Configuration
Method
Description
"SFP B" line is held as the standby line. The “SFP B” line is
held in the LINK state for testing and line verification, but
does not actively carry user data.
When a fault is detected on the active line, all customer
traffic is switched to the “SFP B” port. Once the “A” port is
no longer in a fault condition, data is resumed on that port.
NOTE
Revertive and Non-Revertive modes can only operate on the ports with SFPs, not the
fixed copper ports.

5.3.8 Loopback Testing
The IE GIGA MC TX/SFP includes Loopback testing functionality. This feature
is selectable via iView2 within the OAM AH configuration. The menu of choices
for all ports includes:
•
Terminate/initiate
•
Process/ignore
OAM Loopback is controlled by using the “Loopback” and “Ignore Rx” control
parameters. Selecting “Initiate” from the “Loopback” control tells the client to
start a loopback process with the peer. Selecting “Process” from the “Ignore
Rx” control tells the client to process received loopback commands.
Only AH “Active” units can send a Loopback command to a remote unit. Either
Active or Passive AH units can respond to a Loopback command, but must be
configured to process these commands or they will be ignored.
