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) with an exception that when the PE ports are
configured as a member of Port Channel you can configure that Port Channel in Layer 2 mode (using the
switchport command) and add it to a VLAN.
In the Configuration Terminal Batch mode, you can configure the Port Channel in a dual-homing setup.
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, the system determines if the Port Channel uses 100 Mb/s or 1000 Mb/s as the
common speed. For more information, refer to channel-member.
If a port extender (PE) is provisioned, cascade LAGs are created automatically (auto-LAGs). You cannot configure
the port-channel created through the auto-LAG. The range for the port-channel created through auto-LAG is
from 257 to 513.
If the line card is in a Jumbo mode chassis, you can also configure the mtu and ip mtu commands. 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.
