IP175D 5Port 10/100 Ethernet Integrated Switch
(Policy-base QoS, Layer 2-4 MF Classifier, HW IGMP Snooping)

General Description :

IP175D integrates a 6-port switch controller, SSRAM, and 5 10/100 Ethernet transceivers. Each of the transceivers compliers with the IEEE802.3, IEEE802.3u, and IEEE802.3x specifications. The DSP approach is utilized for designing transceivers with 0.16um technology; they have high noise immunity and robust performance.

IP175D operates in store and forward mode. IP175D have a lot of rich feature for different application, include router application, firewall, IEEE 802.1Q, IGMP snooping, policy-based QoS. It provides powerful QoS function, include traffic policy, traffic meter, and flexible queue scheduling (WRR/WFQ/SP). In virtual LAN, IP175D support port-based VLAN and IEEE 802.1Q tag-tagged VLAN (up to 16 VLAN groups).

IP175D support up to 2K MAC addresses, up to 16 VLANs and up to 8 Multi-Field entries. These tables are accessible through MII register. The address table can configure either “2K unicast addresses” or “1K unicast addresses and 1K multicast addresses“. The Multi-Field classification is powerful classifier (layer2 to layer 4 packet headers) in packet classification. The classifier divides incoming packets into multiple classes based on prescribed rules. Each traffic class from classifier can drop out-of-profile packets, monitor traffic, specify forwarding behavior, and specify output queue.

Beside a 5-port switch application, IP175D supports three MII/RMII ports for router application, one WAN port and one HOME/PNA or Access point. The external MAC can monitor or configure IP175D by accessing MII registers through SMI0.

MII/RMII port also can be configured to be MAC mode. It is used to interface an external PHY to work as 5+1 switch. Through SMI1 IP175D can monitor and configure external PHY
