HINT: ifAlias length is not limited to 64 characters, check your CISCO config!


not a help request, just a heads up, in case somebody has the same problem.
I was just about to open feature request, but then I found out, I had a L8-issue here.

If you see the ifAlias of your CISCO-device ports cut off after 64 characters,
please ensure that your device config has this:

snmp ifmib ifalias long

otherwise your CISCO-device will cut off after 64 characters.
Using this option will allow all 256 characters.

Got the hint from “them”:

Best regards,


Thanks awaum for posting this fix, we just had the same problem, it cut off the interface description after 64 characters.
