IP1810  8-Port 10/100M + 2-Port 10/100/1000Mb Ethernet Switch

General Description :


IP1810 is a non-blocking, store-and-forward architecture switch controller, which builds 8-port 10/100Mbps Fast Ethernet MAC and PHY, 1-port GMAC with RGMII interface and 1-port with RGMII/MII for external CPU in a single chip. 

IP1810 embeds a 4Mb SRAM for the use of packet buffer. It also provides various 2-wire interfaces, such as CPU interface, SMI, and EEPROM interface, which allow the user to access the internal register, external PHYs registers and EEPROM data. The serial LED can show the status of each port (such as Link, Speed, Activity and so on) by using 74HC164 or IP403 external device through 2-wire (LEDCLK, LEDDAT) signals driving from IP1810.  

There are 16K entries in Lookup table. Hashing method can be selected either direct or CRC hashing for MAC address learning. Lookup Table aging time can be adjustable ranging from 55 seconds to 500 hours. IP1810 also provides the MAC learning threshold to limit the number of addresses learning.

IP1810 has 4k entries for 802.1Q VLAN, which provides more security for VLAN member, and supports Independent VLAN Learning (IVL) and Share VLAN Learning (SVL). Further, IP1810 also has add/remove C-tag, S-tag, VLAN remarking, uplink link port and inactive VID redirect functions for the flexible VLAN application. 

IP1810 has 128 entries for ACL table. The ACL (Address Control List) function provides advanced and flexible control mechanism to decide what packet should do (action) if packet matches ACL rule. 

IP1810 supports the web based management interface, such as Microsoft Internet Explorer or Mozilla Firefox, Google chrome, user can more easily configure IP1810s functions by these browsers, and no extra program is needed. Besides, IP1810 also provides IRMP(IC+ remote management protocol) to let the users remotely configure the registers of IP1810.

The IP1818 can partition the network traffic by programming the VLAN table. Furthermore the IP1818 supports both non-VID related tag based VLAN and VID related tag based VLAN. The access control based on the MAC layer, the IP layer and TCP/UDP layer provides a method for the user to implement the Class of Service and the network security.  

 An MCU based web controller to work with IP1818 can easily support the web management. Users can remotely configure and monitor IP1818 smart switches through browsers, such as Microsoft Internet Explorer or Chrome and no program installation is required for the smart switch management.
