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 first 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 configuration is minimal. You can configure 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 flow 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
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, 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
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

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.
