Step 1: Create FreedomIQ Access Control Lists (ACL)
Traffic should be matched based on configured ACLs, which must be configured prior to creating QoS maps. The
special handling instructions defined in a QoS map are applied to all packets allowed by the specified ACL. Below are
entries required to classify FreedomIQ traffic outbound and inbound and should be entered in the global configuration
mode:
ip access-list extended FIQ_VoIP_RTP_Traffic
permit udp any any range 6000 55000
ip access-list extended FIQ_VoIP_Signaling_Traffic
permit udp any any range 5060 5061
Step 2: Create a QoS Map
A QoS map is a named list defined by sequenced entries with a name and unique number. QoS maps are designed
for matched traffic that can be placed into priority, class-based, or shaped classes. They can also be used to set
DSCP and IP precedence values. Each QoS map can contain more then one match statement and more then one
action. The following QoS maps should be created for traffic egressing to the WAN interface:
Outbound
Traffic:
The following commands match the QoS map FIQ_VoIP_Traffic_Out using the ACL FIQ_VoIP_Traffic_Out and sets
IP Precedence 5:
qos map FIQ_VoIP_Traffic_Out 10
match precendence 5
bandwidth percent 50
qos map FIQ_VoIP_Traffic_Out 20
match list FIQ_VoIP_Signaling_Traffic
set af21
bandwidth percent 10
Step 3: Assign the QoS Policy to the WAN Interface
The following entry on the ethernet 0/1 interface is an example with the FIQ_VoIP_Traffic_Out policy attached:
Ethernet 0/1 interface:
qos-policy out FIQ_VoIP_Traffic_Out
