DiffServ Example
In this example, we use DiffServ to signal a class of service throughput and assign any traffic
coming from network 10.1.2.x with a specific DSCP. This allows all other network switches to
send and observe the DSCP instead of repeating the same QoS configuration on every
network switch.
To configure the switch:
1. Using ACLs, assign a traffic grouping for traffic from network 10.1.2.x to QP3:
configure access-list qp3sub any
The following is a sample policy file example:
#filename: qp3sub.pol
entry QP3-subnet {
if {
source-address 10.1.2.0/24
} then {
Qosprofile qp3;
replace-dscp;
}
2. Configure the switch so that other switches can signal calls of service that this switch should
observe by entering the following:
enable diffserv examination ports all
