You can congure a port channel as you would a physical interface by enabling or conguring 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.
NOTE: Port channels can contain a mix of Ethernet interfaces, but Dell Networking OS disables the interfaces that are not the
same speed of the rst channel member in the port channel (refer to 10/100/1000 Mbps Interfaces in Port Channels).
You can add any physical interface to a port channel if the interface conguration is minimal. You can congure 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 system supports jumbo frames by default (the default maximum transmission unit (MTU) is 1554 bytes). To congure
the MTU, use 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.
When an interface is added to a port channel, Dell Networking OS 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.
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
LAG Mode Status Uptime Ports
1 L2L3 up 00:06:03 Te 1/6 (Up) *
Te 1/12 (Up)
2 L2L3 up 00:06:03 Te 1/7 (Up) *
Te 1/8 (Up)
Te 1/13 (Up)
Te 1/14 (Up)

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 interface port-channel 20
Port-channel 20 is up, line protocol is up
