Chapter 1 Overview
Network Configuration Examples
Catalyst PoE switch ports automatically detect any Cisco pre-standard and IEEE 802.3af-compliant
powered devices that are connected. Each PoE switch port provides 15.4 W of power per port. The
powered device, such as a Cisco IP Phone, can receive redundant power when it is also connected to an
AC power source. Powered devices not connected to Catalyst PoE switches must be connected to AC
power sources to receive power.

Cisco CallManager controls call processing, routing, and Cisco IP Phone features and configuration.
Users with workstations running Cisco SoftPhone software can place, receive, and control calls from
their PCs. Using Cisco IP Phones, Cisco CallManager software, and Cisco SoftPhone software integrates
telephony and IP networks, and the IP network supports both voice and data.

With the multilayer switches providing inter-VLAN routing and other network services, the routers
focus on firewall services, Network Address Translation (NAT) services, voice-over-IP (VoIP) gateway
services, and WAN and Internet access.

Switches in the wiring closet have traditionally been only Layer 2 devices, but as network traffic profiles
evolve, switches in the wiring closet are increasingly employing multilayer services such as multicast
management and traffic classification.

In the wiring closet, each switch has IGMP snooping enabled to efficiently forward multimedia and
multicast traffic. QoS ACLs that either drop or mark nonconforming traffic based on bandwidth limits
are also configured on each switch. VLAN maps provide intra-VLAN security and prevent unauthorized
users from accessing critical pieces of the network. QoS features can limit bandwidth on a per-port or
multicast traffic. QoS ACLs that either drop or mark nonconforming traffic based on bandwidth limits
