Note. If you change the number of log lines, the QoS log may be completely cleared. To change the log 
lines without clearing the log, set the log lines in the boot.cfg file; the log will be set to the specified 
number of lines at the next reboot.
Log Detail Level
To change the level of detail in the QoS log, use th
 command. The log level determines the 
amount of detail that will be given in the QoS log. The qos log level command is associated with the qos 
debug
 command, which determines what kind of information will be included in the log.
The default log level is 6. The range of values is 1 (lowest level of detail) to 9 (highest level of detail). For 
example:
-> qos log level 7
The log level is changed immediately but the setting is not saved in flash. To activate the change, enter the 
qos apply command. For more information about the qos apply command, see 
Note. A high log level value will impact the performance of the switch.
Forwarding Log Events 
NMS applications may query the switch for logged QoS events. Use the 
make QoS log events available to these applications in real time. For example:
-> qos forward log
To disable log forwarding, enter the following command:
-> qos no forward log
To activate the change, enter the qos apply command. For more information about the qos apply 
command, see 
.
If event forwarding is disabled, NMS applications will still be able to query the QoS software for events, 
but the events will not be sent in real time.
Forwarding Log Events to the Console
QoS log messages may be sent to the switch logging utility, which is an event logging application avail-
able on the OmniSwitch. The configuration of the switch logging utility then determines if QoS messages 
are sent to a log file in the switch’s flash file system, displayed on the switch console, and/or sent to a 
remote syslog server.
To send log events to the switch logging utility, enter the following command:
-> qos log console
To disable immediate forwarding of events to switch logging, enter the following command:
-> qos no log console
To activate the change, enter the qos apply command. For more information about the qos apply 
command, see
