Interfaces
When an interface is removed from a Port Channel with the
interface reverts to its configuration prior to joining the Port Channel.
An interface can belong to only one Port Channel.
On the E-Series TeraScale, you can add up to 16 interfaces to a Port Channel; E-Series ExaScale can
have up to 64. You can have eight interfaces per Port Channel on the C-Series and S-Series. The
interfaces can be located on different line cards but must be the same physical type and speed (for
example, all 1-Gigabit Ethernet interfaces). However, you can combine 100/1000 interfaces and GE
interfaces in the same Port Channel.
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.
