The same information is also available for ports or VLANs using one of the following commands:
show ports <portlist> info {detail}
or
show vlan
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.
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
The QoS monitor rate screen (packets per second), does not display any results for at least five seconds.
After the rate has been displayed, it is updated each second.
NOTE
The QoS monitor can display up to four ports at a time.
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 111 for more
information.
