Catalyst 4224 Access Gateway Switch Software Configuration Guide

The following example shows how to configure separate subnets for voice and
data on the Catalyst 4224:
interface FastEthernet5/1
description DOT1Q port to IP Phone
switchport access vlan 50
switchport voice vlan 150
spanning-tree portfast (See Note below)
interface Vlan 150
description voice vlan
ip address 10.150.1.1 255.255.255.0
ip helper-address 172.20.73.14 (See Note below)
interface Vlan 50
description data vlan
ip address 10.50.1.1 255.255.255.0
This configuration instructs the IP phone to generate a packet with an 802.1Q
VLAN ID of 150 with an 802.1p value of 5 (default for voice bearer traffic).
The portfast command is only supported on nontrunk ports.
In a centralized Cisco CallManager deployment model, the DHCP server
might be located across the WAN link. If so, an ip helper-address command
pointing to the DHCP server should be included on the voice VLAN interface
for the IP phone. This is done to obtain its IP address as well as the address of
the TFTP server required for its configuration.
Be aware that Cisco IOS supports a DHCP server function. If this function is
used, the Catalyst 4224 serves as a local DHCP server and a helper address
would not be required.
Configuring inter-VLAN routing is identical to the configuration on a Catalyst
6000 with an MSFC. Configuring an interface for WAN routing is consistent with
other Cisco IOS platforms.
