SNMP issue

[S Sadiq]

SNMP Response failing alarm were trigger 

>>No SNMP data is being reported from A-subpub01.abc.com Check that the snmp community has not been changed, either on the device or moniting tool

If the SNMP credentials are correct, check that a firewall is not blocking SNMP access to this device from the monitoring tool

Verified the SNMP configure at GW CLI

Do I have to run the utils snmp test ?

Any other troubleshooting need to be done

- Check if the SNMP service is active on the particular node or not

- Collect the PCAP from the effected node and filter it out by snmp, see the packets flow if it is correct or not [Check the IP etc].

- Validate the community string on CUCM and monitoring tool.

Thanks Abhay !

Can you guide the steps for checking above details.

As I logged into sub servicibility -Tools-Contact center feature service ->selected the node but didn't got and snmp details.

Another tab for SNMP which conails version ,mib but not sure so I left it

In the Control Center - Network Services window, verify that the system started the SNMP services.

Restart the SNMP Master Agent service in the Control Center - Network Features window.

Use the below link to collect PCAPs from CLI

ok,will there be any issue if I  Restart the SNMP Master Agent service from serviceability ?

and can I run

"utils network  capture eth0 file CUCMpackets count 100000 size all host ip 10.1.1.1 "

As 10.1.1.1 is my subscriber 

After collecting the PCAPs logs file what are the details I have searched (error code ,reason code.. etc )

[Abhay Singh Reyal]

It is quite expected that the restart of the SNMP service will impact in polling till the time it comes back up. 

Post the PCAP's here in the discussion.
