• mtu • ip mtu (if the interface is on a Jumbo-enabled by default) NOTE: A logical port channel interface cannot have flow control. Flow control can only be present on the physical interfaces if they are part of a port channel. NOTE: The switch supports jumbo frames by default (the default maximum transmission unit (MTU) is 9216 bytes). To configure the MTU, use the mtu command from INTERFACE mode. To view the interface's configuration, enter INTERFACE mode for that interface and use the show config command or from EXEC Privilege mode, use the show running-config interface interface command. When an interface is added to a port channel, the system recalculates the hash algorithm. To add a physical interface to a port, use the following commands. 1. Add the interface to a port channel. INTERFACE PORT-CHANNEL mode channel-member interface The interface variable is the physical interface type and slot/port information or port extender (PE) type and pe-id/unit-number/port-id information. 2. Double check that the interface was added to the port channel. INTERFACE PORT-CHANNEL mode show config Examples of the show interfaces port-channel Commands To view the port channel's status and channel members in a tabular format, use the show interfaces port-channel brief command in EXEC Privilege mode, as shown in the following example.
