Usage
Information
Port Channel interfaces are logical interfaces and can be either in Layer 2 mode (by using the
switchport command) or Layer 3 mode (by configuring an IP address). You can add a Port Channel in
Layer 2 mode to a VLAN.
The shutdown, description, and name commands are the only commands that you can configure on an
interface while it is a member of a Port Channel. To add a physical interface to a Port Channel, the
interface can only have the shutdown, description, and name commands configured. The Port
Channel’s configuration is applied to the interfaces within the Port Channel.
A Port Channel can contain both 100/1000 interfaces and GE interfaces. Based on the first interface
configured in the Port Channel and enabled, FTOS determines if the Port Channel uses 100 Mb/s or
1000 Mb/s as the common speed. Refer to channel-member for more information.
If the line card is in a Jumbo mode chassis, then the mtu and ip mtu commands can also be configured.
The Link MTU and IP MTU values configured on the channel members must be greater than the Link
MTU and IP MTU values configured on the Port Channel interface.
port-channel failover-group Access the PORT-CHANNEL FAILOVER-GROUP mode to configure a
LAG failover group.
show interfaces port-channel Display information on configured Port Channel groups.
channel-number For a Port Channel interface, enter the keyword port-channel followed by a
number:
C-Series and S-Series Range: 1-128
E-Series Range: 1 to 32 for EtherScale, 1 to 255 for TeraScale and 1 to 512 for
ExaScale.
Version 8.1.1.0 Introduced on E-Series ExaScale
Version 7.6.1.0 Introduced on S-Series
Version 7.5.1.0 Introduced on C-Series
pre-Version 6.2.1.0 Introduced for E-Series
FTOS(conf)#int port-channel 2
FTOS(conf-if-po-2)#
Note: In a Jumbo-enabled system, all members of a Port Channel must be configured with the
same link MTU values and the same IP MTU values.
