ExtremeWare 7.2e Installation and User Guide 331
To change the debug tracing facility for a certain system to a specified debug level, use the following
command:
configure debug-trace <system> <level> vlan <vlan name>
Some of the debug trace systems commands can be applied to a particular VLAN, some apply to the
switch as a whole, so the
vlan
option is not available with all systems.
To display the debug tracing configuration, use the following command:
show debug-trace <system> vlan <vlan name>
Again, the
vlan
option is not available with every system.
TOP Command
The
top
command is a utility that indicates CPU utilization by process.
System Odometer
Each field replaceable component contains a system odometer counter in EEPROM. You can use the
show switch
command to see how long an individual component has been in service since it was
manufactured.
Reboot Loop Protection
If the system reboots due to a failure that remains after the reboot, it reboots when it detects the failure
again. To protect against continuous reboot loops, you can configure reboot loop protection using the
following command:
configure reboot-loop-protection threshold <time-interval> <count>
If the switch reboots the specified number of times within the specified time interval, it stops rebooting
and comes up in minimal mode. If you reboot the switch manually or
run diagnostics
commands,
the time interval and count are both reset to 0.
Minimal Mode
In minimal mode, only the CPU, NVRAM, management port, and minimal tasks are active. The
following commands are supported in minimal mode:
• reboot
• unconfigure switch all
• unconfigure switch
• use image
• use configuration
• download bootrom
