Cisco ISE SNMP issue

[Harshsahota]

Hi,

I am trying to troubleshoot an SNMP issue with ISE where a secondary admin node has stopped responding to the SNMP queries. I have verified from TCPdump that the SNMP request is coming to the ISE but it is not responding back. I enabled SNMP debugs on the ISE but ISE didn't generate any debugs. Checked under log messages as well, but couldn't find any SNMP error. Tried to check the running configuration but the secondary(admin) ISE wouldn't generate the configuration output and is stuck at the show running-configuration command. Any help would be appreciated.   

TCP Dump:

Adding the SNMP configuration again fixed the issue 

[JohnathanWilkes]

Did adding SNMP configuration permanently fix the issue?

[m.soleimani]

[wolfgang.lochbihler]

This happens at our customers on almost regular basis

ise-001/admin(config)# no snmp-server enable

ise-001/admin(config)# snmp-server enable

and everything works fine
