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.
