VLANs, IP Addresses and default routes:
The system can have an IP address for each configured VLAN. It is
necessary to have an IP address associated with a VLAN if you
intend to manage (Telnet, SNMP, ping) through that VLAN or route
IP traffic. You can also configure multiple default routes for the
system. The system first tries the default route with the lowest cost
metric.
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 either static or permanent for the endstation entries.
Debug Tracing
The local management software 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
debug
Intel technical personnel.
