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:
Q
LMA terminal connected by serial line to the local management
terminal port on the host CELLplex 7000 switch.
terminal port on the host CELLplex 7000 switch.
Q
Telnet over the network via IP connectivity to host CELLplex 7000
switch from a PC or a work station connected in-band.

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

Fast Ethernet
Backbone
Figure 1-5 shows the 7600 Card used in a Fast Ethernet backbone where
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.
