•
Catalyst 3750G multilayer Gigabit switches to enhance network reliability and load balancing for
different VLANs and subnets. Using HSRP also provides faster network convergence if any network
failure occurs. You can connect the Catalyst switches, again in a star configuration, to two
Catalyst 3750G multilayer backbone switches. If one of the backbone switches fails, the second
backbone switch preserves connectivity between the switches and network resources.

and switch stacks to interconnect groups of servers, centralizing physical security and
administration of your network. For high-speed IP forwarding at the distribution layer, connect the
switches in the access layer to multilayer switches with routing capability. The Gigabit
interconnections minimize latency in the data flow.
QoS and policing on the switches provide preferential treatment for certain data streams. They
segment traffic streams into different paths for processing. Security features on the switch ensure
rapid handling of packets.
