- Single-Chip 5+1-Port 10/100/1000 Switch Controller
- The RTL8366SB and RTL8366RB are 164/216-pin, low-power, high-performance 5+1-port Gigabit Ethernet switches, with integrated 5-port Giga-PHY that supports 1000Base-T, 100Base-T, and 10Base-T, and with one extra GMII/MII/RGMII port for specific applications. They integrate all the functions of a high-speed switch system; including SRAM for packet buffering, non-blocking switch fabric, and internal register management into a single CMOS device. Only a 25MHz crystal is required; an optional EEPROM is offered for internal register configuration.
- The embedded packet storage SRAM in the RTL8366SB/RB features superior memory management technology to efficiently utilize memory space. The RTL8366SB/RB integrates a 4K-entry look-up table with a 12-bit 4-way XOR Hashing algorithm for address searching and learning. The table provides read/write access from the EEPROM Serial Management Interface (SMI), and each of the entries can be configured as a static entry. The entry aging time is between 200 and 400 seconds. Eight Filtering Databases are used to provide Independent VLAN Learning and Shared VLAN Learning (IVL/SVL) functions.
- The 5th port MAC or PHY of the RTL8366SB and RTL8366RB implement dual MII/RGMII interfaces (the 6th port MAC of the RTL8366RB provides a single GMII interface) for connecting with an external PHY or MAC in specific applications. This interface could be connected to an external CPU or RISC as 5-port Gigabit Router applications. In router applications, the RTL8366SB/RB supports Port VID (PVID) for each port to insert a PVID in the VLAN tag on egress. When using this function, VID information carried in the VLAN tag will be changed to PVID.
- Note: The RTL8366RB (only) Extra Interface (5th port MAC or PHY, and 6th port MAC) supports:
- • Media Independent Interface (MII)
- • Gigabit Media Independent Interface (GMII) (1000Mbps only)
- • Reduced Gigabit Media Independent Interface (RGMII)
- • Port 4 supports 1000Base-X SerDes or UTP
- The RTL8366SB/RB supports standard 802.3x flow control frames for full duplex and optional backpressure for half duplex. It determines when to invoke the flow control mechanism by checking the availability of system resources, including the packet buffers and transmitting queues. The RTL8366SB/RB supports broadcast/multicast output dropping, and will forward broadcast/multicast packets to non-blocked ports only. For IP multicast applications, the RTL8366SB/RB supports IPv4 IGMPv1/v2/v3 and IPv6 MLDv1/v2 snooping.
- In order to support flexible traffic classification, the RTL8366SB/RB supports 32-entry ACL rule check and multiple actions options. Each port can optionally enable or disable the ACL rule check function. The ACL rule key can be based on packet physical port, Layer2, Layer3, and Layer4 information. When an ACL rule matches, the action taken is configurable to Drop/Permit/Redirect/Mirror, change priority value in 802.1q/Q tag, and rate policing. The rate policing mechanism supports from 64Kbps to 1Gbps (in 64Kbps steps)
- In Bridge operation the RTL8366SB/RB supports 8 sets (based on Filtering Database) of port configurations: disable, block, learning, and forwarding for Spanning Tree Protocol and Multiple Spanning Tree Protocol. To meet security and management application requirements, the RTL8366SB/RB supports IEEE 802.1x Port-based/MAC-based Access Control. For those ports that do not pass IEEE 802.1x authentication, the RTL8366SB/RB provides a Port-based/MAC-based Guest VLAN function for them to access limited network resources. A 1-set Port Mirroring function is configured to mirror traffic (RX, TX, or both) appearing on one of the switch’s port. Support is provided on each port for multiple RFC MIB Counters, for easy debug and diagnostics.
- To improve real-time or multimedia networking applications, the RTL8366SB/RB supports eight priority assignments for each received packet. These are based on (1) Port-based priority; (2) 802.1p/Q VLAN tag priority; (3) DSCP field in IPv4/IPv6 header; and (4) ACL-assigned priority. Each output port supports a weighted ratio of four priority queues to fit bandwidth requirements in different applications. The input bandwidth control function helps limit per-port traffic utilization. There are 2 leaky buckets for each queue of all ports, one for Average packet rate control and the other for Peak packet rate control. Queue scheduling algorithm can use Strict Priority (SP) or Weighted Fair Queue (WFQ) or mixed.
- The RTL8366SB/RB provides a 4K-entry VLAN table for 802.1Q port-based, tag-based, and protocol-based VLAN operation to separate logical connectivity from physical connectivity. The RTL8366SB/RB supports four Protocol-based VLAN configurations that can optionally select EtherType, LLC, and RFC1042 as the search key. Each port may be set to any topology via EEPROM upon reset, or EEPROM SMI Slave after reset. The RTL8366SB/RB also provides options to meet special VLAN application requirements. The first option is the ARP VLAN function, which is used to select to broadcast ARP frames to all VLANs, or only forward ARP frames to the originating VLAN. The second option is the Leaky VLAN function, which sends unicast frames to other VLANs, or only forwards unicast frames to the originating VLAN. The VLAN tags can be inserted or removed on a per-port basis.
- In router applications, the router may want to know the input port of the incoming packet. The RTL8366SB/RB supports an option to insert a VLAN tag with VID=Port VID (PVID) on each egress port. The RTL8366SB/RB also provides an option to admit VLAN tagged packet with a specific PVID only. If this function is enabled, the RTL8366SB/RB will drop all non-tagged packets and packets with an incorrect PVID.
