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.

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.
