A.7.24.2 OAM Mode
The OAM in the 10/100A converter only works on fiber links. Both units on the fiber link must be CTC Union
10/100A family units. The OAM mode can be set to one of three choices: disabled, active or passive. In the OAM
scheme, the 'active' unit will provide the OAM configuration to 'passive' unit during OAM discovery phase. If both
units on the fiber link are set to 'active' mode, the one with lower MAC address will become the active node and the
higher MAC address unit will assume passive mode.
To configure, from the main menu, select <L> (Local Status and Configuration), then select the fiber port (1 or
2) <1> (Local Fiber 1 Status and Configuration). From this menu select <3> (OAM Channel A Mode) and set as
follows.
A.7.25 Link Loss Forwarding
In a simple media converter (two ports), a loss of fiber receive signal (link failure) can be used to force down
the electrical Ethernet link and visa versa. This mechanism is referred to as "Link Loss Forwarding" or "Link Fault
Pass-through".
Link Loss Forwarding (LLF) Mechanism
The FRM220-10/100AS-2 model is a four port L2 Fast Ethernet switch with two fiber and two electrical
Ethernet ports. With Link Loss Forwarding mechanism, when one Ethernet port detects a link down condition, this
media converter can be programmed to logically force down any or all of the other Ethernet ports. The settings are
done by check box in a 4x4 matrix.
