Configuration Task List for Port Channel Interfaces

To configure a port channel (LAG), you use the commands similar to those found in physical interfaces.

By default, no port channels are configured in the startup configuration.

• Create a port channel (mandatory)

• Add a Physical Interface to a Port Channel (mandatory)

• Reassign an Interface to a New Port Channel (optional)

• Configure the Minimum oper up Links in a Port Channel (LAG) (optional)

• Add or Remove a Port Channel from a VLAN (optional)

• Assign an IP Address to a Port Channel (optional)

• Delete or Disable a Port Channel (optional)

Create a Port Channel

You can create up to 128 port channels with 16 port members per group on an MXL Switch.

To configure a port channel, follow these steps, starting in CONFIGURATION mode:

The port channel is now enabled and you can place the port channel in Layer 2 or Layer 3 mode. To place

the port channel in Layer 2 mode or configure an IP address to place the port channel in Layer 3 mode, use

the

switchport command.

You can configure a port channel as you would a physical interface by enabling or configuring protocols or

assigning access control lists.

Add a Physical Interface to a Port Channel

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

Ensure that the port channel is active.

Note: Port channels can contain a mix of 100/1000/10000 Ethernet interfaces and 10 Gigabit Ethernet

interfaces, but FTOS disables the interfaces that are not the same speed of the first channel member in the

port channel (see 100/1000/10000 Mbps Interfaces in Port Channels).
