8.1 Labels
Label configuration We will now have a look at the labels that we will need.
We have five different classes of traffic, which means that we will need 5 labels:
1 A VoIP label for voice traffic.
2 A Management label for management traffic.
3 A Gold label for traffic comming from the Gold Group.
4 A Silver label for traffic comming from the Silver Group.
5 A Bronze label for traffic comming from the Bronze Group.
Go to the classification page and select the Labels tab.
Expert mode -> IP Router -> Classification
You will now see a list of labels which have been created, if a default configuration is
used.
VoIP label 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 TCP ack
packets will be treathed with the same priority. TOS Marking for these packets has
been disabled.
We will have to enable tos marking to meet the requirements.
Proceed as followed:
1 Select VoIP .
2 Set Marking to DSCP and set the DSCP value to ef .
This will enable TOS marking by DSCP, and set the DSCP value to ef for packets
which get this label assigned. By doing so packets with the VoIP label assigned will
be placed in the Real Time queue and will get priority over all other traffic.
