I currently have multiple vlan's created on (2) 6509's running hsrp betweem the vlans. All host on the vlan's are nat. The 6509's are connected to firewall and then the firewalls are connected to (2) 7200's. I have an SNMP server sitting off of the 7200's on the real IP network. My question is how can I get snmp traps off the nated vlan's. If you need additional information to answer this question please advise. Thanks
Since there has been no response to your post, it appears to be either too complex or too rare an issue for other forum members to assist you. If you don't get a suitable response to your post, you may wish to review our resources at the online Technical Assistance Center (http://www.cisco.com/tac) or speak with a TAC engineer. You can open a TAC case online at http://www.cisco.com/tac/caseopen
If anyone else in the forum has some advice, please reply to this thread.
Without more info, all I can suggest is to make sure that SNMP is getting NATted just like everything else.
Are you only NATting TCP, or only specific protocols/ports on the firewalls? If you are natting everything, I would expect the traps to be natted just as well.
Also, your trap configuration on the 6509s should point to the external IP of the SNMP server.
In the end, without more details about the topology & config, we can only speculate as to why this is not working. I may be that with the complexity of the network & the multiple protocols/features in use, a TAC case may be the best route.
