5.1 Related ConfigurationsNR8250 supports the following Ethernet service functions:

l Ethernet service global configuration, which involves working mode (transparenttransmission and Virtual LAN (VLAN)), age time, and VLAN ID.

l Ethernet port configuration, which involves port enabling and duplex/half-duplex.l Ethernet port description.l VLAN/TRUNK configuration, which involves Trunk ID, VLAN ID, and PVID.l Flow control/port rate configuration.l QoS configuration.l STP/RSTP configuration.

5.1.1 General Configuration

Steps1. In the left navigation tree, choose Configure > ETH Traffic > General. The Ethernet

Global Configuration interface is displayed, as shown in Figure 5-1.

Figure 5-1 Ethernet Global Configuration

2. In the Chip Working Mode drop-down list box, select Transparent or VLAN basedon the actual service requirement.

Figure 5-2 Default VLAN Configuration

5. In theWireless Network Capacity drop-down list, select a bandwidth in the range 64K~5 M as required.



5.1.2 Configuring VLAN

Context

VLAN is short for Virtual Local AreaNetwork. Pay attention to the difference between VLANand VPN (short for Virtual Private Network). VLAN means that devices of a local networkare logically divided into several network segments to implement data switching betweenvirtual work groups. In other words, the devices are not divided physically, work stationsin the same VLAN are not restricted to be in the same physical range, and they can belocated in different physical network segments of the local network. This new technologyis applied in switches and routers, and the mainstream application of it is in switches. Onlyswitches of the third layer (or higher) of the VLAN protocol have this function.l In the switching network, the broadcast domain can be a virtual network segment

consisting of a group of layer-2 network addresses (MAC addresses) randomlyselected. In this way, work groups in the network are divided according to themanagement functions, and are not restricted by the geographical locations. Thework-flow-based group mode greatly improves network planning and networkreorganization.

l For work stations in the same VLAN, no matter which switch they are actuallyconnected, the communication among them seems as if it is implemented through anindependent switch. Broadcast within a VLAN can only be heard by the members of

5-2


Chapter 5 ETH Service

the VLAN, and will not be transmitted to other VLANs. It helps control the broadcaststorm. Meanwhile, if there is no route between two VLANs, the communicationbetween them will fail. It helps enhance the security between different departmentsin the enterprise network.

Steps

1. In the left navigation tree, choose Configure > ETH Traffic > General. set ChipWorking Mode to VLAN.

2. In the left navigation tree, choose Configure > ETH Traffic > VLAN. The VLANconfiguration interface is displayed, as shown in Figure 5-3.

Figure 5-4 Access Port

5-3



Figure 5-5 Trunk Port

Figure 5-6 Hybird Port

5-4



Note:

At present, the information of port type, VLAN ID, and PVID are issued separately.

Set Port Type to Access: The port can be configured with only one VLAN. The frameentering the Access port must be a frame having no label, labeled with PVID of theport, or VLANID as 0. The frame going out of the Access port must be a frame nothaving label.

Set Port Type to Trunk: The port can be configured with multiple VLANs. The frameentering the Trunk port must be a labeled frame and the label is in the VLAN of theport. The frame going out of the Trunk port must be a labeled frame.

Set Port Type to Hybrid: The Hybrid port receive frames of the following types:having no VLAN label, having a VLAN label contained in the VLANID of the port, havinga VLAN label as 0. The Egress Policy of the Hybrid port has two types: UnModifyand UnTag PVID. UnModify means not making modification, and the frame can belabeled or not labeled. UnTag PVID differs from UnModify in that when VLAN ID ofthe frame is same as PVID of the port, the label will be removed.

4. There are many ways to add/delete VLAN, as shown in Figure 5-7.

Figure 5-7 Adding/Deleting VLAN

Add: Add VLAN within the specified range.

Add all: Add all the 4094 VLANs.

Add all except: Add VLANs except the specified VLAN. The specified VLANs areremoved.

Remove: Delete VLANs within the specified range.

Remove All: Delete all VLANs.

5-5



Note:

If more than 2000 VLANs are configured, the time for configuring port type or addingor deleting VLAN may be long, generally not more than three minutes.


5.1.3 Configuring Trunk

Context

The trunk function of Ethernet port is also called port binding, port convergence, linkbinding, or link convergence. It converges multiple ports, which encapsulate the samelink-layer protocol, to form a convergence group and implements outgoing/incomingload sharing at the ports of all members. Link convergence provides higher connectionreliability. When a link is disconnected, the flow will be reallocated automatically amongthe remaining links.

The trunk function is implemented dynamically or statically. The dynamic solution isimplemented through the IEEE802.3ad LACP protocol. The static solution is implementedthrough manually configuring Trunk by the manager.

To make the link convergence port implement the trunk function:

l Physical parameters at the two ends of the convergence port must beconsistent. Such parameters include duplex mode, port learning status, port type(electrical/optical port), and port rate.

l Logical parameters at the two sides of the convergence port must be consistent. Suchparameters include VLAN, QoS, and RSTP of the port.

Steps

1. In the left navigation tree, choose Configure > ETH Traffic > General. set ChipWorking Mode to VLAN.

2. In the left navigation tree, choose Configure > ETH Traffic > Trunk. The TrunkConfiguration interface is displayed, as shown in Figure 5-8.

5.1.5 Configuring FC and Rate

ContextFlow Control (FC) is used to prevent data packet loss when the port is blocked. It isimplemented by sending the blocked signal to the source address when the sending bufferor receiving buffer overflows. FC effectively prevents the impact on the network due to thetransient large amount of data and ensures a highly efficient and stable running of thenetwork service.

FC is implemented through the following two methods:

l In the half-duplex mode, FC is implemented by backpressure, namely, backpressurecounter. This counter helps the information source decrease the transmitting rate bysending the jamming signal to the transmitting source.

l In the duplex mode, FC follows the IEEE 802.3X standard, and the switch sends the"pause" frame to the information source to ask it to stop sending data.

Steps1. In the left navigation tree, choose Configure > ETH Traffic > FC & Rate. The Flow

Control and Rate configuration interface is displayed, as shown in Figure 5-11.

Figure 5-11 Configuring FC & Rate (1)

5. Select Enable or Disable in the drop-down list of BC (flooding) Prevention for eachport. The default setting is Disable. Configure this parameter based on the actualrequirement.l Disable indicates that the broadcast package entering the Ethernet port is not

prevented and will be forwarded.l Enable indicates that whether the broadcast package entering the Ethernet port

will be prevented depends on the broadcast package rate. If the package rateexceeds the specified rate threshold, the package will be prevented, namely, willnot be forwarded.

6. If BC (flooding) Prevention is set to Enable, you can configure Ingress RL Value.Type a value within the range 100 ~ 20000 kbps. The default value is 10000 kbps.

7. Click Save, and click Apply to complete the configuration.


5.1.6 Configure QoS

ContextQoS is short for Quality of Service. For the network service, the service quality involvesthe transmission bandwidth, transmission delay, and packet loss rate. The service qualitycan be improved by ensuring the transmission bandwidth and reducing the transmissiondelay, packet loss rate, and delay dithering.
