I have seen a couple of threads on this issue but, unfortunately, they haven't been able to recitfy the issue for me.
So, IHAC running a 2040 on DOT 126.96.36.199 (can't run 8 because of a snapmirror relationship to a 2020), and they are seeing the below message on the CLI every few minutes:
[f<hostname> snmp.agent.resp.failed:warning]: Could not send response to host :<ip address> : reason : Failure could be due to either DNS/gateway misconfiguration or takeover/giveback in progress
I have tried to get them to set up a static route for this host by running route add <host_ip> <gateway> 1 but they get a message of "Entry already exists"
Anyone have any suggestions??
Looks like you are on the right track. According to NOW the corrective action is:
"Check your network configuration, primarily the DNS and gateway setup. The SNMP send response might also fail if a takeover/giveback was in progress or a forced reboot was performed"
You might also check DNS entries to ensure there are proper forward and reverse entries for the destination. Failing that is cf enabled with SSI?
