Thank you for your fast reply
I have tried to update, but the only options I have are:
CiscoWorks Common Services
Device Fault Manager
Internetwork Performance Monitor
Resource Manager Essentials
For each, I am prompted for a CCO username and password; which we are unsure of? Will I get these direct from Cisco?
The device credentials are correct - I am able to telnet onto the router using them & enter enable mode. The snmp ro/rw strings are correct as per the running & startup configs.
I am able to go to "Device and Credentials" > "Device Management", select a device & "Edit Identity". Under "Cisco Router 800 Series", there is an 887, but I believe this was superceeded by the 887va?
