I never got a response to this so I started digging through the code. It appears that VACM_MAX_STRING (32) controls this and a community/group/view name length cannot be equal to or larger than it.
My problem is that I was appending "_groupname" to the end of my community name to create the group name. Therefore a 22 character community name made a 32 character group name, which is not allowed. ---- On Fri, 19 Oct 2012 13:21:05 -0700 christopher.wu wrote ---- >For quite a while I have been under the impression that the maximum v2c >community or v3 username that I can use with snmpwalk is 32 characters.
