IPX Interface Configuration
10-8
Configuring IPX Interfaces
time is used to calculate the least-cost path during routing. If WAN Enabled is set 
to Yes (see above), the Transport Time selected here will be overridden by the 
value calculated by IPXWAN.
NetBIOS Hops
This is the maximum number of network hops allowed for routing a 
Novell-encapsulated NetBIOS frame. Each router in a packetÕs path to the 
destination network is one hop. Frames exceeding this value will be discarded. 
The default value for this parameter is 8.
Periodic SAP Timer
If Periodic SAP Enabled is set to Yes (see above), then this Þeld speciÞes the 
interval (in seconds) between the periodic IPX Service Advertising Protocol (SAP) 
broadcasts from this interface. If this is set to greater than 0, the SAP Age Timer 
(see below) must be three times longer than the Periodic SAP Timer. The default 
value for this parameter is 60.
SAP Age Timer
If SAP Enabled is set to Yes (see above), this timer is used to delete route entries 
in the server information table. The timer starts each time SAP creates or updates 
an entry, or an entry is referenced for forwarding. This Þeld speciÞes the amount 
of time (in seconds) that will elapse before the timer expires and the router 
assumes that the entry is no longer valid (due to hardware failure, power outage, 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. If the value for the Periodic SAP 
Timer is set to greater than 0, the SAP Age Timer must be three times longer than 
the Periodic SAP Timer. A value of 0 for the SAP Age Timer disables aging.
 
The 
default value for this parameter is 180.
Periodic RIP Timer
If Periodic RIP Enabled is set to Yes (see above), then this Þeld speciÞes the 
interval (in seconds) between the periodic IPX Routing Information Protocol (RIP) 
broadcasts from this interface. If this is set to greater than 0, the RIP Age Timer 
(see below) must be three times longer than the Periodic RIP Timer. The default 
value for this parameter is 60.
RIP Age Timer
If RIP Enabled is set to Yes (see above), this timer is used to delete route entries in 
the routing information table. The timer starts each time an entry is created, 
updated, or referenced for forwarding by RIP. This Þeld speciÞes the amount of 
time (in seconds) that will elapse before the timer expires and the router assumes 
that the entry is no longer valid (due to hardware failure, power outage, etc.) and 
the entry will be deleted from the table. If the value for the Periodic RIP Timer is 
set to greater than 0, the RIP Age Timer must be three times longer than the 
Periodic RIP Timer. A value of 0 for the RIP Age Timer disables aging. The default 
value for this parameter is 180.
