7.14.2 iMG LAN Diagnostics
In the MOD iMGs and the iMG726-BD-ON, the LAN diagnostic feature was added in release 3.7.4. In NMS release 12.0,
the NMS supports this LAN diagnostic functionality. With the NMS, the user can diagnose CPE LAN ports. This diagnosis
will detect faults in the subscriber's private network cables. The change to the GUI is a new panel that allows the user to
select any or all CPE switch ports, diagnose them, and see the results
The LAN Diagnostics Panel is added to the Triple-Play Service Management Form for the iMG. The LAN Diagnostics
belongs to the iMG/RG Diagnostics sub-tab, but it is only displayed if the iMG/RG is an iMG6x6MOD or iMG7x6MOD
CPE. Refer to the following figure.
Note: This tab is only available for the MOD-type iMG.
FIGURE 7-208 LAN Diagnostics Tab for MOD-type iMG
Initially the table displays each LAN port on the iMG and its current status.
Not all modules include a Glan interface; if the Glan interface is not present, the Glan row will be omitted from the table.
The current status consists of ID, Speed, Status (enabled/disabled), and Connected (true/false). These are polled from the
device and updated approximately every 30 seconds while the tab is displayed.
With each port is a “Test” button and a “Test Result” field. The Test buttons can be checked or unchecked to select individual
ports for diagnosis. The “All” button is a shortcut to conveniently check or uncheck all interfaces.
The selected ports will be diagnosed when the “Diagnose Interface” button at the bottom of the panel is activated. The oper-
ation will take several seconds.
Note: Testing all interfaces at once will increase the duration of the test and possibly interrupt CPE LAN
service, so normally test one interface at a time or small groups at a time rather than all interfaces at one
time.
Since CPE LAN service may be interrupted during diagnosis, user confirmation is required before the operation will be per-
formed, as shown in the following figure.
