NET/SWI/101 - Gigabit Ethernet Switch

8-port Ethernet switch (Xbar, SNMP, IEEE 1588 V1/V2 Grandmaster)

The NET/SWI/101 is a Gigabit Ethernet switch designed for operating in harsh environments. Each port on the NET/SWI/101 is full-duplex only and can be set for 10BASE-T, 100BASE-TX, 1000BASE-T link speeds or auto-negotiate.

The NET/SWI/101 has a store-and-forward Xbar switching fabric that uses the Trivial File Transfer Protocol (TFTP) to specify multiple user-defined static forwarding tables and filtering configurations. Specific configurations are user selectable via the Simple Network Management Protocol (SNMPv2c). The Xbar static forwarding table defines how incoming Ethernet frames received on a given port are forwarded to the output of one or more egress ports.

The output of each port has filtering capabilities allowing for selective forwarding of Ethernet frames to the connected end node. The filter comprises a lookup table of up to eight 16-bit fields, including wildcards.

The NET/SWI/101 has an embedded IEEE 1588v1 and 1588v2 PTP Grandmaster. The Grandmaster can use a GPS input, a digital IRIG-B input, an analog IRIG-B input, or the internal free-running clock to provide the time source. Bridging between 1588v1 and 1588v2 domains is supported using a boundary clock.
