Half Duplex Backpressure Flow:

This is used to have nodes verify there is buffer space before packets are sent.

Broadcast Storm Filtering Control:

This is used to set a threshold for the number of broadcast packets to be received from 1 port before port forwarding is blocked.

Section 2

GigaFast

QoS Configuration

QoS Configuration is used to configure the QoS control registers. Press the

‘Refresh’ button to read the status of the registers. Press the ‘Update’ button to set the registers.

The EE2400-SS can recognize QoS priority information from the incoming packets to send the packet to different priority queue for different service priority. The EE2400-SS identifies the packet’s priority based on 3 type of QoS priority information: 1) Port based priority; 2)802.1p/Q VLAN tag; 3) The TCP/IP TOS/DiffServ (DS) priority field. These 3 types of QoS can be configured by hardware pins, EEPROM or Registers 0x0400, 0x0401.

2-6

EE2400-SS support 2 level priority queues. The queue service rate is based on the packet based Weighted Round Robin algorithm. The packet based service weight ratio of high-priority and low-priority queuing can be set as 4:1, 8:1, 16:1 or "Always high priority first”.

Section 2

GigaFast

Port based priority

802.1p based priority

When 802.1p tag priority is applied, the EE2400-SS can recognize the

802.1Q VLAN tag frames and extract the 3-bit User_Priority information

from the VLAN tag. The RTL8326 set the threshold of User_Priority as 3.

Therefore, VLAN tagged frames with User_Priority value = 4~7 will be

treated as high priority frames, and treat other User_Priority values (0~3)

as low priority frames (following 802.1p standard).

Differentiated Service based priority

When TCP/IP's TOS/DiffServ (DS) based priority is applied, the EE2400-

SS can recognize TCP/IP Differentiated Services Codepoint (DSCP)

priority information from the DS-field defined on RFC2474. The DS field

byte for IPv4 is the Type-of-Service (TOS) octet, and for IPv6, it is the

Traffic-Class octet. The recommended DiffServ Codepoints is defined in

RFC2597 to classify the traffic into different service classes. The EE2400-

SS can extract the Codepoint value of the DS-field from Ipv4 and IPv6

packets, and identify the priority of the incoming IP packet following the

definitions listed bellow:

High priority: whose DS-field =

(EF,expected forwarding:) 101110; (AF, Assured Forwarding:) 001010; 010010; 011010; 100010 (Network Control:) 11x000.

Flow control auto turn off scheme

The EE2400-SS can automatically turn off 802.3x flow control and Back

pressure flow control for 1~2 seconds whenever the port receives a high

priority frames. The flow control is re-enabled when no priority frames are

received for 1~2 seconds. This auto-turn off function is enabled by

hardware pin EnFCAutoOff or Register 0x0400.

VLAN Configuration

Setting VLAN Control Registers. Press the Refresh button to read the VLAN control registers. Press the Update button to set the registers, and it will set all VLAN control registers to the selection.

EE2400-SS support VLAN function to broken the switch up into 32 VLAN, each VLAN is a broadcast domain .Each VLAN member can be flexible configured from 0 to 26 port members. Both Port-based and Tag-based VLAN function is supported. The VLAN Table, PVID , Tagging Control and Ingress/Egress Rules are configured on the VLAN Table by manual at registers 0x030B~0x037C . The VLAN table format is shown as follows: Where “VID” define the 802.1Q VLAN ID. The values of VID are not allowed to be: 0x000 and 0xfff. And “Port Member Set” defines the VLAN group member via 26 bit map.

Section 2

VLAN Table Format:

VLAN Entry Index

VID (12bit)

Port Member Set (26 bit) (bit map)

GigaFast

The per-port default PVID is defined at PVID register (0x030C~0x0318) which is a VLAN Table entry index to map to a 12 bit VID. Every port should be assigned to a unique PVID. The VID of each VLAN Table entry should be different. The Overlapped port groups are allowed, this feature make is easily to allow a server port to be shared between different VLAN groups without the routing through an external router device.

The VLAN is used to broken the broadcast domain to limit the broadcast scope. The VLAN Frame Forwarding Rules is defined as follows:

- A received broadcast/multicast frame will only be flood forward to all the VLAN

member ports (“Port Member Set” in the table) of the classified VLAN except the source port.

- A received unicast frame will be forward to the destination port only its destination

port is in the same VLAN as the source port.

- If the destination port belongs to a different VLAN, the frame will be discarded.

But it is allowed to forward if the leaky VLAN control is enabled.

*Note* All VLAN group share with the same L2 MAC table (Shared Learning) to learn the MAC address.

Support Port-based VLAN

By setting the register 0x030B to disable the En8021Qaware control bit, the Portbased VLAN function is enabled and the 802.1Q VLAN tagging is ignored. All other VLAN Table configurations are not different to Tag-based VLAN function. The VLAN classification of any incoming packet on a port for Port-based VLAN is defined by the port PVID. EE2400-SS use the PVID to search VLAN table to get the VLAN member.

