Cisco CATALYST 2960 - Small to Medium-Sized Network Using Catalyst 2960, 2960-S and 2960-C Switches; Figure 1-4 shows a configuration for a network of up to 500 employees. This network uses a switch stack with high-speed connections to two routers. This ensures connectivity to the Internet, WAN, and mission-critical network resources if one of the routers fails. The switch stack uses cross-stack EtherChannel for loading sharing.; This network uses VLANs to logically segment the network into well-defined broadcast groups and for security management. Data and multimedia traffic are configured on the same VLAN. Voice traffic from the Cisco IP Phones are configured on separate VVIDs. If data, multimedia, and voice traffic are assigned to the same VLAN, only one VLAN can be configured per wiring closet.; When an end station in one VLAN needs to communicate with an end station in another VLAN, a router or Layer 3 switch routes the traffic to the destination VLAN. In this network, the routers are providing inter-VLAN routing. VLAN access control lists (VLAN maps) on the stack provide intra-VLAN security and prevent unauthorized users from accessing critical areas of the network.
