Given it's failing on the new host but works on the old one I'm inclined to think it's a FW/ACL/whitelist/or piece of security software that is not allowing it.
The problem is SNMP uses UDP so there will be no response back, so we can't use nmap or traceroute to prove it's being blocked.
You'll either need to login to the network AND security devices along the network path it should take and review the logs OR grab a packet capture on the XI server and see what it shows when you run the command below as root on the NEW system (and leave it running):
Code: Select all
tcpdump -nni any -w /tmp/tcpdump_capture1.pcap
Then in another SSH session to the NEW server, run the check again to replicate the issue, then hit
CTRL+C the tcpdump command to stop it and attach the resulting
/tmp/tcpdump_capture1.pcap so we can review it.
Thank you!
