For obvious security reasons, I'd rather not have RW SNMP on any of my routers or switches. I am told however that CiscoWorks requires RW SNMP for some of it's functions, particularly automated config changes etc.
Can someone confirm that? Can I make full use of CW2K without SNMP RW access? It seems like a bit of a contradiction on Cisco's part, as i've seen many security documents on CCO that strongly recommend NEVER to use RW SNMP, but then they put out tools that rely on it???
For just doing the discovery, RO is needed. RW is only needed to allow write access to the devies. If you do not specify the RW string for the specific target, the default value of private is used. Refer to the on-line help within Campus Manager for more details.
Note that if you want to use RTM you'll need to use the read-write-all community name from your Catalyst switches as the write community in your RTM configuration. The read-write community name from the switch wont do it.
