Service Manual

be configured on an interface if it is 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.
You can have 16 interfaces per Port Channel. The interfaces can be located on different
line cards but must be the same physical type and speed (for example, all 10-Gigabit
Ethernet interfaces).
For more information about Port Channels, refer to the Dell Networking OS
Configuration Guide.
