Netfinity® Gigabit Ethernet Adapter User’s guide
• Jumbo Frames
— When checked, Jumbo Frames (up to 9,000 bytes) is supported by the
adapter. This setting can reduce host CPU overhead and increase
bandwidth when sending to other devices that support Jumbo Frames.
When attached to an Alteon WebSystems switch, Jumbo Frames will be
sent only between end-stations that have Netfinity Gigabit Ethernet
Adapters. When sending to standard Ethernet devices, the switch
automatically fragments the Jumbo Frames traffic into standard Ethernet
frames.
— When unchecked (default), only standard-sized Ethernet frames will be
sent. Use this setting when connecting to Gigabit Ethernet equipment that
does not support Jumbo Frames.
• Port Link Speed
When link negotiation is disabled, this parameter sets the port link speed. You
can select link speed to be either 10Mbps, 100Mbps, or 1Gbps. When the port
link is connected, the selected link speed is indicated to the right of this field.
• VLAN Count
This field reflects the number of VLANs configured for the selected adapter.
When there are no VLANs configured for the selected adapter, VLAN support is
disabled. This is an information field and cannot be configured directly through
this tab.
Note: Netfinity Gigabit Ethernet Adapters that are members of a Failover Team
can be configured to support VLANs. However, VLANs cannot be
configured for a stand-alone Intel LAN on motherboard (LOM) or a
Failover Team that includes a LOM.
• Number of NICs in a Team
When a Failover Team is selected in the Adapter list, this field represents the
total number of adapters configured for the selected team. This field does not
apply when an individual (non-teamed) adapter is selected in the Adapter list.
This is an information field and cannot be configured directly through this tab.
12. Perform any optional configuration, if desired.
• To configure Failover Teaming, refer to “Failover Teaming” on page 1-14.
• To configure VLANs, refer to “Configuring VLANs” on page 1-20.
You can perform optional configurations at any time.
13. When configuration is complete, click Close in the Device Driver Properties window.
14. Click Close in the Network window.
Note: If other adapters in your system use TCP/IP bindings, the TCP/IP Properties
window opens.
15. Perform any necessary TCP/IP configuration; then click OK.
For help with configuring TCP/IP protocol, consult your Microsoft Windows NT 4.0
documentation.
