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 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 E-Series TeraScale, you can add up to 16 interfaces to a Port Channel; E-
Series ExaScale can add 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;
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.
