3.2.3Switch Clients

It is important to understand the concept of SmartCell ZX-250 switch client connections. A client connection is actually a connection between the VLAN and the SmartCell ZX-250 CPU; this CPU connection appears as if the switch is an end station on the VLAN. The SmartCell ZX-250 uses local clients to connect itself to the VLANs that it supports.

This is analogous to a phone company that supports a communication system. Even though the phone company maintains the circuits, a call to the phone company itself cannot be made unless the phone company has its own number and connection on its own phone system. Similarly, VLAN membership (and the reachability) of a SmartCell ZX-250 on any particular VLAN depends upon whether the SmartCell ZX-250 has a local client connection for that VLAN.

Clients are created using the command add laneclient for LAN emulation, and add ipatmclient for IP over ATM.

For example, the following command adds a switch client to the ELAN elan1:

SmartCell ZX# add laneclient
ClientNumber(0)	: 1
LanName(ELAN001)	: elan1
ServerType(LECS)	:
ServerAddress()	:
IPAddress()	: 128.213.77.95
NetMask(255.255.0.0)	:
MTU(1516)	:
SmartCell ZX#

Prior to creating this local client connection, end devices could communicate with each other through elan1, but they could not communicate with the SmartCell ZX-250.
