Medium-Sized Network Using Catalyst 3750-X and 3560-X Switches
 an
 show a configuration for a network of up to 500 employees. This network uses 
a Catalyst 3750-X-only Layer 3 switch stack or Catalyst 3560-X Layer 3 switches with high-speed 
connections to two routers. For network reliability and load-balancing, this network has HSRP enabled 
on the routers and on the switches. This ensures connectivity to the Internet, WAN, and mission-critical 
network resources in case one of the routers or switches fails. The switches are using routed uplinks for 
faster failover. They are also configured with equal-cost routing for load sharing and redundancy. (When 
the network uses Catalyst 3750-X switches, a Layer 2 switch stack can use cross-stack EtherChannel for 
load sharing.)
The switches are connected to workstations, and local servers, and IEEE 802.3af compliant and 
noncompliant powered devices (such as Cisco IP Phones). The server farm includes a call-processing 
server running Cisco CallManager software. Cisco CallManager controls call processing, routing, and 
Cisco IP Phone features and configuration. The switches are interconnected through Gigabit interfaces.
