HP-UX IPQoS Configuration File Examples

Example 1: Premium Services Class Web Server

Example 1: Premium Services Class Web Server

This example shows a configuration file that provides differentiated service for three traffic classes:

•http (port 80)

•videosrv (assumes this exists in /etc/services on the local host)

•all (other) IPv4 traffic

####

#Sample file of a three-policy HP-UX IPQoS configuration.

#One policy is for HTTP (port 80) traffic. It is assured 45% of bandwidth, and

#is allowed to send up to 100% of bandwidth.

#Another policy is for video traffic; it is also assured 45% of bandwidth and

#is allowed to send up to 100% of bandwidth.

#The third policy is for all other IPv4 traffic. It is assured only

#a small amount of bandwidth (50Kpbs) but is allowed to send up to 100Kbps.

#Note that the policy specified for all other IPv4 traffic provides more

#reserve bandwidth (50Kbps) than would have been provided by the implicit default

#policy (5Kbps), had it not been defined.

#

#The DSCP settings are arbitrary and are only shown to illustrate syntax.
