If a MAC is defined with a static address, after that MAC was already learned by the system on a
restricted SAP, the system will bring the SAP to an operationally down state, flush the MAC and
generate a trap.
If the destination MAC address of a packet entering a restricted SAP with restrict-unprotected-dst
enabled, and if it is not a protected MAC, the packet will be discarded.
If the destination MAC address is unknown, even if the packet is entering a restricted SAP, with
restrict-unprotected-dst enabled, it will be flooded.
You can specify a static MAC in the mac-protect list. This action fails if the static MAC is defined
under a restricted SAP. If the MAC is protected first, the system does not allow it to be added as static
under a restricted SAP.
Default no restrict-unprotected-dst
vc-type
Syntax vc-type {ether | vlan}
Context config>service>pw-template
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 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 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
