i am getting same error for multiple node.

Error :- WARNING: SNMP error: No response from remote host '10.10.165.38'

Can you suggest me permanent fix for the same as per Node owner and MPBN team connectivity is fine and 161/162 put is open.

but i am getting the same as shared below. They need a artifacts for the same. Can you help me out to get rid of this as we are getting 10k alert for the same SNMP error.

It keep on fluctuating. Please find the logs.

SNMP is over UDP so the packets could be getting lost somewhere. Are there any firewalls or other devices between XI and the remote host that may be dropping these? Can you see on the remote host if the requests made by XI reach it?

Are there any firewalls or other devices between XI and the remote host that may be dropping these? ---> how we can check at our end. what needs to done at network team.

Can you see on the remote host if the requests made by XI reach it ----> how can we check the same?

A tcpdump can be run on the XI machine with:

tcpdump -s 0 -i any host 10.10.165.38 -w output.pcap

let it run just long enough to reproduce the error, then use CTRL+C to stop it and it can be reviewed with the wireshark program.
