www.dell.com | support.dell.com You can add any physical interface to a port channel if the interface configuration is minimal. Only the following commands can be configured on an interface if it is a member of a port channel: • description • shutdown/no shutdown • mtu • ip mtu (if the interface is on a Jumbo-enabled by default.) Note: The S-Series supports jumbo frames by default (the default maximum transmission unit (MTU) is 1554 bytes) You can configure the MTU using the mtu command from INTERFACE mode. To view the interface's configuration, enter the INTERFACE mode for that interface and enter the show config command or from the EXEC Privilege mode, enter the show running-config interface interface command. When an interface is added to a port channel, FTOS recalculates the hash algorithm. To add a physical interface to a port channel, use these commands in the following sequence in the INTERFACE mode of a port channel: Step Command Syntax 1 channel-member interface 2 show config Command Mode Purpose INTERFACE PORT-CHANNEL Add the interface to a port channel. The interface variable is the physical interface type and slot/port information. INTERFACE Double check that the interface was added to PORT-CHANNEL the port channel. To view the port channel's status and channel members in a tabular format, use the show interfaces port-channel brief command in the EXEC Privilege mode, as shown in the following example. FTOS#show int port brief LAG Mode Status 1 L2L3 up 2 L2L3 up FTOS# Uptime 00:06:03 00:06:03 Ports Gi 13/6 Gi 13/12 Gi 13/7 Gi 13/8 Gi 13/13 Gi 13/14 (Up) * (Up) (Up) * (Up) (Up) (Up) The example below displays the port channel's mode (L2 for Layer 2 and L3 for Layer 3 and L2L3 for a Layer 2 port channel assigned to a routed VLAN), the status, and the number of interfaces belonging to the port channel.
