NAC 3310- cannot connect to with serial connection

[Kristen Sims]

I have (2) 3310 NAC appliances that someone else set up and configured. I need to access via a serial connection to my laptop to upgrade the software. I cannot connect via Hyperterm. I have 4 other NAC appliances that I can connect to fine via direct laptop serial connection. My hyperterm settings are correct. Log files do not show anything that could be causing this (per TAC). I can access via ssh over the network, and through the web gui.

Issue is fixed.

Kristen,

Glad to hear that. So that someone else might also benefit from the resolution, perhaps you wouldn't mind posting it here too?

Thanks,

Faisal

Short description is, I serial connected to the CAS's to do

a software upgrade, and could not get a connection to either of them. Through troubleshooting it seemed there were other issues going on with the Active CAS. Once I rebuilt (re-installed software) and reconfigured the HA pair, I was able to serial connect to both and then proceed with the upgrade.
