Chapter 55 Configuring a VoIP Network

Configuring VoIP on a Switch

You can configure the Cisco IP Phone 7960 access port (see Figure 55-5) to either trusted or untrusted mode.

In untrusted mode, all the traffic in the 802.1Q or 802.1p frames that are received through the access port is marked with a configured Layer 2 CoS value. The default Layer 2 CoS value is 0. The untrusted mode is the default when the phone is connected to a Cisco LAN switch.

In trusted mode, all the traffic that is received through the access port passes through the phone switch unchanged. The trusted mode is the default when the phone is not connected to a Cisco LAN switch.

The traffic in the frame types other than 802.1Q or 802.1p passes through the phone switch unchanged, regardless of the access port trust state.

Configuring QoS in the Cisco IP Phone 7960

These sections describe how to configure QoS in the Cisco IP Phone 7960:

•Setting the Phone Access Port Trust Mode, page 55-32

•Setting the Phone Access Port CoS Value, page 55-33

•Verifying the Phone Access Port QoS Configuration, page 55-33

Setting the Phone Access Port Trust Mode

To set the phone access port trust mode, perform this task in privileged mode:

Task

Command

 

 

Set the phone access port trust mode.

set port qos mod/ports...trust-ext {trusted

 

untrusted}

 

 

This example shows how to set the phone access port to the trusted mode:

Console> (enable) set port qos 3/7 trust-ext trusted

Port in the phone device connected to port 3/7 is configured to be trusted.

Console> (enable)
