discard-unknown-source
Syntax [no] discard-unknown-source
Context config>service>pw-template
Description When this command is enabled, packets received with an unknown source MAC address will be 
dropped only if the maximum number of MAC addresses have been reached. When disabled, the 
packets are forwarded based on the destination MAC addresses.
The no form of this command causes packets with an unknown source MAC addresses to be 
forwarded by destination MAC addresses.
Default no discard-unknown
limit-mac-move
Syntax limit-mac-move [blockable | non-blockable]
no limit-mac-move
Context config>service>pw-template
Description This command indicates whether or not the mac-move agent will limit the MAC re-learn (move) rate.
Default blockable
Parameters blockable  — The agent will monitor the MAC re-learn rate, and it will block it when the re-learn rate 
is exceeded.
non-blockable — When specified, a SAP will not be blocked, and another blockable SAP will be 
blocked instead.
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 
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.
