142 CHAPTER 17: IPX CONFIGURATION
Configuring IPX GNS
Get nearest server (GNS) is a type of SAP message broadcasted by SAP-enabled
NetWare clients. To the GNS requests, NetWare servers respond with GNS
messages.
If a NetWare server is available on the network segment to which the client is
connected, the server responds to its request. If no NetWare server is available on
the segment, the switch responds.
You can enable the switch to handle a SAP GNS request in one of the following
ways:
■ Respond with the information of the nearest server (the server with the
smallest hop count in the service information table on the switch).
■ Respond with the information of one server that is picked out from all the
known servers through round-robin polling.
■ Respond depending on whether SAP GNS reply is enabled on the VLAN
interface.
