show dot1ad service-subscription

This command output shows all the services subscribed on the given LAN interfaces.

Format	`show dot1ad service-subscription {unit/slot/port \| all \| service-name}`
Mode	Privileged EXEC

Parameter	Description
unit/slot/port	Shows all subscriptions on the specified unit/slot/port.
all	Shows subscriptions to all services.
service-name	Shows all subscriptions to the specified service name.
e-lan \| e-line \| e-tree \| tls	These parameters define the type of traffic associated with this service instance. e-lan – A switched or general service is one in which the traffic associated with that service is forwarded based on a standard L2 switching lookup using the S-VID and destination MAC as lookups in the FDB. In LCOS SX a port can be a member of multiple E-LAN services. If a switched service is assigned to multiple UNI ports, those ports will be able to forward traffic to each other as well as to the NNI ports. The same E-LAN service can also be applied on UNI-P and UNI-S ports. e-line – The `e-line` parameter creates a point-to-point service, in which traffic is forwarded directly to the NNI port in the upstream direction and to the associated UNI port in the downstream direction. An e-line service bypasses the standard VLAN/MAC-based switching decisions, including the source MAC learning. Be default, LCOS SX does not learn traffic belonging to the e-line service. An e-line service-instance defines a point-to-point service in which only one UNI-P or UNI-S port participates. Note: It is important to note that downstream broadcast and multicast traffic will still be redirected to the associated UNI port participating in the e-line service. e-tree – The `e-tree` parameter creates a point-to-multipoint service in which the traffic associated with that service is forwarded directly to the NNI port in the upstream direction and direct to the associated UNI port(s) in the downstream direction. If an e-tree service instance is applied to multiple UNI ports, it becomes a point- to-multipoint service in which the participating user ports are still isolated from each other. Note: It is important to note that downstream broadcast, multicast, and unknown destination (DLF) traffic will still be forwarded (replicated) to all ports participating in the e-tree service. tls (Transparent LAN Service). Administrators can configure a TLS on UNI-P and UNI-S ports. A Transparent LAN service is used to connect the remote sites of a customer with C-Tag transparency. There are no match criteria for a TLS. If no TLS service is configured on an UNI-P port, all packets not matching any of the service instances configured on the ports will be dropped. If a TLS service is configured, then all packets not matching the other service instances on that port will be tagged as per the TLS definition on that port. TLS service defined by the user will be used by Untagged, Priority Tagged, and C-VLAN tagged packets which do not match any other service instances on the port. If a TLS service is configured on an UNI-S port, service VLAN tagged (including double tagged) frames that do not match other service instances on the port will be forwarded to appropriate NNI port(s) based on the S-VID associated with the service without any VLAN modification. Untagged and priority tagged packets that do not match other service instances on the port will be dropped.
