Storing Source Routing Information
The SAP (Service Access Point) route-guess table stores source
routing information. It is updated using the routing information kept in
one of the following:
Auto—Send as the most appropriate frame type, based on the
entries in the SAP route-guess table. (See “SAP Route-
Guess Table,” later in this section, for more information.)
This setting is useful for most environments. However,
under certain circumstances (such as an extremely heavy
network load, network source routing policies, or an
obscure mixture of servers using different source routing
types at the same SAP) you may need to switch to one of
the other settings.
Off—Send without source routing information.
This setting is useful in strictly “transparent bridge”
environments or with old equipment that doesn’t support
source routing. Received frames with route information are
still answered along that specific route, but when the
source routing table entry times out, the route cannot be
rediscovered from the CrownNet interface.
Single—Send as a spanning-tree-explorer frame, also known
as a single-route-broadcast frame.
This setting is useful in environments where there are no
“transparent bridges” and where a spanning tree protocol is
successfully used by the Token-Ring bridges.
Default Auto
Effectivity Changes to this menu take effect as soon as the printer is put
back on line.
Notes The source routing table maintains 16 entries. After 20
seconds these entries default to the setting in this menu.
This cannot be configured from CrownAdmin 3 unless you use
remote console.
