QoS Monitor
The QoS monitor is a utility that monitors the hardware queues 
associated with any port(s). The QoS monitor keeps track of the 
number of frames and the frames per second that a specific queue is 
responsible for transmitting on a physical port. Two options are 
available: a real-time display, and a separate option for retrieving 
information in the background and writing it to the log.
Table10.12 describes the QoS monitor commands. For further 
command options, press the Tab key in the command line interface.
Real-Time Performance Monitoring
The real-time display scrolls through the given portlist to provide 
statistics. Screens for packet count and packets per second can be 
chosen. The particular port being monitored at that time is indicated 
by an asterisk (*) appearing after the port number in the display. 
The command for real-time viewing is:
show ports {<portlist>} qosmonitor
QoS monitor sampling is configured as follows:
•The port is monitored for 20 seconds before the switch moves  to 
the next port in the list.
Table 10.12:  QoS Monitor Commands
Command Description
disable qosmonitor Disables the QoS monitoring capability.
enable qosmonitor port [<port> | mgmt]  Enables the QoS monitoring capability on 
the switch. When no port is specified, the 
QoS monitor automatically samples all 
the ports. Error messages are logged to 
the syslog if the traffic exceeds the 
parameters of the QoS profile(s). The 
default setting is disabled.
show ports {<portlist>} qosmonitor Displays real-time QoS statistics for one 
or more ports.
