I got a PIX 506E that has been discovered and collected from Campus Manager.
However, inventory collection fails with the PIX 506E, while all credentials are ok and tested.
Transport Session to device failed. Cause Authentication failed on device.
May be the problem could be with the SNMP CREDENTIALS ro and rw
There are a few things you can try to see which credentials are failing
First perform a check device credentials and see which are failing...snmp, telnet, ssh...
Then do a packet capture during inventory collection to see where authentication is failing. I would check the telnet/ssh credentials.
