Reference Guide

An interface can belong to only one Port Channel.
You can have 16 interfaces per Port Channel on the S-Series and Z-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; 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; 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 Dell Networking OS Configuration Guide.
