7. From the Link Action menu, specify the following actions that must occur on the
downstream interfaces in the group when all upstream interfaces in the group are
down:
• Link Down: When all upstream interfaces in the group are down, all downstream
interfaces in the group are brought down too. When any of the upstream interfaces
in the group are up, all downstream interfaces in the group are brought up too.
• Link Up: When all upstream interfaces in the group are down, all downstream
interfaces in the group are brought up. When any of the upstream interfaces in
the group are up, all downstream interfaces in the group are brought down.
8. Click the Apply button.
Your settings are saved.

Configure or display upstream and downstream interfaces
for a link dependency group
In a link dependency group, if you add downstream interfaces to the group, the interfaces
are brought down until you add one or more upstream interfaces to the group. Then,
the link state of the downstream interfaces is determined by the link state of the upstream
interfaces and the action that you configure for the group. We recommend that you first
configure the upstream interfaces and then configure the downstream interfaces.
In one link dependency group, an interface can either be a member of the upstream
list or the downstream list, bot not both.
