Using LANVIEW

The DFE module uses 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 modules in the chassis. The Management Module handles all IP requests to the chassis IP address, such as, but not limited to, PING, Telnet, SNMP, HTTP. The Management Module also handles the CLI configuration sessions through the console port. So, when you plug into a DFE module COM port to configure a DFE module in the chassis, it is handled by the Management Module regardless of the DFE module COM port that you use.
