I have two identical Routers Cisco 3640 .Both have the same version of IOS .Yet one when i do a show int ; does not show anything .The IOS version I have put on it is C3640-I-M), Version 12.2(17a), Both Routers have 8192K bytes of processor board System flash (Read/Write) .
This router was working fine till I decided to Upgrade the IOS .
The error message on the faulty router is
6:12:07: %IP_SNMP-3-SOCKET: can't open UDP socket
06:12:07: Unable to open socket on port 161
Obviously I am trying to install a feature set which this router does not like .Any help appreciated .
