mac-populate
Syntax mac-populate service-id mac ieee-address [flood] [age seconds] [force]
Context oam
Description
Populates the FIB with an OAM-type MAC entry indicating the node is the egress node for the MAC
address and optionally floods the OAM MAC association throughout the service.
A mac-populate installs an OAM MAC into the service FIB indicating the device is the egress node
for a particular MAC address. The MAC address can be bound to a particular SAP (the target-sap)
or can be associated with the control plane in that any data destined to the MAC address is forwarded
to the control plane (cpm). As a result, if the service on the node has neither a FIB nor an egress SAP,
then it is not allowed to initiate a mac-populate.
The MAC address that is populated in the FIBs in the provider network is given a type OAM, so that
it can be treated distinctly from regular dynamically learned or statically configured MACs. Note that
OAM MAC addresses are operational MAC addresses and are not saved in the device configuration.
An exec file can be used to define OAM MACs after system initialization.
The force option in mac-populate forces the MAC in the table to be type OAM in the case it already
exists as a dynamic, static or an OAM induced learned MAC with some other type binding.
An OAM-type MAC cannot be overwritten by dynamic learning and allows customer packets with
the MAC to either ingress or egress the network while still using the OAM MAC entry.
The flood option causes each upstream node to learn the MAC (that is, populate the local FIB with an
OAM MAC entry) and to flood the request along the data plane using the flooding domain.The
flooded mac-populate request can be sent via the data plane or the control plane. The send-control
option specifies the request be sent using the control plane. If send-control is not specified, the
request is sent using the data plane.
An age can be provided to age a particular OAM MAC using a specific interval. By default, OAM
MAC addresses are not aged and can be removed with a mac-purge or with an FDB clear operation.
When split horizon group (SHG) is configured, the flooding domain depends on which SHG the
packet originates from. The target-sap sap-id value dictates the originating SHG information.
Parameters
service service-id — The Service ID of the service to diagnose or manage.
destination ieee-address — The MAC address to be populated.
flood — Sends the OAM MAC populate to all upstream nodes.
age seconds — The age for the OAM MAC, expressed as a decimal integer.
force — Converts the MAC to an OAM MAC even if it currently another type of MAC.
