IXE541616

The Intel^® Media Switch IXE5416 16-Port Gigabit Device is a single-chip 16-port solution for layer 2 and layer 3 Gigabit Ethernet switching. The device uses a shared-memory architecture to achieve gigabit wire speed switching on all ports.

The highly integrated chip includes MACs, Address look-up CAM, Switch Engine, Primary Buffer Memory and programmable Quality of Service. The only external components required are the physical layer devices (Phys), and a management CPU. A secondary buffer memory can be used with the chip. The MACs interface to the physical layer through an IEEE compliant GMII/MII for 10/100/1000 Mbit/s operation or the TBI for 1000 Mbit/s operation.

The IXE5416 supports layer 2 switching and layer 3 routing at wire-speed, along with support for VLANs, link aggregation, traffic prioritization and packet filtering based on layer 2 and layer 3/4 information.

The internal CAM holds all tables used in forwarding and VLAN tagging. Up to 8K entries are supported internally. For applications requiring larger address tables, there is an external interface for the Intel^® Media Switch IXE5417 CAM (Content Addressable Memory). This memory provides storage for an additional 96K of layer 2 and layer 3 addresses.
