QoS Commands
enable qosmonitor
enable qosmonitor {port <port>}
Description
Enables the QoS monitoring capability on the switch.
Syntax Description
Default
Disabled.
Usage Guidelines
When no port is specified, the QoS monitor automatically samples all the ports and records the sampled
results. Error messages are logged to the syslog if the traffic exceeds the parameters of the QoS
profile(s).
The QoS monitor is a utility that monitors the eight hardware queues (QP1-QP8) 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.
Monitoring QoS in the background places transmit counter and any “overflow” information into the
switch log. The log notification appears if one of the queues experiences an overflow condition since the
last time it was sampled. An overflow entry indicates that a queue was over-subscribed at least
temporarily, and is useful for determining correct QoS settings and potential over-subscription issues.
Example
The following command enables the QoS monitoring capability on port 4:
enable qosmonitor port 4
