We have recently noticed a problem with Cisco View not working on one particular device. This lead us to try to SNMP Walk the device but this failed. We have checked the RO Community String and Starting OID .22.214.171.124.126.96.36.199 which work fine on all other devices. Can anyone suggest anything else we could possibly try? The only coincidental fact is that the supervisor engine on the 6509 was replaced recently but we didn't think this should effect anything although everything was okay before this.
