3Com 155 PCI manual Diagnostic Utility Description, Only one LEC per NIC is supported in NetWare

Software Descriptions 1-5

The NetWare 4.x and 3.12 drivers and Windows NT network drivers support up to four physical NICs per system.

Each physical NIC can be configured to support up to 16 LECs. Each LEC operates as a virtual NIC and has a unique MAC address.

Only one LEC per NIC is supported in NetWare 3.12.

The ATMLink NIC network driver uses switched virtual circuits (SVCs) to establish network connections with up to 4,096 open virtual channel connections (VCCs) supported per system. Each LEC requires a minimum of four VCCs in addition to those needed for its data requirements. These four VCCs are used by the LAN Emulation Server (LES) and the Broadcast and Unknown Server (BUS).

Resilient server links allow the network administrator to designate up to three of the installed 3C975 ATMLink NICs as standby NICs. In the event of link failure, the standby NIC assumes the configuration profile and network traffic of a failed active ATMLink NIC. Resilient server links are discussed in Chapter 3 and Chapter 4.

The ATMLink network drivers let the ATM network administrator set a maximum peak cell rate value for each LEC. This form of bandwidth allocation is useful in mitigating congestion and ensuring optimum usage of bandwidth.

Diagnostic Utility Description

The ATMLink diagnostic utility is a DOS program that tests the internal integrity of the 3C975 ATMLink NIC and its ability to send and receive packets. The diagnostic utility also identifies the MAC address, the PCI slot number, and manufacturer’s information for each installed 3Com ATMLink NIC. It is recommended that you run the diagnostic utility after installing the ATMLink NIC and before installing the network drivers. For information on how to use the diagnostic utility, see Chapter 6, “Diagnostics and Troubleshooting.”
