Troubleshooting
This chapter provides information concerning the following:
Unless otherwise noted, the following information applies to all DFE modules.
Using LANVIEW
The modules use a built‐in visual diagnostic and status monitoring system called LANVIEW. The
LANVIEW LEDs (
Figure 4‐1 ) allow quick observation of the network status to aid in diagnosing
network problems.
About the Management (MGMT) LED
The MGMT LED (shown in Figure 4‐1 ) indicates when the module is serving as the Management
Module to control the management functions for all DFE‐Platinum modules in the chassis. The
Management Module handles all IP requests to the chassis IP address, such as PING, Telnet,
SNMP, and HTTP. The Management Module also handles the CLI configuration sessions by
means of the console port. So, when you plug into a DFE‐Platinum module COM port to configure
a module in the chassis, it is handled by the Management Module regardless of the DFE‐Platinum
module COM port that you use.
Viewing the Receive and Transmit Activity
On the 2G4082‐25, you can view the receive and transmit activity on the RX and TX LEDs.
However, only one group of 12 ports may be viewed at a time.
To view the receive and transmit activity on a group of attached segments, press the GROUP
SELECT button (see
Figure 4‐1 ) to step to the group of interest (Groups 1 or 2). Each time the
GROUP SELECT button is pressed, the GROUP LED lights up in sequence, indicating which
group is selected. The receive and transmit activity for that group of segments is then indicated by
the RX and TX LEDs for each port.
