3Com 155 PCI manual Enter the Elan name

Configuring LECs and Resilient Server Links 4-15

6Enter the ELAN name.

In most cases, the ELAN name should match a preconfigured name on the ATM switch, such as the 3Com CELLplex™ 7000 switch. Other manufacturers may have different requirements. Refer to your ATM switch documentation for details concerning ELAN naming.

7Enter the link type.

Select Ethernet or Token Ring according to your need.

8Enter the card numbers of the designated active NICs if the current card is to be a standby NIC.

An entry in the Home Parameter field makes the current NIC (the NIC associated with the current card number) a standby NIC. Enter the card numbers (separated by commas) of the active NICs to be assigned to this standby NIC. When the Home Card parameter is set, any previously configured LECs with the same card number as the standby NIC are ignored.

The Link LED of a standby NIC does not light until it assumes the configuration profile of a failed active NIC.

9Enter the maximum frame size.

■Enter 1514 when communicating with Ethernet LAN segments.

■Enter 4542 when communicating with 4 Mbps token ring LAN segments.

■Enter 9232 when communicating with 16 Mbps token ring LAN segments.

An end station can only communicate with end stations that are using the same maximum frame size, also known as the maximum transfer unit (MTU). Make sure that the ATM switch supports the specified maximum frame size.
