Typical Applications of the 7600 Card 1-5

Virtual LAN can incorporate both legacy LANs and ATM devices. Virtual LANs allow the establishment of logical workgroups, independent of physical connections, to achieve more flexible management. Using this feature, you can dynamically set up and manage workgroups composed of members from various departments or business units around the enterprise, regardless of their physical location.

Traffic Management Traffic Management optimizes use of system resources to ensure optimum control of traffic and congestion. The 7600 Card makes use of the ATM Forum Traffic Management standard to expedite traffic to Ethernet workgroup servers and server clusters by providing dynamic traffic rate shaping.

Device Management The 7600 Card can be managed in a number of ways:

QLMA terminal connected by serial line to the local management terminal port on the host CELLplex 7000 switch.

QTelnet over the network via IP connectivity to host CELLplex 7000 switch from a PC or a work station connected in-band.

QTranscend Enterprise Manager (or any other SNMP-based network management application) connected over the network to the 7600 Card’s IP.

For more information see “Connecting to a Local Management Terminal” on page 2-6 and Chapter 14.

Typical Applications The 7600 Card can be used to advantage in many different locations and

of the 7600 Card configurations. See the following two examples:

Fast Ethernet Figure 1-5 shows the 7600 Card used in a Fast Ethernet backbone where Backbone the host CELLplex 7000 is located in the data center and each floor is

served by a Super-Stack II Switch 1000. The Fast Ethernet downlink from the Switch 1000 units connect to the Fast Ethernet ports of the 7600 Card. Each 7600 Card can handle 16 Switch 1000 units.
