I have two identical Catalyst 5505 switches and use Config Download to pull configs off of them. At the recommendation of one of our auditors we placed a read-write-all snmp string on them in addition to our unique r/w string. When we did this we lost the ability to pull configs from one of the switches. Also it does not respond to B/W Monitor. We get a message that is is not responding to the snmp string. We carefully verified the string but no go. The r-w-all string was removed but no change. One of the switches continues to respond normally. Am I missing something obvious to anyone here or anybody have any ideas?
