3Com 3C971-F manual Configuring Network Channels

Configuring Network Channels 4-7

is always configured. When used to emulate multiple adapters, channels 2 through 4 are also configured.

For LAN emulation services, each channel becomes a LAN emulation client (LEC) and can be set to contact the LAN emulation configuration server (LECS), or set to contact a LAN emulation server (LES) directly. In a typical LAN emulation network, the LECS provides the client with a central point of contact for obtaining the MTU (Maximum Transfer Unit) size, ELAN name, and ATM address for the LES the client is to join. In NetWare networks, the MTU size is fixed at 1514 bytes and cannot be changed by the user.

CAUTION: You must configure Channel 1, the default channel, before exiting the Protocols/Parameters dialog box in Figure 4-8. The configuration procedure is the same whether single or multiple channels are used. At the end of the configuration procedure, you choose whether to exit the setup or to continue configuring additional channels.

To configure the channels for the 3C971-F adapter, the driver files must be copied to the server as described in the previous section, and you must be at the Protocols/Parameters dialog box shown in Figure 4-8. Follow these steps:

1Select Select/Modify driver parameters and protocols at the bottom of the dialog box.

The highlight bar moves to the TCP/IP option in the Protocols box.

2To change the protocol from the default (IPX) protocol, select the desired protocol.

If TCP/IP is selected, the dialog box in Figure 4-9 appears. Edit the TCP/IP information as follows:
