Configuring ISDN Call Destinations 131
20. Check the NCP Spoofing .
Default: Disabled
Options: Enabled, Disabled
NCP Spoofing prevents the ISDN transmission of "get directory
path" and "end of job" requests (NCP request type 2222, trans-
ported over IPX packet type 17) often issued in conjunction with
a File Open box in any Windows, Windows for Workgroups or
Windows 95 application such as Word for Windows. The number
and frequency of such NCP requests depends on whether
Micosoft´s or Novell´s NetWare Requester is used.
When NCP Spoofing is disabled, all NCP requests type 2222 are
transmitted over ISDN to all remote servers this client has drive
mappings on.
21. Check the LSP Hello Spoofing .
When NLSP is used over ISDN links, the protocol regularly
sends out so-called LSP Hello Packets (default: every 20 seconds,
maximum: every 600 seconds). The interval in which these
packets are sent can be configured via the "NLSP Convergence
Rate Configuration" menu (parameter "Non-Broadcast Hello
Interval").
LSP Hello Spoofing is provided to confirm WAN LSP Hello
packets locally on the NetWare MultiProtocol Router for ISDN
for each interface. This avoids frequent call set-ups over ISDN
and thus saves connection charges.
Default: Enabled
Options: Enabled, Disabled
When LSP Hello Spoofing is enabled, LSP Hello Packets are
confirmed locally on the NetWare MultiProtocol Router for ISDN
and are not transmitted over ISDN.
If it is disabled, ISDN connections to remote sites would be set
up over this interface each time the router creates LSP Hello
Packets.
22. Check SNMP Over IPX Filter .
Many network management systems/applications use SNMP to
gather network information.
