STP

You have connected an endstation directly to the switch and the endstation fails to boot correctly:
The switch has STP enabled, and the endstation is booting before the STP initialization process is
complete. Specify that STP has been disabled for that VLAN, or turn off STP for the switch ports of the
endstation and devices to which it is attempting to connect, and then reboot the endstation.
The switch keeps aging out endstation entries in the switch Forwarding Database (FDB):
Reduce the number of topology changes by disabling STP on those systems that do not use redundant
paths.
Specify that the endstation entries are static or permanent.

Debug Tracing

ExtremeWare includes a debug-tracing facility for the switch. The show debug-tracing command can be
applied to one or all VLANs, as follows:
show debug-tracing {vlan <name>}
The commands should only be used under the guidance of Extreme Networks technical
debug
personnel.

TOP Command

The command is a utility that indicates CPU utilization by process.
