Traffic management is required to ensure high quality voice and video calls 

when voice, video, and data traffic share the same WAN link.  Voice and video 
traffic must be prioritized for transmission over data traffic to meet the 

stringent jitter, latency and packet loss requirements for high quality voice and 

video.  The 4300T:

• Automatically prioritizes voice and video traffic over data traffic to ensure 

high quality voice and video calls.

• Maximizes WAN link utilization by allowing data traffic to burst up to full 

line rate in the absence of voice and video calls.

Allow Hostwise 
UDP (IP-Port)

Allows all traffic matching 
the specified UDP port 
numbers and the 
specified source IP 
addresses

*Multiple entries are separated by a space

*Port are specified using a - character.  For example:  
192.168.3.1-23 for Telnet.

*Port ranges are specified using a : character.  For 
example:  192.168.3.1-23:50 means port 23 through 50

*Classful IP addresses are assumed by default.  For 
example: 192.168.3.1 uses a class c mask.  Subnets can 
be specified using the / notation.  E.g. 192.168.3.1/24
