Troubleshooting
This chapter provides information concerning the following:
Unless otherwise noted, the following information applies to all NAC Controller PEPs.
Using LANVIEW
The NAC Controller PEPs use a built‐in visual diagnostic and status monitoring system called
LANVIEW. The LANVIEW LEDs (
Figure 5‐1 ) allow quick observation of the network status to aid
in diagnosing network problems.
About the Management (MGMT) LED
The MGMT LED (shown in Figure 5‐1 ) indicates that the NAC Controller PEP is serving as the
Management Module to control the management functions for the NAC Controller PEP. 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.
Viewing the Receive and Transmit Activity
On the 2S4082‐25 and 7S4280‐19 NAC Controller PEPs, 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 5‐1 ) 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.
