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. 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. For more information about Port Channels, refer to the
FTOS Configuration Guide
