Additional Hostnames

The SunATM software supports logical interfaces in the SunATM LAN Emulation environment. Logical interfaces allow you to assign multiple IP addresses to a single LAN Emulation interface. A logical interface name consists of three parts: the device name (in the case of SunATM LAN Emulation, lane); the major number, which corresponds to the lane instance number; and the minor number, which distinguishes the logical interfaces on a single lane instance. The format of a LAN Emulation logical interface name is laneN:X, where N is the major number and X is the minor number (for example, lane0:2).

The SunATM software associates each logical interface with a unique hostname and IP address. All logical interfaces on a given physical interface are associated with the same ATM and MAC addresses.

The hostname displayed in the LAN Emulation instance menu corresponds to the minor instance 0. The additional IP Address parameter indicates if any additional hostnames are assigned to the instance. Select this parameter to modify or create additional hostnames. You must enter or modify each additional IP hostname in the same manner as other IP hostname and address pairs (see "ATM Address Formats and Variables" for more details), and associate it with a minor number between 0 and 255.
