config>service>vpls>mac-move>seocndary-ports
Description This command defines a factor defining how many mac-relearn measurement periods can be used to
measure mac-relearn rate. The rate must be exceeded during the defined number of consecutive
periods before the corresponding port is blocked by the mac-move feature. The cumulative-factor of
primary ports must be higher than cumulative-factor of secondary ports.
Default 2 — secondary ports
3 — primary ports
Parameters factor — Specifies the factor defining the number of mac-relearn measurement periods can be used to
measure mac-relearn rate.
Values 2 — 10
secondary-ports
Syntax secondary-ports
Context config>service>vpls>mac-move
Description This command opens configuration context for defining secondary vpls-ports. VPLS ports that were
declared as primary prior to the execution of this command will be moved from primary port-level to
secondary port-level. Changing a port to the tertiary level can only be done by first removing it from
the primary port-level.
retry-timeout
Syntax retry-timeout timeout
no retry-timeout
Context config>service>vpls>mac-move
Description This indicates the time in seconds to wait before a SAP that has been disabled after exceeding the
maximum relearn rate is reenabled.
It is recommended that the retry-timeout value is larger or equal to 5s * cumulative factor of the
highest priority port so that the sequential order of port blocking will not be disturbed by re-
initializing lower priority ports.
A zero value indicates that the SAP will not be automatically re-enabled after being disabled.
If, after the SAP is reenabled it is disabled again, the effective retry timeout is doubled in order to
avoid thrashing.
The no form of the command reverts to the default value.
Default 10 (when mac-move is enabled)
Parameters timeout — Specifies the time, in seconds, to wait before a SAP that has been disabled after exceeding
the maximum relearn rate is reenabled.
Values 0 — 120
