Note 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 SmartCell 6A000 switch that is connected through an IISP 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 IISP route to communicate with the ARP server and the other VLAN members.
5.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
6.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.
7.To make certain that all end devices are registered with the ARP server, you can inspect the switch's ARP table using theshow 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 |
ClientNumber(ALL) | : |
IP/ATM Server 1 ARP | Table |
IP Address | ATM Address |

3.1.1ATM Addressing for IP over ATM
The SmartCell 6A000 uses a default form for ATM addresses in IP over ATM. The default format is constructed as follows:
netprefix + two zero bytes + IP address of the device (in hex) + a trailing zero byte
Where the netprefix is constructed from
39 + nine zero bytes + the last three bytes of the device's MAC address
For instance, if the switch MAC address is 00:20:D4:14:41:80 and its client IP address is the one used in the example in step 2, then the
39:00:00:00:00:00:00:00:00:00:14:41:80:00:00:5A:01:01:01:00
Where
•39:00:00:00:00:00:00:00:00:00:14:41:80 = netprefix
•00:00 = two trailing zeros
