Redundancy Overview
The GT-1205A provides rapid fiber redundancy of link for highly
critical Ethernet applications. The redundant-mode supports
auto-recover function. If the destination port of a packet is link
down, it forwards the packet to the other port of the backup
pair. The following figure shows the redundant function.

Redundancy Behavior Topology
Link status auto detect and redundant on Dual ports with

same connector type.
Only Primary-Port is active at a time, the Backup-Port is
l
blocked.
While Primary-Port link fail occur, the traffic swap to Backup-
l
Port automatically.
Once the Primary-Port status back to link up, the traffic swap
l
from Backup-Port to Primary-Port.
