Fault Monitoring & Activating Backup Link
422B
The ring master monitors the network continuously. As any fault is reported, the master activates (enable) the
backup link in standby state immediately to recover the communication channel and keep the network
operating. The fault may be ring cable disconnection as shown in the left figure below:
423B
From standby state, the backup link enters into backup state. Other possible faults could be a switch failed due
to function failure or power problem as shown in the above right figure.
424B
The redundant ring function can support not only one fault case but also multiple faults cases at the same time
and give much faster response time than typical Spanning Tree Protocol. Other faults happening outside this
scope is beyond the capability of the switch.
Repairing the Network & Standby Recovery
425B
When the backup link is activated to support continuous network operation, the failed section in the ring is
blocked and isolated for physical examination and repairing by network administration people. After the failure
is repaired, the ring master monitors the health of the ring until all elements and whole network are verified to
recover back to normal condition. The ring can enter into standby state (on guard) again.
426B
The switch provides a user friendly management interface to configure the ring network. It also provides a
helpful function to examine the status of all configured rings.
Important Notes for Applications
1.
427B
One switch can support up to four AMR rings.
2.
428B

3.
429B
A switched port can not be configured as AMR ring port and RSTP port at the same time.
4.
430B
One switch can support both AMR and RSTP concurrently via different ports.
5.
431B
The AMR function is not compatible with other similar functions available in different brands of switches.
