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
Step Command Syntax Command Mode Purpose
1
interface port-channel id-number
CONFIGURATION Create a port channel.
2
no shutdown
INTERFACE
PORT-CHANNEL
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).
