Conguration Tasks for Port Channel Interfaces
To congure a port channel (LAG), use the commands similar to those found in physical interfaces. By default, no port channels are
congured in the startup conguration.
These are the mandatory and optional conguration tasks:
• Creating a Port Channel (mandatory)
• Adding a Physical Interface to a Port Channel (mandatory)
• Reassigning an Interface to a New Port Channel (optional)
• Conguring the Minimum Oper Up Links in a Port Channel (optional)
• Adding or Removing a Port Channel from a VLAN (optional)
• Assigning an IP Address to a Port Channel (optional)
• Deleting or Disabling a Port Channel (optional)
• Load Balancing Through Port Channels (optional)
Creating a Port Channel
You can create up to 128 port channels with up to 16 port members per group on the platform.
To congure a port channel, use the following commands.
1 Create a port channel.
CONFIGURATION mode
interface port-channel id-number
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 or congure an IP
address to place the port channel in Layer 3 mode, use the switchport command.
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.
NOTE
: Port channels can contain a mix of Ethernet interfaces, but Dell EMC 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
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.
