The Configuration Server List window shows a list of configuration servers as seen by the various LANE components in the ATM-VLAN. Configuration server addresses are typically configured on ATM switches so that when an edge device (client, LE server, or configuration server) is connected to a switch, it can exchange the configuration server address through ILMI and then contact the configuration server for the information it needs to join the ATM-VLAN. The configuration server list also serves as the criterion for deciding between the master and backup configuration server.

Step 2 Select a LANE component from the ATM-VLAN topology window.
Step 3 Select Diagnosis>Config Server Addresses.
