I have Cisco 2960 switch in my organization and I am facing issue in this switch, when I configure SNMP it's CPU is goes till 99% and after remove the SNMP its normal.

I have checked and got SNMP Engine is taking high CPU utilization.

after removing the SNMP I am not able to run some commands (show startup-config, write-mem etc.) and I see the ssh login user and found it stuck I have tried to clear user login as well but no luck also try the same commands on console as well but same issue.

Please help to resolve the same.

Hello,

try:

no snmp-server

then reboot the switch, or wait for a few minutes, then re-enable it:

snmp-serveru
