C-6 A PPENDIX C: T ROUBLESHOOTING
The Switch keeps aging out endstation entries in the Switch
Forwarding Database (FDB):
Reduce the number of topology changes by disabling STP on those
Switches that do not use redundant paths.
Specify that the endstation entries are static or permanent.
Routing The Switch sees RIP updates but other routers don’t:
Ensure that the RIP transmit and receive modes are appropriate for the
environment. If other routers only use RIP Version 1, ensure the switch
is transmitting V1 updates.
