voip-queue-delay

Last Updated : Nov 06, 2012 |
Sets the maximum queue delay for which to estimate the high priority queue size necessary to meet the queueing delay for specific VoIP codec parameters. Use no voip-queue-delay to return the maximum queue delay introduced for VoIP traffic by egress queueing to the default value of 20ms.
Prolog information
Note:
This command is not applicable for an interface on which Frame-Relay Traffic-Shaping is enabled. Instead, this command is now applicable under map-class frame-relay context, to control the specific DLCI queueing parameters.

Syntax

[no] voip-queue-delay queue_delay_ms [codec [frames-per-packet]]

Parameters

Parameter
Description
Possible Values
Default Value
queue_delay_ms
The maximum queue delay, in milliseconds, for which to estimate the high priority queue size. The queue delay is the amount of time that voice traffic is allowed to wait in the queue.

Context

interface:Serial (DS1 PPP L2-L3, DS1 PPP L2, USP PPP L2, USP PPP L2-L3), FastEthernet (L2, L2-L3) - when traffic shaping is configured, Serial (DS1 FR L2, USP FR L2) - when Frame Relay Traffic Shaping is not configured, map-class frame-relay, Dialer (L2, L2-L3)
Note:
This command is also used in Serial and WAN FastEthernet context when traffic shaping is configured.

Example

To set the maximum query delay to 30 milliseconds:
Gxxx-001(super)# voip-queue-delay 30
