Caveats
•
CSCsg32646—If link aggregation (LAG) is enabled on the controller and the port channel is
configured on the infrastructure switch, the controller displays only a single entry for its neighbor
when you enter the sh cdp neighbor CLI command. When you enter the same command on the
switch, it displays two entries for the controller for two different ports that are part of LAG. The
controller should display two entries when the command is entered on the controller because the
switch sends the CDP message from two different ports that are part of the port channel.

reports that the transfer failed rather than that the file is not present.
Workaround: Make sure that the file and filename are entirely correct before upgrading, or upgrade
using the CLI to receive a more accurate reason for the failure. Even further details are available if
you use the debug transfer all enable command prior to upgrade.
