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.
(Aruba)# configuration terminal
(Aruba) (config)# firewall voip-proxy-arp
