R56 Description of the menu options
Different SAP types are stored in the table. The server name, the applicable network, the
server MAC address (000000000001 for internal server networks), the socket number and
information on the location of the server must be read.
LAN-filter-table Entries in the LAN filter table make it possible to exclude specific service information
ranges of a Novell network from being included in the SAP table and therefore to make
better use of the resources of the IPX router. This also prevents unwanted connections
from being established by these SAPs (services).
None of the service information located within a range of filters entered in the LAN filter
table is transferred by the local network to the IPX router's SAP table. They are also not
transferred to the remote station of the IPX router and therefore are also not available
there.
For example, the service information for the printer server is often unnecessary for the
remote station of the IPX router. If this information is to be excluded from the SAP table
by means of the LAN filter table, the following entry is required:
Start-service
030c
For a list and description of SAP services, please refer to the section entitled 'Novell SAP
Numbers'.
WAN-filter- As with the LAN filter table, you can use the WAN filter table to prevent ranges of service
table
information from being transferred from the WAN to the SAP table.
Therefore, the blocked services have resulted in the establishment of a connection to the
remote station before the destination router could filter them on the WAN side.
The layout and function of the WAN filter table are exactly the same as that of the LAN
filter table. A WAN filter table for filtering file services might, for example, have the
following appearance:
Start-service
0004
Server/FRM This parameter sets the maximum number of services that can be included in a SAP
frame. The specified value originally defined by Novell is 7. Today, however, it is
common practice to pack a higher number of services in each frame in order to reduce
network utilization. If all participating devices in the network support a higher number,
this value can be raised as high as 22.
Aging-minute(s) This option allows you to set the number of times the SAP table will be updated until an
entry in the SAP table ages, i.e. until the service recorded there is marked as "not
reachable (down)". You can enter a value from 1 to 60; the default value is 3.