2-11

Support 802.1Q Tag-based VLAN

By setting the register 0x030B to enable the En8021Qaware control bit, the 802.1Q Tag-based VLAN function is enabled. And then EE2400-SS will act as an 802.1Q VLAN aware. The VLAN classification is the first step to be done before VLAN table lookup. To classify a unique VID value to a received frame is defined as follows:

Section 2

GigaFast

<1> for a VLAN-tagged frame:

* If the tagged 12-bits VID!= 0 , then the tagged VID value is used. * If the tagged VID = 0 (Null VID, priority tag), then the port's PVID value is used.

<2> for a non-VLAN-tagged frame:

The port's 12-bits PVID value is used. After the unique 12-bits VID is classified, RTL8326 then lookup the VLAN table, check the ingress/egress rule and then forward to the valid destination ports with specified tagging control process.

Ingress/Egress Filtering Control Parameters

Two VLAN filtering rule control parameter are provided on register 0x030B:

- Acceptable frame type control: to admit all frames or to admit only VLAN-tagged frames.

- Ingress Filtering control: to enable filter the frame received from a port which port is not included in the classified VLAN group member.

Support leaky VLAN feature

EE2400-SS support the leaky VLAN feature to enable the ability for some specific frame to be forward between different VLAN. For example, the VLAN table entry is

VLAN 1 = port # 1, 2, 3. VLAN 2 = port # 4, 5, 6.

Normally, any broadcast/multicast and unicast packet all not allowed being switch between these two VLANs. port #1 broadcast packet will only flood to port #2,3 , and port #1 unicast packet is not allowed to forward to any member of VLAN 2. If the leaky VLAN function is enabled, 3 types of specific frame could be forward to different VLAN destination port:

- Unicast packet leaky control : to enable the packet to be forward to a destination port (L2 table lookup hit) at different VLAN.

- ARP broadcast leaky control: to enable ARP frame to broadcast to all switch ports.

- IP multicast leaky control : to enable IP multicast packets to be flood to all the multicast address group member set ignore the VLAN member set domain limitation.

These 3 type of leaky control is useful for a switch to be broken into many VLAN and want to enable host to host communication between different VLAN without any router or with router but improve the router performance.

Insert/Remove VLAN priority tag

EE2400-SS Support the Output Priority tagging control via set register 0x0319~0x031C. User can set 3 types of VLAN tagging control:

- Remove the VLAN tag from all tagged frame.

- Insert priority tag into the untagged high-priority frame. (Set priority field = 7, VID field = 0 for high priority frame.)

- Insert priority tag into the all untagged frame. (Set priority field = 7, VID field = 0 for high priority frame; Set priority field = 0, VID field = 0 for low priority frame.)

- don’t touch. (Not modify the packet)

Note: The function could be enabled even the VLAN function is not enabled.

Device Features

Setting IGMP Snooping Control register and IP Multicast Router Port Discovery register. Router port report will show the IP multicast Router port list. Press the Refresh button to read the register. Press the ‘Update’ button to set the registers, and it will set the register to the selection.

EE2400-SS Support the ASIC based IGMP snooping function which can be enable via register 0x0308 and no other external CPU handling is required. It support the ability to parser the IGMP control protocol packets and IP multicast data packets to learn the multicast router port and group address member ports into the multicast address table. EE2400-SS differentiates between IGMP control protocol packets according to the message type: Router protocol packets (IGMP query packets and multicast routing protocol packets) and group member protocol packets (IGMP v1, v2 Report and Leave packets). The multicast table is build up based on the IGMP report and leave packets. The Multicast Router port is build up based on the router protocol packets. An IP multicast data packet (Dest. MAC = 0x01005exxxxxx) received will involves multicast group table lookup and forwarding operations. If the table lookup returns a hit, the data packet is forwarded to all the member ports. If the multicast address is not stored in the address table (i.e. lookup miss), the packet is broadcasted to all ports of the broadcast domain. The Multicast table is combined with L2 MAC table. So the max entry is 8k entries. For a given multicast entry, the valid port member bit will auto aging out after about 5 min if the port never received the corresponding group address IGMP report packet during 5 min.

Management security scheme

Two RRCP security scheme of EE2400-SS are implemented: (1) RRCP management authorized port control (2) Protocol Authentication Key control. (1) RRCP management authorized port control: The authorized port can be configured via register 0x0201~0x0202. Only the authorized port received RRCP frame commands will be process and response. Other RRCP with DA=switch’s MAC address will be drop. Protocol Authentication Key control: Every RRCP control frame need with a correct Authentication Key that defined in the register 0x0209. After power on, the Authentication Key is reset as the default value (0x2379). It can be update through a valid RRCP Set command or through Serial CPU interface.
