Label Description
Service ID
The value that identifies a service.
Mac Move
Indicates the administrative state of the MAC movement feature asso-
ciated with the service.
Mac Move Rate
The maximum rate at which MAC's can be re-learned in this TLS ser-
vice, before the SAP where the moving MAC was last seen is automat-
ically 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. The default rate of 10 re-learns per second corre-
sponds to 50 re-learns in a 5 second period.
Mac Move Timeout
Indicates the time in seconds to wait before a SAP that has been dis-
abled 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 disabled again,
the effective retry timeout is doubled in order to avoid thrashing.
Table Size
The maximum number of learned and static entries allowed in the
FDB.
Total Count
The current number of entries (both learned and static) in the FDB of
this service.
Learned Count
The current number of learned entries in the FDB of this service.
Static Count
The current number of static entries in the FDB of this service.
Remote Age
The number of seconds used to age out FDB entries learned on an SDP.
These entries correspond to MAC addresses learned on remote SAPs.
Local Age
The seconds used to age out FDB entries learned on local SAPs.
High WaterMark

alarm is raised by the agent.
Low WaterMark
The utilization of the FDB table of this service at which a ‘table full’
alarm is cleared by the agent.
Mac Learning
Specifies whether the MAC learning process is enabled in this service.
Discard Unknown
Specifies whether frames received with an unknown destination MAC
