You can shut down a management VPLS without deleting the service parameters.
When a management VPLS is disabled, all associated user VPLS services are also disabled (to prevent loops). If this is not needed, un-manage the user’s VPLS service by removing them from the managed-vlan-list or moving the spoke-SDPs to another tunnel SDP.
CLI syntax:
config>service
vpls service-id
shutdown
Example:
config>service# vpls 1
config>service>vpls# shutdown
config>service>vpls# exit
