EPIPE services this command is not required. See the command ais-enable under epipe>sap>eth-
cfm>ais-enable for more details. This works in conjunction with the tunnel-fault accept on the
individual SAPs. Both must be set to accept to react to the tunnel MEP state. By default the service
level command is “ignore” and the sap level command is “accept”. This means simply changing the
service level command to “accept” will enable the feature for all SAPs. This is not required for EPIPE
services that only wish to generate AIS on failure.
Parameters accept — Share fate with the facility tunnel MEP
ignore — Do not share fate with the facility tunnel MEP
Default ignore (Service Level)
accept (SAP Level for EPIPE and VPLS)
limit-mac-move
Syntax limit-mac-move [blockable | non-blockable]
no limit-mac-move
Context config>service>vpls>spoke-sdp
config>service>vpls>sap
Description This command indicates whether or not the mac-move agent, when enabled using
config>service>vpls>mac-move or config>service>epipe>mac-move, will limit the MAC re-learn
(move) rate on this SAP.
Default blockable
Parameters blockable — The agent will monitor the MAC re-learn rate on the SAP, and it will block it when the
re-learn rate is exceeded.
non-blockable — When specified, this SAP will not be blocked, and another blockable SAP will be
blocked instead.
mac-pinning
Syntax [no] mac-pinning
Context config>service>vpls>sap
config>service>vpls>spoke-sdp
config>service>vpls>mesh-sdp
config>service>vpls>endpoint
config>service>pw-template
Description
This command disables re-learning of MAC addresses on other mesh SDPs within the VPLS.
The MAC address remains attached to a given Mesh for duration of its age-timer.
The age of the MAC address entry in the FIB is set by the age timer. If mac-aging is disabled on a
given VPLS service, any MAC address learned on a mesh with mac-pinning enabled remains in
the FIB on this mesh forever. Every event that otherwise results in re-learning is logged
(MAC address; original - mesh SDP; new - mesh SDP).
