Loopbacks
The
Loopbacks
sub-menu enables you to initiate a loopback for diagnostic
purposes. Selecting
Loopbacks
enters a sub-menu with the following items:
•
Aggregate
•
Port-1
•
Port-2
•
Port-3
•
Port-4
When you chose an interface (aggregate, or one of the ports), the following
loopback types can be chosen:
•
No Loop –
This option terminates the current loopback operation.
•
Bi-directional –
This option provides a loopback both toward:
•
the user port and aggregate on a port module.
•
the aggregate port and the multiplexer/demultiplexer (mux/
demux) circuitry on an aggregate module.
•
Internal
- This option provides a loopback toward:
•
the aggregate on a port module.
•
the multiplexer/demultiplexer (mux/demux) circuitry on an
aggregate module.
•
External
- This option provides a loopback toward:
•
the user port on a port module.
•
the aggregate port on an aggregate module.
