I am upgrading via http. In the instructions it say's to disable the controller port-channel then download the code. When you disable the port-channel you lose connection to the wism. am I missing something? how would that work?
Good afternoon. If you are using a wism blade in a 6500 chassis you can still disable the port channel and have access to the wism. This could be done by using the session slot x processor 1/2 command on the 6500 cli
I got the upgrade to work without shutting off the port-channel interfaces.
Edit -> I just tried this... put an edge switchport in the same Vlan as the "non-routable" Wism service vlan, assigned it a static IP address in the Wism service subnet, router as wism service vlan router... and was able to connect to the service port interface.
Should work for your TFTP server. I have no idea how to TFTP from the command line in the wism though - it's pretty cryptic.
