Command
History
Version 9.0(1.3) Introduced on the S5000.
Usage
Information
Use the interface port-channel command to access this command.
You cannot add an interface to a Port Channel if the interface contains an IP
address in its configuration. Only the shutdown, description, mtu, and ip mtu
commands can be configured on an interface if it is to be added to a Port Channel.
The mtu and ip mtu commands are only available when the chassis is in Jumbo
mode.
Link MTU and IP MTU considerations for Port Channels are:
• All members must have the same link MTU value and the same IP MTU value.
• The Port Channel link MTU and IP MTU must be less than or equal to the link
MTU and IP MTU values configured on the channel members. For example, if
the members have a link MTU of 2100 and an IP MTU 2000, the Port Channel’s
MTU values cannot be higher than 2100 for link MTU or 2000 bytes for IP MTU.
When an interface is removed from a Port Channel with the no channel-member
command, the interface reverts to its configuration prior to joining the Port
Channel.
An interface can belong to only one Port Channel.
On the S5000, you can have eight interfaces per Port Channel. The interfaces can
be located on different stack-units 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.

description – assigns a descriptive text string to the interface.
interface port-channel – creates a Port Channel interface.
shutdown – disables/enables the port channel.
group
Group two LAGs in a supergroup (“fate-sharing group” or “failover group”).

Syntax
group group_number port-channel number port-channel number
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 identifies this LAG
fate-sharing group.
port-channel
number
Enter the keywords port-channel followed by an existing
LAG number. Enter this keyword/variable combination twice,
identifying the two LAGs to be paired.
