••Enter the show client command to make sure the client is operational and to obtain the 20-byte ATM address of the ARP server. For instance, if you used the client number (client 1) from the example in step 2, enter the following command.

SmartCell ZX # show client 1

T• Physically connect your end nodes and edge devices to the ZX-250 ports.

2p›F Your end nodes do not need to be physically attached to the switch that contains the ARP server. For example, an end station is connected to a ZX-250 switch that is connected through a route to the switch containing the ARP server . No special configuration is needed for this end station to participate in the VLAN because the end station automatically finds its path across the route to the ARP server and the other VLAN members.

Q• Configure the ATM interface or adapter for end nodes and edge devices. Typically, configuration

consists of designating IP over ATM as the protocol, assigning the device an IP address, and specifying the 20-byte ATM address of the ARP server (the switch’s client address). For details on the SmartCell ZX-250 automatic addressing scheme for IP over ATM, see Section 3.1.1.

–•As your end devices are configured and started, they register with the ARP server. You can test whether your IP over ATM VLAN is functional by pinging from one end device to another.

To make certain that all end devices are registered with the ARP server, you can inspect the switch’s ARP table using the show ipatmarp command. For example, if three end devices with IP addresses 90.1.1.2, 90.1.1.3, and 90.1.1.4 are added to the VLAN, the following ARP table entries should exist:

SmartCell ZX # show ipatmarp
