Configures a LAG profile for hardware support.

Syntax

profile lag { default | lag-profile-1 }

Command Default

The default LAG profile is enabled.

Parameters

default: Specifies the default LAG profile. As described in the Usage Guidelines, the maximum numbers of port-channel IDs and links per port-channel vary with device and TCAM profile.
lag-profile-1: Specifies lag-profile-1 as the LAG profile. As described in the Usage Guidelines, the maximum numbers of port-channel IDs and links per port-channel vary with device and TCAM profile.

Modes

Hardware configuration mode

Usage Guidelines

This command is supported on the Extreme 8820, SLX 9740, SLX 9640, and SLX 9540 devices only.

To view the current LAG profile, enter the show hardware profile current command.

For the new setting to take effect, you need to run the copy running-config startup-config to reload the device. Run this command during a maintenance window so that the profile changes are activated without interrupting normal network services.

This command does not support a no form. Use the profile lag default form of the command to restore the default LAG profile.
