Concept Guide

NOTE: The switch supports jumbo frames by default (the default maximum transmission unit [MTU] is 1554 bytes) You can
congure the MTU using the mtu command from INTERFACE mode.
To view the interface’s conguration, 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.
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.
2 Double check that the interface was added to the port channel.
INTERFACE PORT-CHANNEL mode
show config

Example of Error Due to an Attempt to Congure an Interface that is Part of a 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 EXEC Privilege mode, as shown in the following example.
Dell#show int port brief
Codes: L - LACP Port-channel
LAG Mode Status Uptime Ports
1 L3 down 00:00:00 Te 0/16 (Down)
Dell#
The following example shows 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.
Dell#show int port-channel
