To specify the <strong>de</strong>sired quality of service to be used in reaching a specified dial peer, use the req-qos<br />

dial-peer configuration command. Use the no form of this command to restore the <strong>de</strong>fault value for<br />

this command.<br />

req-qos {best-effort | controlled-load | guaranteed-<strong>de</strong>lay}<br />

no req-qos<br />

Syntax Description<br />

best-effort Indicates that Resource Reservation Protocol (RSVP) makes no<br />

bandwidth reservation.<br />

controlled-load Indicates that RSVP guarantees a single level of preferential service,<br />

presumed to correlate to a <strong>de</strong>lay boundary. The controlled load service<br />

uses admission (or capacity) control to assure that preferential service is<br />

received even when the bandwidth is overloa<strong>de</strong>d.<br />

guaranteed-<strong>de</strong>lay Indicates that RSVP reserves bandwidth and guarantees a minimum bit<br />

rate and preferential queuing if the bandwidth reserved is not excee<strong>de</strong>d.<br />

Default<br />

The <strong>de</strong>fault value for this command is best-effort. The no form of this command restores the <strong>de</strong>fault<br />

value.<br />

Dial-peer configuration<br />

Usage Gui<strong>de</strong>lines<br />

This command first appeared in Cisco IOS Release 11.3(1)T.<br />

Use the req-qos command to request a specific quality of service to be used in reaching a dial peer.<br />

Like acc-qos, when you enter this command, the Cisco IOS software reserves a certain amount of<br />

bandwidth so that the selected quality of service can be provi<strong>de</strong>d. Cisco IOS software uses Resource<br />

Reservation Protocol (RSVP) to request quality of service guarantees from the network.<br />

This command is applicable only to VoIP peers.<br />

Example<br />

The following example configures guaranteed-<strong>de</strong>lay as the <strong>de</strong>sired (requested) quality of service to<br />

a dial peer:<br />

dial-peer <strong>voice</strong> 10 voip<br />

req-qos guaranteed-<strong>de</strong>lay<br />
