Supported NetWare Protocols
On the NonStop system, the SAP table is maintained by the IPXPROTO process. The
SCF command STATUS SERV returns information about the SAP table maintained by
the IPXPROTO process.
Server applications use the SAP protocol to perform the following:
•
Add an entry for the service in the SAP table maintained by the IPXPROTO
process. The entry is then propagated to other NetWare servers by the IPXPROTO
process by broadcasts every 60 seconds. Clients can view the advertised services
on the network.
•
Delete an entry for the service in the SAP table.
•
Display servers in the SAP table that are of a specified service type.
Each SAP table entry contains the following information:
Clients can query the SAP tables for available services and obtain the addresses of the
servers that are offering those services. A client might look for a specific server or for
all servers of the same type.
Server Name a string of up to 48 characters. The server name must be unique
within the entire NetWare internetwork.
Note. For NonStop server applications, HP recommends that the NonStop system name and
the Guardian process name be used for the server name, for example, DUNCAN.$ODBC1. This
convention ensures that the server name is unique in the NetWare internetwork.
Server Type a unique number assigned to a class of servers, such as the
NetWare file server class, various print server classes, and so
on. HP has reserved a range of server-type numbers for
NonStop services such as Telserv and ODBC servers. Table 2-4
lists the server types.
Internet Address contains the IPX address of the server.
Hops to Server contains the number of routers that must be passed to reach the
server.
Time Since
Changed
removes entries for a server that started but has subsequently
stopped advertising.
