LAN driver configuration

Use this procedure to configure the protocol stack for use with NetWare Services.

The following list describes the prerequesites:

• Access to scoadmin(1M)

• System Owner permission to use scoadmin's NetWare Setup utility

1. To change your driver configurations, from scoadmin, select NetWare, then select the NetWare Setup utility.

2. Select IPX/SPX.

3. Select LANs.

4. Double-click on the LAN you want (for example, ``lan_1'').

   The ``lan_number'' window appears.

5. Set the following variables as appropriate:

   • Basic. The Basic category shows the most commonly changed UnixWare LAN variables:

     • IPX LAN Network Address. This variable specifies the IPX external network number for cabling. All IPX drivers linked to this cable must use the same network number.

     • IPX LAN Device Name. This is the name of your LAN device, for example /dev/NE2000. Click to view the list of devices.

     • IPX LAN Device Type. This variable specifies the LAN topology type for the IPX interface. Select the type of LAN cabling topology you have. Click to view the list of types.

     • IPX LAN Frame Type. Type the logical frame type you want; for example, ETHERNET_II or ETHERNET_802.2. Click to view the list of frame types.

     • LAN Speed in Kilobytes/Second. This variable specifies the speed in kilobytes (KB) per second that the data is transferred across the network. This value is used to calculate the number of ticks (1/18 second) for router packets. This speed depends upon your network type; for example, an Ethernet II network is 10000KB/sec.

   • Advanced. The Advanced category shows and allows you to change the less commonly used LAN variables.

     • Interval Between RIP Broadcasts. This variable specifies the number of 30-second intervals between RIP broadcasts. The default is 2 (or 60 seconds).

     • RIP Ageout Interval. This variable specifies the number of RIP broadcast intervals to elapse since the last broadcast packet was received before a network is considered down and removed from the Router Information Table. The default is 4 minutes.

     • Delay in Milliseconds between RIP Packets. This variable specifies the number of milliseconds the RIP driver waits between sending packets on the LAN. This option prevents receiving servers or routers from receiving packets too fast. This variable is ignored if ``Minimize WAN RIP Traffic'' is set to ``Yes''. The default is 55.

     • Maximum RIP Packet Size. This variable specifies the maximum size, in bytes, for RIP packets. The size may be smaller if you specify a size larger than the network supports. The default is 432.

     • Minimize WAN RIP Traffic? This variable allows an administrator to minimize RIP traffic on the WAN and indicates whether the RIP driver broadcasts only to indicate changes in router availability or broadcasts information periodically. ``Yes'' means RIP broadcasts changes only. ``No'' means RIP periodically broadcasts server information. The default is ``No''.

     • SAP Ageout Intervals. This variable specifies the number of SAP broadcast intervals to elapse since the last broadcast packet was received before a server is considered down and removed from the Server Information Table. The default is 4 minutes.

     • Interval between SAP Broadcasts. This variable specifies the number of 30-second intervals between SAP broadcasts. The default is 2 (or 60 seconds).

     • Delay in Milliseconds between SAP Packets. This variable specifies the number of milliseconds the SAP daemon waits between sending packets on the LAN. This option prevents receiving servers or routers from receiving packets too fast. The default is 55.

     • Maximum SAP Packet Size. This is the maximum size, in bytes, for SAP packets. The size may be smaller if you specify a size larger than the network supports. The default is 480.

     • Reply to Get Nearest Server Requests? This variable specifies whether responses are sent to Get Nearest Server requests. NetWare clients send out Get Nearest Server requests when they first establish a connection. ``Yes'' means that SAP will respond with the address of the nearest server. ``No'' means SAP will not respond with the address of the nearest server. The default is ``Yes''.

     • Minimize WAN SAP Traffic? This variable allows an administrator to minimize RIP traffic on the WAN and indicates whether the SAP driver broadcasts only to indicate changes in router availability or broadcasts information periodically. ``Yes'' means SAP broadcasts changes only. ``No'' means SAP periodically broadcasts server information. The default is ``No''.
