802.3x/backpressure, Tx Capability and Addr. Learning

Select “configure port” in (Port Configuration) and choose corresponded ports, and then

click(Update) .

(port status) and(port configuration) :

(port status) means the true status of port link negotiation.

Through combination key shift+p can configure PoE Mode at ports, as below, options set

to enable to the electrical port, disable as normal port. PD (Powered device) port means

link up with POE power supply. Normal port means linkup with PoE power supply.

By default, port 1 as normal port from the beginning to end (no configuration) , other ports

are PD ports. Only port1 can supply power to hanging down PD (Output 10W power) .

3.2 Port Mirror

System provides port mirror, that is, copy the packets in specific or more ports to

monitoring port for packet analysis and monitor. As following picture, select monitor port in

(Dest Port) and monitored port in(Source Port) .(Monitored Packets) includes: disable,

Rx, Tx and Rx&Tx. Choose needed configuration and click(Update)

Caution: One-to-one port monitor is not supported.

3.3 Bandwidth Control

In this function, user can configure the max sending and receiving rate. The speed

granularity is: Low 32Kbps and High 512Kbps.

Formula: Max sending and receiving rate

=Rate control (0~255) x 32 kbps (low bandwidth)

=Rate control (0~255) x 512 kbps(high bandwidth)

Click (update) to update configuration. Click (LoadDefault) to restore to default

configuration. After that, the speed rate is connecting speed as following:

Note: If the connecting speed rate is smaller than the bandwidth control rate, the

connecting speed rate will be bandwidth control rate.

3.4 Broadcast Suppression

As following, select port in (Enable Port) and input 0-63 in threshold which means the max

broadcast number permitting in certain in the port. Port rate 10Mbps equals to 5000us

time unit, and port rate 100Mbps equals to 500us time unit time.

3.5 CpuCar and port enable configuration

CpuCar mainly use to set port about the number of packets per unit time on the CUP,

Enable means global open, selected port means enable CpuCar, rate by default 200pps,

range 150-300, Disable means global shutdown.

Enable port is switch, non-selected port will shutdown.

Chapter 4 VLAN Configuration

4.1 VLAN Mode

VLAN modes divide into Port Based VLAN and Tag Base VLAN. By default is Port Based

VLAN mode. As below figure:

Click (Change VLAN mode) to shift VLAN mode. On Tag Base VLAN mode page, user

can configure Tag attribution, including Tag, Unmodify and Untag as following:

Note: If the link partner is a network interface card, it probably cannot recognize the

VLAN tag. In this case, it is strongly recommended the network administrator to remove

the VLAN tag of the corresponding port.

4.2 VLAN Member

It can be divided according to VLAN mode:

1. Port Based VLAN member configuration

(Port) is uplink port configuration and (Dest PORT) is downlink port configuration.

(LoadDefault) is default configuration. For example: configure e0/1 to be uplink port and

e0/1~16 to be downlink port to make e0/1 transmit packet to e0/2~16 as following:

Click (LoadDefault) to restore to default value, that is, all (Port) contains all (Dest PORT) .

Note: Configured downlink port must contain uplink port, such as (Dest PORT) must

contain e0/1.

2. Tag Base VLAN member configuration

Divide 16 groups of VLAN (1-16) in Tag Base VLAN mode, which cannot delete and

create. We suggest user click (Read) to load corresponded VID of configured VLAN and

enter VID (1-4094). Select VLAN member in (Dest PORT) and enter pvid corresponded

VLAN Index No. in (PVID Index) and click (Update) .

When deleting VLAN, click (Delete) of the delete VLAN VID in the drop down menu.

When modifying VLAN, modify the VLAN ID in the drop down menu in front of (Delete) ,

When VLAN Member Port ticks or non-ticks VLAN member port, VID Source port ticks

or non-ticks VLAN selected port, click(Update) .

4.3 VLAN Fast Configuration

Port isolation settings are based on Port Based. (Choice port number) is for uplink port.

For example, uplink port chooses 01, port disable as 02, click (update) configure. Port 1

doesn’t transmit packets to port 2 after configuring, but can transmit to all downlink ports.

VLAN member as below:

Chapter 5 Packet Accounting

5.1 Packet Accounting

Packet accounting includes four types: Receive Packet & Transmit Packet, Transmit

Packet & Collision Count, Receive Packet & Drop packet, and Receive Packet & CRC

error packet, after choosing types, click (update) set account type. Click (refresh)

refreshed value. Click (set to Zero) to zero.

Note: System doesn’t refresh automotive, click (refresh) by manual.

