To perform beacon recovery, the Recovery ASIC operates in one of the following three modes:

1. MAC frame monitor:

In this mode the recovery ASIC is listening for Beacon MAC frames. This is the normal mode of operation for the Recovery ASIC.

2. Frame transmit:

In this mode the recovery ASIC can transmit Beacon Type 1 MAC frames. The Recovery ASIC enters this mode when it sees a Beacon Type 2, 3 or 4 MAC frame.

Note: A Beacon Type 1 MAC frame is used for management purposes. Beacon MAC frames from a normal ring station are type 2, 3 or 4 depending upon the fault.

3. Manual mode:

This mode is used for ring reconfiguration with 8250 repeaters and using proprietary 8250 trunk unwrapping.

Before describing the procedure used by the Recovery ASIC, to recover the beaconing conditions, lets review the ring monitor function which is implemented on the per-port switching modules.

8.9.3.2 Ring Monitor on the Per-Port Switching Module

Ring monitor is a function which is employed on each port of the active per-port switching module and the dual-fiber repeater module and is required to assist the Recovery ASIC to perform beacon recovery on these modules.

Ring monitors have the responsibility to monitor their respective port for the following:

The presence of a Beacon MAC frame

The presence of AMP/SMP (Active Monitor Present/Standby Monitor Present)
