Chapter 55 Configuring a VoIP Network

Configuring VoIP on a Switch

Default Configuration

The default setting for all ports is trust-device none.

Specifying a Cisco IP Phone as the Trust Device

To specify a Cisco IP Phone as the trust device, perform this task in privileged mode:

Task

Command

 

 

Specify a Cisco IP Phone as the trust device.

set port qos mod/ports...trust-device

 

[ciscoipphone none]

 

 

This example shows how to trust only Cisco IP phones on port 4/1:

Console> (enable) set port qos 4/1 trust-device ciscoipphone

Port 4/1 set to only trust device of type ciscoIPPhone.

Console> (enable)

This example shows how to disable the device trust on port 4/1:

Console> (enable) set port qos 4/1 trust-device none

Port 4/1 trust device feature disabled.

Console> (enable)

Verifying a Port’s Trust-Device State

To verify a port’s trust-device state, perform this task in normal mode:

Task

Command

 

 

Verify a port’s trust-device state.

show port qos [mod[/port]]

 

 

When the trusted boundary is active, the run-time trust state of the port changes depending on the presence of the phone.

Note The moment that the phone leaves the switch port, there is a slight convergence time for the port to change to the untrusted state (a maximum time of 15 seconds).

This example shows how to verify the trust-device state and trust state on port 4/1:

Console> (enable) show port qos 4/1
