ATM Forum LAN Emulation Ethernet and TCP/IP (DOS, OS/2) Not
Working
Default parameters of DOS TCP/IP and 8265 Ethernet LEC do not match; a DOS TCP/IP station cannot
ping an 8265.
The 8265 TCP/IP LEC is Ethernet 802.3 by default (with version v1.0.0). The IBM TCP/IP drivers for DOS
and OS/2 are configured for DIX (Ethernet v2) by default. As a result, the TCP/IP IBM stations configured
with the default parameters will not be able to ping the 8265
Perform either of the following:
1. Change the TCP/IP frame type to 802.3 on the TCP/IP stations, using the CUSTOM.EXE ('Advanced
Configuration') for DOS TCP/IP, or the TCPIPCFG.EXE for OS/2 TCP/IP 2.0.
2. Keep the TCP/IP frame type of DIX and change the 8265 LEC Ethernet type to DIX, using the
command SET DEVICE LAN_EMULATION_CLIENT ETH_TYPE DIX.
DOS TCP/IP Installation TIPS
To install the TW25 adapter for TCP/IP:
1. Install the TW25 drivers for 802.3 from the TW25 disks.
2. Install TCP/IP with the NODIS interface.
3. Append the NDIS.DDI file with the TW25 information. For example,
copy c:/tcpdos/etc/ndis.ddi +
a:/eth/at25led.ddi c:/tcpdos/etc/ndis.ddi
4. Run CUSTOM.EXE. The ATM adapter will now appear in the drop-down box.
5. Do not allow the CUSTOM.EXE to overwrite the PROTMAN or AT25LED lines.
6. The CUSTOM.EXE will now complete. The PROTOCOL.INI in the AT25LEI directory will be the one
TCPDOS appends with its stanza.
