The WAN link shown is a serial interface but could be any technology (Frame Relay, ATM,
MPLS).
Ethernet Switch 1 configuration
There are four physical connections in the example topology for Ethernet Switch 1.
1. Fa0/2 to the 3300 ICP
2. Fa0/4 to IP Phone extension 2001
3. Fa0/5 to Ethernet Switch 2
4. Fa0/24 to Router 1 port Fa0/0
In this example VLANs are being assigned to the IP phones using CDP. Configurations for each
switch interface follow (assumes no Cisco VLAN Trunking Protocol):
Figure 56: Example Network Topology
Switch# configure terminal
Switch1(config)# mls qos [sets up QOS on the switch globally]
Switch1(config)# vlan 100 [create the voice VLAN]
Switch1(config-vlan)# name VoiceVLAN [Give it a name]
Switch1(config-vlan)# exit
