bytes), frame format, and compliance with the following standards and protocols:

•Logical Link Control (IEEE 802.2)

•Flow Control (IEEE 802.3x)

•SNMP

•Gigabit Ethernet (IEEE P802.3z)

VLANs Support

Virtual Local Area Networks ( VLANs ) are commonly used to split up groups of network users into manageable broadcast domains, to create logical segmentation of workgroups, and to enforce security policies among logical segments.

Each ITI-5100G/GF adapter supports up to 64 VLANs. With multiple VLANs on an adapter, a server with a single adapter can have a logical presence on multiple IP subnets.

Refer to the “Optional Configuration,” section of this manual for configuration information.

Jumbo Frames Support

To reduce host frame processing overhead, the ITI-5100G/GF adapter and Gigabit switches that support jumbo frames, can receive and transmit frames that are larger than the maximum frame size allowed on normal Ethernet.

Dual Homing

Server switching networks require the capability to employ resiliency and redundancy similar to FDDI network environments. ITI-5100G/GF adapters provide the Ethernet user with this capability.

For dual homing support, you must install two ITI-5100G/GFs in the same host system. The adapters are configured to provide a hot-standby failover service. The switches must be configured to support Spanning Tree on both Gigabit Ethernet ports to support the ITI-5100G/GF Dual Homing capability.

Adaptive Interrupt Frequency

The adapter driver intelligently adjusts host interrupt frequency based on traffic conditions, in order to increase overall application throughput. In light traffic, the adapter driver interrupts the host for each received packet, minimizing latency. When traffic is heavy, the adapter issues one host
