Quality of Service (QoS) 
Quality of service is achieved by prioritizing the SpectraLink voice 
traffic over data traffic. To prioritize the voice traffic over data traffic 
in the AP traffic queues, the “queue high” tag is used at the end of 
each ACL to prioritize the traffic matching the ACL over all other 
traffic.  In the example shown above: 
user alias svp_server svc-svp permit queue high 
alias svp_server user svc-svp permit queue high 
The traffic that matches the above two rules is prioritized over all 
other traffic. In addition, a DiffServ tag or a Dot1p tag can be 
configured at the end of each ACL to indicate the relative priority of 
the traffic to the traffic to the network. 
Example :  
user   alias svp_server svc-svp permit dot1p 4 queue 
high dot1p-priority 4 tos 4 queue high 
alias svp_server user svc-svp permit queue high dot1p-
priority 4 tos 4 queue high 
By default, the packets are not tagged. 
In addition multicast/bradcast traffic in the air can be limited by 
turning on the firewall voip-prox-arp. This command is available on 
the CLI alone.
