The no form of this command disables MAC move.
move-frequency
Syntax move-frequency frequency
no move-frequency
Context config>service>vpls>mac-move
Description This command indicates the maximum rate at which MAC's can be re-learned in the VPLS service,
before the SAP where the moving MAC was last seen is automatically disabled in order to protect the
system against undetected loops or duplicate MAC's.
The no form of the command reverts to the default value.
Default 2 (when mac-move is enabled). For example, 10 relearns in a 5 second period.
Parameters frequency — Specifies the rate, in 5-second intervals for the maximum number of relearns.
Values 1 — 100
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
