ROUBLESHOOTING
VLANs, IP Addresses and default routes:
The system can have an IP address for each configured VLAN. It is only necessary to
have an IP address associated with a VLAN if you intend to manage (Telnet, SNMP,
ping) through that VLAN. 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 BlackDiamond 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.
