In a large network, IPX SAP broadcasts may occupy much bandwidth. Changing
IPX SAP update interval is an effective way to reduce bandwidth occupation. You
can configure IPX SAP aging interval as a value multiple times the update interval.
Follow these steps to configure IPX SAP timers:
To do...
Enter system view
Specify an IPX SAP update
interval
Specify an aging interval for
IPX SAP service information
entries
Enter interface view
Configure the maximum
length of IPX RIP updates
CAUTION:
During configuration you should make sure that all servers and routers on the
■
network have the same SAP updating interval. Otherwise, a router may
consider a working server failed.
If the service information is not updated within the aging interval, it will be
■
deleted from the service information table.
GNS (Get Nearest Server) is a SAP message, broadcasted by a SAP-enabled
NetWare client. A NetWare server will respond to the request with a Give Nearest
Server message.
If the NetWare server and the client reside in a common network, the server will
respond to the client. If no NetWare server is available on the client's network, the
connected router will respond.
You can configure a router to respond to a SAP GNS request with:
Nearest server, namely, the nearest server which has the least hops in the
■
service information table, or
All available servers in turn, namely round-robin mode.
