3. Attach Policy to Outgoing Interface
ALU(config)#interface GigabitEthernet 3/1
ALU(config-if GigabitEthernet3/1)# service-policy out flow-
policy
We can verify from IPTraf, that traffic has been rate-limited to 5Mbps after
applying QoS.
PRIORITY QUEUING
Figure 54: QoS Priority Queuing Using OA-5740
Send continuous ping from Traffic Generator to Host B. On the OA5740-A,
configure QoS policy to prioritize traffic (ICMP - as given in the above example).
Generate additional traffic (IP) on the Traffic Generator. Increase the rate of this
secondary (IP) traffic to exceed line (10 Mbps) capacity. Since ICMP is given
higher precedence (by virtue of its high priority), ping will still go through even
though IP traffic is dropped.
1. Define Class-maps to Match ICMP Egress Traffic
ALU(config)#match-list icmp-traffic
ALU(config-match-list-icmp-traffic)#icmp any any
ALU(config)#class-map priority-traffic
ALU(config-class-map priority-traffic)#match any icmp-traffic
ALU(config-class-map priority-traffic)#exit
