Designating a nonfavored interface in a single-mode interface group

When you create a single-mode interface group, an interface is randomly selected to be the active interface. You can designate an interface as nonfavored so that it is not considered during the random selection of an active interface in a single-mode interface group.

About this task

The interface marked as nonfavored can become the active interface when all other interfaces in a single-mode interface group fail. Even after other interfaces come to the up state, a nonfavored interface continues to remain the active interface until it fails or until you, the system administrator, change the active interface by using the ifgrp favor command.

Step

  1. Enter the following command:
    ifgrp nofavor interface_name

    interface_name is the name of the interface you do not want to be considered during the random selection of an active interface.

    Note: The operation performed using the ifgrp nofavor command is not persistent across reboots unless the command is added to the /etc/rc file.

    Example

    Specify the interface e2 to be nonfavored with the following command:

    ifgrp nofavor e2