Chapter 6 QoS Configuration

6.1 Priority Mode

Priority mode includes:

1. FIFO (First-in first-out)

When queue scheduling, switch will handle packet with time order (the default mode) .

2. PQ (Strict-Priority Queue

When queue scheduling, PQ precedently transmits the packets in superior priority

according to the priority level. Transmit packet in inferior priority when the superior one is

empty. Put the key service in the superior one, and non-key service (such as email) in

inferior one to guarantee the packets in superior group can be first transmitted and

non-key service can be transmitted in the spare time.

3. WRR (Weighted Round Robin)

WRR queue scheduler divides a port into 4 outputting queues that is Q1, Q2, Q3, Q4 and

each scheduler is in turn to guarantee the service time for each queue. WRR can

configure a weighted value (that is, Q1, Q2, Q3, Q4 in turn) which means the percentage

of obtaining the resources. For example: There is a port of 100M. Configure its WRR

queue scheduler value to be 50, 30, 10, 10 (corresponding Q1, Q2, Q3, Q4 in turn) to

guarantee the inferior priority queue to gain at least 10Mbit/s bandwidth, to avoid the

shortage of PQ queue scheduler in which packets may not gain the service.

Note: When the queue weight is set to "0", it will be treated as "8".

6.2 Priority Configuration Based on TCP/UDP and IP TOS/DS

1. QOS based on TCP/UDP

Configure FTP here, the famous port number SHH etc, UserDEF_a, UserDEF_b,

UserDEF_c are self-defined port number, range as 1-65535, not overlap. Inspect

TCP/UDP priority with the ticked ports; no configure about QSW at TCP/UDP protocol

ports.

Note: it is effective for selected ports in Q1~Q4, dorp is for all ports, no valid with

famous numbers in self-defined ports.

2. IP/DS priority

(TOS priority) includes seven types of IP/DS:6'b001010, 6'b010010, 6'b011010,

6'b100010, 6'b101110, 6'b110000 and 6'b111000, tick off selected ports, click (update) .

6.3 802.1p and Physical Port Priority

1. 802.1p priority configuration

As below figure, tick off relevant ports, click (update).

2. Physical port priority configuration

As below figure, each port chooses Q1~Q4, click (update) .

Note: four types of priority: TCP/UDP, IP TOS/DS, 802.1p and Physical port

TCP/UDP>IP TOS/DS>802.1p>Physical port, TCP/UDP priority is higher than other 3

types.

Chapter 7 Packet Security Filtering

7.1 MAC Address Binding

As below figure, (Binding) makes enable, or invalid, (Read) means reading port bounded

MAC. Each port can bind 3 groups of MAC address. Packet whose MAC has not bound will

not be transmitted.

For example, configure (Select Port) e0/1, select enable in (Filter) and bind MAC address

00:0a:5a:01:01:01. After successful configuration, e0/1 will only transmit packet whose

source address is 00:0a:5a:01:01:01.

Note: By default, (Filter) of each port is disabled.

7.2 TCP/UDP Filtration

When (Function Enable) is enable, it means this function is efficient.

Deny in(Port Filtering Rule) means port packet of selected protocol is dropped and packet

of other protocol can be transmitted. Allow means port packet of selected protocol is

transmitted and packet of other protocol can be dropped.

(Secure Port) means configuring WAN interface of TCP/UDP filtration.

(Protocol) includes 20 different network protocols. In addition, UserDEF_a, UserDEF_b and

UserDEF_c are user defined port protocol (these three protocols need configuring on QoS

page of TCP/UDP).

Such as to enable this function, configure port filtration to deny, select secure WAN port01,

and then select Protocol FTP. After successful configuration, port01 will drop FTP packet.

Chapter 8 Spanning Tree

is most often sourced from, and destined for, other networks.

Bandwidth

The difference between the highest and lowest frequencies

available for network signals. The term also is used to

describe the rated throughput capacity of a given network

medium or protocol. The frequency range necessary to

convey a signal measured in units of hertz (Hz).

broadcast storm

An undesirable network event in which many broadcasts are

sent simultaneously across all network segments. A

broadcast storm uses substantial network bandwidth and,

typically, causes network time-outs.

10BASE-T

10BaseT, which is part of the IEEE 802.3 specification, has a

distance limit of approximately 328 feet (100 meters) per

segment. See also Ether Channel and IEEE802.3.

100BASE-TX

standard.

Auto-negotiation

Auto-negotiation (formerly NWay) is an Ethernet procedure

by which two connected devices choose common

transmission parameters, such as speed and duplex mode. In

this process, the connected devices first share their

capabilities as for these parameters and then choose the

fastest transmission mode they both support.

QoS Quality of Service
