7.1 Configuring labels and rules for VoIP.
Introduction We will now have a closer look at the parameters needed to configure classification
for Voice over IP.
Since voice traffic is very sensitive to delay and jitter we would like to give our voice
traffice absolute priority over all other traffic.
The web interface The SpeedTouch™ can be configured in two way’s:
Via the command line interface (CLI)
Via the web interface (GUI)
In this chapter we willl use the GUI to configure the SpeedTouch™, at the end of this
chapter a CLI command list will be given as well.
To enter the GUI open a web browser and surf to the following webpage : http://
192.168.1.254 or http://SpeedTouch
This is the default IP address of the SpeedTouch™.
Labels Go to the classification menu by clicking:
Expert mode -> IP Router -> Classification
Select the Labels tab a list of labels which have been created, if a default
configuration is used.
In this list we can see a label named VoIP.
Packets who get this label assigned will have their internal class set to 14. This
means that these packets will be placed in the Real Time queue. The Real Time
queue is used for traffic with the highest priority. The TCP ack packets will be
treathed with the same priority. TOS Marking for these packets has been disabled.
