LOCAL MANAGEMENT
4-13
ABRP locates the problem and corrects it, the MicroMMAC-T generates 
traps to provide the network’s designated remote management station with 
information regarding the incident, including:
The beaconing device’s address
The address of the beaconing device’s Nearest Active Upstream 
Neighbor (NAUN)
The beacon type
The port(s) and/or modules left in bypass
The duration of the beaconing condition
NOTE: To prevent users from re-inserting a faulty station that could bring 
the network down, all objects identified as faulty and disabled by ABRP 
will remain disabled until a network manager repairs the fault and 
re-enables the object. 
The MicroMMAC-T provides the following ABRP management fields:
Beacon Recovery 
Number of Retries
Retry Interval
The Beacon Recovery field indicates the current status of the ABRP at the 
device. The ABRP occurs for the MicroMMAC-T ports and STH ports 
under MicroMMAC-T control only. ENABLED is the default setting in 
this field and indicates that the ABRP is currently active at the device; 
DISABLED indicates that the ABRP is inactive at the device.
The Number of Retries field displays and lets you modify the number of 
times you want the MicroMMAC-T to try to re-enable a disabled port from 
which a beaconing condition was detected. The default number of retries 
is 4. You can enter values from the range specified in the parentheses 
(000-100, 999: infinite). 
The Retry Interval field displays and lets you modify the time delay (in 
increments of 7 seconds) between ring port retry attempts. The default 
setting is 21.
