Traffic Groupings
ExtremeWare XOS 11.3 Concepts Guide

To configure the switch, follow these steps:
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;
}
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
DiffServ example for the BlackDiamond 10K switch. In this example on the BlackDiamond 10K switch, we
use DiffServ to signal a class of service throughput and assign any traffic coming from network 10.1.2.x
with a specific DiffServ code point. This allows all other network switches to send and observe the
Diffserv code point instead of repeating the same QoS configuration on every network switch.
To configure the switch, follow these steps:
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
NOTE
The switch only observes the DiffServ code points if the traffic does not match the configured access list. Otherwise,
the ACL QoS setting overrides the QoS DiffServ configuration.
