Examples:
To add an entry in the QoS classification table matching IP packets with DSCP range 10-15 and assign
these to the VoIP Audio QoS Group:
# ip mfc mask 0 3 0 1 +dscp 10 15
To add an entry in the QoS classification table matching protocol type 7 and assign this to the VoIP
Audio QoS Group:
# ip mfc mask 0 3 1 +prot 1 7
To add one more classification criteria for the same entry (e.g., destination address):
# ip mfc mask 0 3 1 +dst 10.10.22.0 255.255.255.0
To delete one classification criteria from an entry of the QoS classification table:
# ip mfc mask 0 3 1 –prot
To delete the whole entry from the QoS classification table:
# ip mfc mask 0 3 0 –all
To add a new entry for classifying VoIP Audio traffic:
# ip mfc mask 0 1 1 +src 10.10.10.1 255.255.255.255 +dscp 10 15
To add a new entry for classifying VoIP Signaling:
# ip mfc mask 0 4 2 +src 10.10.10.1 255.255.255.255
To view the current QoS configuration:

11.2 Configuring the VSAT for VoIP
There are two QoS alternatives for the VoIP PHB group:
1. All VoIP traffic is mapped to QoS group 1
2. VoIP audio is mapped to QoS group 1 and VoIP signaling is mapped to QoS group 2
The second option will protect the VoIP signaling from fluctuations in the VoIP audio traffic. However,
to use this option, the VSAT‘s QoS classification must be able to distinguish between VoIP signaling and
VoIP audio in order to separate them into different QoS groups.
11.3 Configuring the VSAT for Video (ViC)
The following QoS alternatives are available for the ViC PHB group:
1. All ViC traffic is mapped to QoS group 3.
2. ViC video is mapped to QoS group 3 and ViC audio + signaling is mapped to QoS group 4.
