Instead of using SNMP TRAPS I would like to use INFORM requests. When I receive TRAPS everything is working correcty. When I receive INFORM requests, the source interface is reported wrong.
snmp-server trap-source Loopback0
snmp-server source-interface informs Loopback0
snmp-server enable traps snmp linkup
snmp-server enable traps config
snmp-server host 10.101.1.15 inform version 2c public
snmp-server host 10.101.1.15 version 2c public
The TRAPS report their source address as Loopback0 but the INFORMS report their source address as FastEthernet0.
we are also migrating from traps to informs and I can see that this source-interface issue is still open. I can confirm it is happening on Cisco 7609-S with IOS: 12.2.(33)SRD5, SRD6 and SRE2.
In bug toolkit I can see it opened for 6500 under CSCtc43231 (http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCtc43231) but there is no any SR release under affected versions.
If anyone knows any workaround, I would appreciate it a lot.
Thanks in advance!
Thanks guys for quick responses!
Thanks for sharing info. Unfortunately, we have to use informs, so I need to find a way to configure it with good source. I'll post solution if I find any.
Thanks for suggestion. I already opened TAC case for affected versions. I'll inform you on the conclusion of the case. Currently I'm collecting all relevant output, debugs and packet captures for developers.
