Users Guide

You can have 16 interfaces per Port Channel on the S-Series and Z-Series. The interfaces can be located on
dierent 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 rst interface congured and
enabled in the Port Channel. If that rst 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
conguration 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 rst interface congured and enabled in the Port Channel. If that rst 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 conguration to change the designated speed. For more information about
Port Channels, refer to the Dell Networking OS Conguration Guide.

To remove an existing LAG supergroup, use the no group group_number command.
Parameters
group_number Enter an integer from 1 to 32 that uniquely identies this LAG fate-sharing group.
