Description
Displays the service ID.
Displays the associated MAC address.
Displays the administrative state of the MAC movement feature
associated with this service.
Displays a factor for the primary ports defining how many
MAC-relearn periods should be used to measure the MAC-
relearn rate.
Displays a factor for the secondary ports defining how many
MAC-relearn periods should be used to measure the MAC-
relearn 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.
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 disabled again, the effective retry timeout is doubled in order
to avoid thrashing.
Displays the number of times retries are performed for reen-
abling the SAP/SDP.
