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.
The real-time display scrolls through the given
portlist
to provide
statistics. 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 as follows:
show ports {<portlist>} qosmonitor
