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.
