If you cannot get into enable mode, and you've rechecked the credentials, the problem is most likely command authorization. Before RME enables itself, it performs the following commands:
terminal length 0
terminal width 0
All of those commands must succeed. The easiest way to determine the problem for sure, though, is to get a sniffer trace of all telnet traffic to the switch when a sync archive job is running. It should then become very clear what is going wrong.
Thanks Joe. I will have to use a sniffer as those commands are coming through in the ACS logs for devices that are successful, but nothing is showing up for the unsuccessful devices in "Tacacs+ Administration active".
For others reading this post, I am troubleshooting in ACS by viewing Reports and Activities;
- Passed Authentications. This shows two lines, with privelege levels 1 and 15.
- TACACS+ Accounting active. This shows one line, with the "disc-cause" showing up as "lost-carrier"
- Tacacs+ Administration active. This shows successful commands during a Sync Archive of a device.
I ran a sniffer and found that the switch was gettting into enable mode, then dropping out for some reason.
I then loaded the device into our DEV instance of RME and was able to successfully manage this device. It took me a while to work out what was different, but the Dev device was picking up the device as a 6506 rather than a 6509.
Deleting and re-entering the device into our PROD RME server worked as the device was now detected as a 6506. I'm not sure what the difference is between these models that would stop a config retrieval, but this seemed to be enough.
What I thought was strange, however, was that RME did not flag that device as "Conflicting", even thought inventory collections on this device were successful.
