NetWare Glossary
T
Custom configuration. You can list the specific time servers that a particular
server should contact.
You can also specify that a server shouldn’t listen for SAP information from
other time sources, and that it is not to advertise its presence using SAP
An advantage of custom configuration is that the network supervisor maintains
complete control of the time synchronization environment.
Also, custom configuration helps eliminate nonessential network SAP traffic, as
well as errors associated with accidental reconfiguration.
A disadvantage of custom configuration is the increased time required for
planning and installation.
Also, it is more difficult to install or remove Primary, Reference, or Single
Reference time servers. You must manually change the approved server list
maintained on each server.
Which time synchronization method to use
On small networks where it is unlikely that servers will be added or
reconfigured after initial installation, we recommend that you use a Single
Reference time server using SAP (the installation default).
On larger networks, or on networks subject to frequent accidental
reconfiguration when servers are added or removed, custom configuration is
recommended.

Topology
The physical layout of network components (cables, stations, gateways,
hubs, etc.). There are three basic topologies:
• Star network. Workstations are connected directly to a NetWare server but not to
each other.
• Ring network. The NetWare server and workstations are cabled in a ring; a
workstation’s messages may have to pass through several other workstations
before reaching the NetWare server.
• Bus network. All workstations and the NetWare server are connected to a central
cable (called a trunk or bus).
