link state group
Use this command to indicate if the downstream interfaces of the group should mirror or invert the
status of the upstream interfaces. The default configuration for a group is down (that is, the
downstream interfaces will mirror the upstream link status by going down when all upstream interfaces
are down). The action up option causes the downstream interfaces to be up when no upstream
interfaces are down.
Default down
Format link state group group-id action {up | down}
Mode Global Config
no link state group
Use this command to restore the link state to down for the group.
Format no link state group group-id action
Mode Global Config
link state group downstream
Use this command to add 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 specified in the upstream command. To avoid bringing down interfaces,
enter the upstream command prior to entering the downstream command.
Format
link state group group-id downstream
Mode Interface Config
no link state group downstream
Use this command to remove the selected interface from the downstream list.
Format
no link state group group-id downstream
Mode Interface Config
link state group upstream
Use this command to add interfaces to the upstream interface list. Note that an interface that is defined
as an upstream interface cannot also be defined as a downstream interface in the same link state group
or as a downstream interface in a dierent link state group, if either configuration creates a circular
dependency between groups.
Format
link state group group-id upstream
Mode Interface Config
