You need to pick a starting OID, or expect to wait a _long_ time. It's best to test something simple like sysObjectID as a starting OID. Yes, you can use SNMP Walk on devices that are reported as unreachable, but you will need to use correct SNMP credentials before the SNMP Walk utility will work. So, if you know the credentials are correct when using SNMP Walk, but it reports that the walk timed out, then there is something blocking the SNMP traffic, or your credentials or device configuration is still wrong.

If the device is not SNMP reachable, then no package updates will ever fix that. Verify the SNMP community strings with your network guys, and make sure the CiscoWorks server is allowed to query it via SNMP (this is completely independent from pings, but ICMP will also be required for DFM).

You can use the SNMP Walk utility under Device Center to test to make sure the community string configured in the Device Credential Repository is correct.

Re: ASA firewall 5520 in ciscoworks 2.6

The ASA devices are not supported by Campus Manager, so they will not show up as known in Data Collection. Provided the community strings are correct in your Device Discovery settings, and the ASA devices are added as seed devices, they should be reachable for discovery. However, if they are already in DCR, then you don't need to worry about discovery finding them. What really matters if apps like RME and DFM can communicate with them.
