Label Description
Service Id Displays the service ID.
Mac Move Rate Displays the maximum rate at which MAC's can be re-learned in
this 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 MAs.
The rate is computed as the maximum number of re-learns allowed
in a 5 second interval: for example, the default rate of 2 re-learns
per second corresponds to 10 re-learns in a 5 second period.
Mac Move Retries Displays the number of times retries are performed for re-enabling
the SAP.
Table Size Specifies the maximum number of learned and static entries
allowed in the FDB of this service.
Learned Count Displays the current number of learned entries in the FDB of this
service.
Remote Age Displays the number of seconds used to age out FDB entries
learned on an SAP. These entries correspond to MAC addresses
learned on remote SAPs.
High Watermark Displays the utilization of the FDB table of this service at which a
table full alarm will be raised by the agent.
Mac Learning Specifies whether the MAC learning process is enabled
Mac Aging Indicates whether the MAC aging process is enabled.
Mac Move Displays the administrative state of the MAC movement feature
associated with this service.
Mac Move Timeout Displays the time in seconds to wait before a SAP that has been
disabled after exceeding the maximum re-learn rate is re-enabled.
A value of zero indicates that the SAP will not be automatically re-
enabled after being disabled. If after the SAP is re-enabled it is dis-
abled again, the effective retry timeout is doubled in order to avoid
thrashing.
