2 Ensure that the port channel is active.
INTERFACE PORT-CHANNEL mode
no shutdown
After you enable the port channel, you can place it in Layer 2 or Layer 3 mode. To place the port channel in Layer 2 mode use the
switchport command, or congure and IP address to place the port channel in Layer 3 mode.
NOTE: L3 is not supported on port extender (PE) ports or on port-channels when they have PE ports as members.
You can congure a port channel as you would a physical interface by enabling or conguring protocols or assigning access control lists.
Adding a Physical Interface to a Port Channel
The physical interfaces in a port channel can be on any line card in the chassis, but must be the same physical type.
You can add any physical interface to a port channel if the interface conguration is minimal. You can congure only the following
commands 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
: A logical port channel interface cannot have ow 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 congure
the MTU, use the mtu command from INTERFACE mode.
To view the interface’s conguration, 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.
Dell#show int port brief
