VPLS Service Configuration Commands
Page 468 7750 SR OS Services Guide
move-frequency
Syntax move-frequency frequency
no move-frequency
Context config>service>vpls>mac-move
Description This 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 rate is computed as the maximum number of re-learns allowed in a 5 second interval. For
example, the default rate of 10 relearns per second corresponds to 50 relearns in a 5 second period.
The no form of the command reverts to the default value.
Default 2 (when mac-move is enabled)
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.
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
mfib-table-high-wmark
Syntax [no] mfib-table-high-wmark high-water-mark
Context config>service>vpls
Description This command specifies the multicast FIB high watermark. When the percentage filling level of the
multicast FIB exceeds the configured value, a trap is generated and/or a log entry is added.
Parameters high-water-mark — Specifies the multicast FIB high watermark as a percentage.
