Verifying Configuration and Performance
ExtremeWare XOS 10.1 Concepts Guide 89
You can change the QoS profile assignment for all 64 code points using the following command:
configure diffserv examination code-point <code-point> qosprofile <qosprofile>
Once assigned, the rest of the switches in the network prioritize the packet using the characteristics
specified by the QoS profile.
To verify the DiffServ configuration, use the following command:
show ports {<port_list>} qosmonitor
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 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 that handles incoming traffic from network 10.1.2.x, follow these steps:
1 Configure parameters of the QoS profile QP3:
configure qp3 min 10 max 100
2 Configure the switch so that other switches can signal class of service that this switch should
observe:
enable diffserv examination
Physical Groupings
A source port traffic grouping implies that any traffic sourced from this physical port uses the indicated
QoS profile when the traffic is transmitted out to any other port. To configure a source port traffic
grouping, use the following command:
configure ports <port_list> qosprofile <qosprofile>
In the following modular switch example, all traffic sourced from slot 5 port 7 uses the QoS profile
named qp3 when being transmitted.
configure ports 5:7 qosprofile qp3
Verifying Physical Groupings
To verify settings on ports, use the following command:
show ports {<port_list>} information {detail}
The same information is also available for ports using the following command:
show ports {<port_list>} qosmonitor
Verifying Configuration and Performance
After you have created QoS policies that manage the traffic through the switch, you can use the QoS
monitor to determine whether the application performance meets your expectations.
