TOP Command
ExtremeWare 7.2e Installation and User Guide 327
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 Memory Dump
You can download the entire contents of memory through the Ethernet management port. This is used
only for troubleshooting, and should not be used without assistance from Extreme Networks technical
support.
To specify the IP address to which to transfer a dump if the system-dump option is specified in the
configuration, use the following command:
configure system-dump server <ip address>
This address is also used if no address is provided in the command. The default is 0 or “no IP”.
To set an optional timeout for the dump transfer, use the following command:
configure system-dump timeout <seconds>
The default is 0. The minimum non-zero value is 120 seconds. The minimum recommended value is 480
seconds.
To display the system-dump server IP and dump-timeout, use the following command:
show system-dump
To specify a memory dump if a task generates a software exception, use the following command:
configure sys-recovery-level [none | [all | critical] [ reboot | shutdown |
system-dump [maintenance-mode | reboot | shutdown]]]
The four options specify the action taken when the dump transfer is complete. The actions occur
whether or not the dump was successful. The
maintenance-mode option leaves the switch in whatever
state it was in before the dump.
