Upgraded 2 3550-24 with 2 3560E-24 migrated config over to new switches
and I am unable to communicate with them via snmp v2 with the RO string. I have tried
several programs including LMS 3.1. I have removed the strings and re-added them from known
good configs still nothing. I did have an ACL on the strings and removed it with no luck.
I started out with 12.2(46)SE and upgraded to 12.2(50)SE with no improvement.
The SNMP portion looks good. I did notice your logging configuration might be problematic. How were you verifying the debug output? From what I could tell, you would have to have been running it on a VTY with "term mon" enabled.
