Introduced on S-Series. Introduced on C-Series. Introduced on E-Series. 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. 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. Dell(conf)# int port-channel 2 Dell(conf-if-po-2)# channel-member - adds a physical interface to the LAG. interface - configures a physical interface. interface loopback - configures a Loopback interface. interface null - configures a null interface. interface vlan - configures a VLAN. shutdown - disables/enables the port channel. minimum-links Configure the minimum number of links in a LAG (Port Channel) that must be in "oper up" status for the LAG to be also in "oper up" status.
