LOCAL MANAGEMENT

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.
