Interfaces | 595
If the Port Channel contains a mix of interfaces with 100 Mb/s speed and 1000 Mb/s speed, the
software disables those interfaces whose speed does not match the speed of the first interface
configured and enabled in the Port Channel. If that first interface goes down, the Port Channel does not
change its designated speed; you must disable and re-enable the Port Channel or change the order of
the channel members configuration to change the designated speed. Refer to the FTOS Configuration
Guide for more information on Port Channels.
