Configuring Separate Voice and Data Subnets

For ease of network administration and increased scalability, network managers can configure the Cisco

Gigabit EtherSwitch EHWIC to support Cisco IP phones such that the voice and data traffic reside on

separate subnets. You should always use separate VLANs when you are able to segment the existing IP

address space of your branch office.

User priority bits in the 802.1p portion of the 802.1Q standard header are used to provide prioritization

in Ethernet switches. This is a vital component in designing Cisco AVVID networks.

The Cisco Gigabit EtherSwitch EHWIC provides the performance and intelligent services of

Cisco IOS software for branch office applications. The Cisco Gigabit EtherSwitch EHWIC can identify

user applications—such as voice or multicast video—and classify traffic with the appropriate priority

levels.

Note See Cisco AVVID QoS Design Guide for more information on how to implement end-to-end QoS as you

deploy Cisco AVVID solutions.

Beginning in EXEC mode, follow these steps to automatically configure Cisco IP phones to send voice

traffic on the voice VLAN ID (VVID) on a per-port basis (see the “Voice Traffic and VVID” section on

page 66).

SUMMARY STEPS

1. enable

2. configure terminal

3. interface type 0/slot/port

4. switchport mode trunk

5. switchport voice vlan vlan-id

6. end
