HP-UX IPQoS Configuration File Examples
Example 1: Premium Services Class Web Server
Appendix B 119
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.
