SDP Commands
Page 102 7210 SAS-X, R6 OS Services Guide
Description This command overrides the default VC type signaled for the binding to the far end 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
vctype 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 signal the new VC type to the far end when
signaling is enabled.
VC types are derived according to IETF draft-martini-l2circuit-trans-mpls.
• The VC type value for Ethernet is 0x0005.
• The VC type value for an Ethernet VLAN is 0x0004.
Parameters ether — Defines the VC type as Ethernet. The ethernet and vlan keywords are mutually exclusive.
When the VC type is not defined then the default is Ethernet for spoke SDP bindings. Defining
Ethernet is the same as executing no vc-type and restores the default VC type for the spoke SDP
binding. (hex 5)
vlan — Defines the VC type as VLAN. The ethernet and vlan keywords are mutually exclusive.
When the VC type is not defined then the default is Ethernet for spoke SDP bindings.
vlan-vc-tag
Syntax vlan-vc-tag 0..4094
no vlan-vc-tag [0..4094]
Context config>service>pw-template
Description This command specifies an explicit dot1q value used when encapsulating to the SDP far end. When
signaling is enabled between the near and far end, the configured dot1q tag can be overridden by a
received TLV specifying the dot1q value expected by the far end. This signaled value must be stored
as the remote signaled dot1q value for the binding. The provisioned local dot1q tag must be stored as
the administrative dot1q value for the binding.
When the dot1q tag is not defined, the default value of zero is stored as the administrative dot1q
value. Setting the value to zero is equivalent to not specifying the value.
The no form of this command disables the command
Default no vlan-vc-tag
Parameters 0..4094 — Specifies a valid VLAN identifier to bind an 802.1Q VLAN tag ID.
adv-mtu-override
Syntax [no] adv-mtu-override
Context config>service>sdp
Description This command overrides the advertised VC-type MTU of all spoke-sdps of Layer 2 services using
this SDP-ID. When enabled, the router signals a VC MTU equal to the service MTU, which includes
