Verifying Configuration and Performance
Once 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.
QoS Monitor
The QoS monitor is a utility that monitors the incoming packets on a port or ports. The QoS monitor
keeps track of the number of frames and the frames per second, sorted by 802.1p value, on each
monitored port.
Real-Time Performance Monitoring
The real-time display scrolls through the given portlist to provide statistics. You can choose screens for
packet count and packets per second.
The view real-time switch per-port performance, use the following command:
show ports {<portlist>} qosmonitor
On a stacked set of switches, this feature is only available on local ports. To view the QoS of a member
switch, use the console.
The QoS monitor rate screen (packets per second), does not display any results for at least five seconds.
Once the rate is displayed, it is updated each second.
NOTE
On the Summit 200-24, the QoS monitor can display up to four ports at a time. The Summit-200-48
does not support the QoS monitor.
NOTE
The QoS monitor displays the statistics of incoming packets. The real-time display corresponds to the
802.1p values of the incoming packets. Any priority changes within the switch are not reflected in the
display.
NOTE
The QoS monitor requires one access mask until it exits. See “Maximum Entries” on page 119 for more
information.
Displaying QoS Profile Information
The QoS monitor can also be used to verify the QoS configuration and monitor the use of the QoS
policies that are in place. To display QoS information on the switch, use the following command:
show qosprofile <qosprofile>
Displayed information includes:
• QoS profile name
