NetBIOS Hops
is the maximum number of hops allowed for routing a Novell-encapsulated NetBIOS
frame. (Each router in a packet's path to the destination network is one hop.) Frames
exceeding this value will be discarded.
Periodic RIP Enabled
determines whether the node will originate periodic IPX Routing Information Pro-
tocol (RIP) messages from this interface (assuming RIP is enabled), to inform the
network that the route through this interface is viable.
Periodic RIP Timer
is the interval between the periodic IPX RIP broadcasts from this interface.
Periodic SAP Enabled
determines whether the node will originate periodic IPX Service Advertising Protocol
(SAP) messages from this interface (assuming SAP is enabled), to inform the network
which SAP entries in the routing table are viable.
Periodic SAP Timer
is the interval between the periodic IPX SAP broadcasts from this interface.
RIP Enabled
determines whether this interface will support RIP processing.
RIP Age Timer
is used to delete route entries in the routing information table (assuming RIP is
enabled). The timer starts/restarts each time an entry is created/updated by RIP or ref-
erenced for forwarding. If the timer expires, the router will assume that the entry is no
longer valid (due to hardware failure, power outage, etc.), and the entry will be deleted
from the table.
RIP Maximum Size
is the maximum possible RIP packet size, including the IPX header (30 bytes) and the
LAN MAC header (if transmitted on a LAN interface).
SAP Enab led
determines whether this interface will support SAP processing.
SAP Age Timer
is used to delete route entries in the server information table (assuming SAP is
enabled). The timer starts/restarts each time an entry is created/updated by SAP or ref-
erenced for forwarding. If the timer expires, the router will assume that the entry is no
longer valid (due to hardware failure, power outage, etc.), and the entry will be deleted
from the table. SAP will then send a broadcast message indicating that the server is
down.
Transport Time
is the time (in 55-millisecond units) that it will normally take to forward frames out
the interface. Recommended values are
1
for LAN interfaces and
30
for WAN inter-
faces.
This time is used to calculate the least-cost path during routing. If
IPXWAN Enabled
(described later) is
Y
,
Transport Time
will be overridden by the value calculated by
IPXWAN.
