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>spoke-sdp
config>service>vpls>mesh-sdp
config>service>vpls>sap
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).
Default MAC pinning is not enabled by default.
max-nbr-mac-addr
Syntax max-nbr-mac-addr table-size
no max-nbr-mac-addr
Context config>service>vpls>sap
config>service>vpls>spoke-sdp
config>service>vpls>endpoint
config>service>pw-template
Description This command specifies the maximum number of FDB entries for both learned and static MAC
addresses for this SAP, spoke SDP or endpoint.
When the configured limit has been reached, and discard-unknown-source has been enabled for this
SAP or spoke SDP (see discard-unknown-source on page 409), packets with unknown source MAC
addresses will be discarded.
The no form of the command restores the global MAC learning limitations for the SAP or spoke SDP.
Default no max-nbr-mac-addr
Parameters table-size — Specifies the maximum number of learned and static entries allowed in the FDB of this
service.
Values 1 — 30719
