Simulator cant send SNMP requests back to system manager 2.1 on the same subnet
2013-05-29 11:55 PM
I've just done my first install of a cDOT 8.2 simulator on my win7 corp laptop with VMware player and everything works well except for one odd thing
The node simply fails when sending an snmp reply, so things like discovery on system manager simply doesnt work
snmp.agent.resp.failed: Could not send response to host : 192.168.112.1 : reason : Failure could be due to either DNS/gateway misconfiguration or t...
This message occurs when the SNMP daemon attempts to send a response, and the attempt fails.
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
This seems a little odd, given that the 192.168.112 subnet is the Vmnet8 network (the NAT network),

on my laptop
Ethernet adapter VMware Network Adapter VMnet8:
Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::dfc:e60c:7d8c:3760%25
IPv4 Address. . . . . . . . . . . : 192.168.112.1
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . :
So it's not likely to be a routing issue, and I cant see why it would be wanting to do a DNS lookup at either end.
It isnt urgent, but I'd appreciate any thoughts the brains trust might have, if neccesary I'll set up hosts tables on my laptop and the cluster, but I wouldnt have thought that would be neccesary.

SNMP is not enabled by default in CDOT.
Use the admin credentials to add it to system manager. Use a 3.x release of system manager.
Once in you can enable snmp and drop in your community strings and trap hosts from the gui. CLI is always an option as well.
