VLL SDP Commands
Note : VLL SDP commands are not supported on 7210 SAS-M devices configured in access uplink
mode.

Syntax spoke-sdp sdp-id[:vc-id] [vc-type {ether | vlan}] [no-endpoint] [create]
spoke-sdp sdp-id[:vc-id] [vc-type {ether | vlan}] endpoint endpoint-name
no spoke-sdp sdp-id[:vc-id]
Context config>service>cpipe
config>service>epipe
Description This command binds a service to an existing Service Distribution Point (SDP). A spoke SDP is
treated like the equivalent of a traditional bridge “port” where flooded traffic received on the spoke
SDP is replicated on all other “ports” (other spoke or SAPs) and not transmitted on the port it was
received.
The SDP has an operational state which determines the operational state of the SDP within the
service. For example, if the SDP is administratively or operationally down, the SDP for the service
will be down.
The SDP must already be defined in the config>service>sdp context in order to associate an SDP
with an Epipe or VPL service. If the sdp sdp-id is not already configured, an error message is
generated. If the sdp-id does exist, a binding between that sdp-id and the service is created.
SDPs must be explicitly associated and bound to a service. If an SDP is not bound to a service, no far-
end 7210 SAS M devices can participate in the service.
The no form of this command removes the SDP binding from the service. The SDP configuration is
not affected; only the binding of the SDP to a service. Once removed, no packets are forwarded to the
far-end router.
Default No sdp-id is bound to a service.
Special Cases Epipe — At most, only one sdp-id can be bound to an Epipe service. Since an Epipe is a point-to-
point service, it can have, at most, two end points. The two end points can be one SAP and one
SDP or two SAPs. Vc-switching VLLs are an exception. If the VLL is a “vc-switching” VLL,
then the two endpoints must both be SDPs.
Parameters sdp-id — The SDP identifier. Allowed values are integers in the range of 1 to 17407 for existing
SDPs.
vc-id — The virtual circuit identifier.
Values
1 — 4294967295
vc-type — This command overrides the default VC type signaled for the spoke binding to the far end
of the SDP. The VC type is a 15 bit-quantity containing a value which represents the type of VC.
The actual signaling of the VC type depends on the signaling parameter defined for the SDP. If
signaling is disabled, the vc-type command can still be used to define the dot1q value expected
by the far-end provider equipment. A change of the bindings VC type causes the binding to
