M4300 Intelligent Edge Series Fully Managed Stackable Switches Link Dependency Commands Link dependency allows the link status of specified ports to be dependent on the link status of one port or many ports. Consequently, if a port on which other ports depend loses a link, the dependent ports either become administratively disabled and are brought down or become administratively enabled and are brought up. link state group Use this command to indicate if the downstream interfaces of a specified group must mirror or invert the status of the upstream interfaces. The default configuration for a group is down. That is, the downstream interfaces mirror the upstream link status by going down when all upstream interfaces are down. Specifying the up keyword allows the downstream interfaces to come up when all upstream interfaces are down. Default Format Mode down link state group group-id action {up | down} Global Config link state group downstream Use this command to add a group of interfaces to the downstream interface list. Adding an interface to a downstream list brings the interface down until an upstream interface is added to the group. The link status then follows the interface that is specified in the link state group upstream command. To prevent interfaces from being brought down, enter the link state group upstream command before you enter the link state group downstream command. Format Mode link state group group-id downstream Interface Config no link state group downstream Use this command to remove a group of interfaces from the downstream list.
