Link Dependency Commands

Link dependency allows the link status of a group of interfaces to be made
dependent on the link status of other interfaces. The effect is that the link
status of a group that depends on another interface either mirrors or inverts
the link status of the depended-on interface. Circular dependencies are not
allowed. For example, if port-channel 1 in group 1 depends on port-channel 2.
Then the system will not allow the operator to configure another link
dependency group where port-channel 2 depends on port-channel 1.
Commands in this Section
This section explains the following commands:
action
Use the action command in Link Dependency mode to indicate if the link-
dependency group should mirror or invert the status of the depended-on
interfaces.
Syntax
action {down|up}
• down—Mirror the depended on interface(s) status.
• up—Invert the depended on interface(s) status.
Default Configuration
The default configuration for a group is down, i.e. the group members will
mirror the depended-on link status by going down when all depended-on
interfaces are down.
action –
