Dear NG,



i got a WS-C6506 on witch we got the following configured:



snmp-server ifindex persist



now after a system reload, for some reasons the OIDs for the modules change, the interfaces themselves are ok...

This command is intended for ifTable and ifXTable and their extensions. In most(many) mibs you should expect index is NOT persistent.

/hjj

well this seems to be a pain with tools like MRTG or similar, if you have to reconfigure all over an over again each time you reload the catalyst 650x...

any suggenstions on how to solve this issues are welcome!

No that just means you need to read the MRTG documentation... It was a pain in the first release, but since a very long time you can match your MRTG config lines on other fields of the interface, like name, IP address, description.

well the thing is my client is not using MRTG unfortuanitely... and he's now stuck with that problem. i just used MRTG for discussion reasons. but thank you for the tip!
