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
