From the above screen, select Configuration to display state and event configuration
information as well as OAM supported functions:
Loopback Testing
The IE-MultiWay 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.
