Administrator Guide

speed of the port channel is 100 Mb/s. The system disables those interfaces configured with speed 1000 Mb/s
or whose speed is 1000 Mb/s as a result of auto-negotiation.
In this example, you can change the common speed of the port channel by changing its configuration so the
first enabled interface referenced in the configuration is a 1000 Mb/s speed interface. You can also change
the common speed of the port channel here by setting the speed of the TenGig 0/0 interface to 1000 Mb/s.
Configuration Tasks for Port Channel Interfaces
To configure a port channel (LAG), use the commands similar to those found in physical interfaces. By default,
no port channels are configured in the startup configuration.
These are the mandatory and optional configuration tasks:
• Creating a Port Channel (mandatory)
• Adding a Physical Interface to a Port Channel (mandatory)
• Reassigning an Interface to a New Port Channel (optional)
• Configuring 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)
Creating 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, 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 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.
