Figure 3-3 Configuring Protection Parameters

2. In the Protect Type drop-down list box, there are three protection types: No Protection, HSB, SD, and FD. Configure the protection type according to actual requirement. l No Protection indicates that the system has no protection, only Link ID should be configured, and other parameters need not be configured. l HSB indicates that the system adopts the protection of 1+1 hardware hot backup. l SD indicates that the system adopts the protection of antenna diversity reception. l FD indicates that the system adopts the protection of different transmitting and receiving frequencies. 3. If Protect Type is not No Protection, the Protect Mode drop-down list box contains Revertive, Automatic, and Forced. Select the protect mode according to actual requirement. l If Revertive is selected, it indicates that when service signal on the active path is degraded, the service is switched to the standby path; when service signal on the active path becomes normal, the service is switched back to the active path. In this case, the Revertive Time parameter should be configured. This parameter defines the time of waiting for the service to switch back to the active path, and the value range is 300 ~ 800 s. l If Automatic is selected, it indicates that the system will perform automatic switchover according to the active/standby path status. In this case, all the other parameters except for Link ID are disabled, and the system automatically sets the IF/RF transmitting path and the revertive time. l If Forced is selected and if the protection type is HSB+SD, then IFTxPath and RFTxPath should also be specified. If FD is selected, then only IFTxPath should be specified. 4. The value range of Link ID is 0 ~ 255. It is recommended to configure different IDs for microwave links at the same link and microwave links of different directions that converge at the microwave station. 5. Click Apply to complete the configuration. 3-4 SSJ-20110704155716-005|2011–07–30 (R1.0)



Note: When the protection parameters of microwave link are modified, the service will be interrupted instantaneously.


3.4 Configuring ATPC Parameters Context The ATPC function means adjusting the transmitting power at the local end according to the receiving power at the remote end. If the receiving level at the remote end is not within the ATPC adjustment range, it is necessary to adjust the transmitting power to make the receiving power at the remote end be within the adjustment range. If the transmitting power of ODU is adjusted to the threshold value but the receiving power at the remote end is not within the ATPC adjustment range, there is no need to adjust the transmitting power.

Steps 1. Choose Configure > Radio Link in the left navigation tree, and the radio link configuration interface is displayed, as shown in Figure 3-4. User can configure the ATPC parameters here. Figure 3-4 Configuring ATPC Parameters

2. In the ATPC Enable drop-down list box, select ON or OFF to enable or disable the ATPC function. l If OFF is selected, the system cannot perform automatic power adjustment. l If ON is selected, the system can perform automatic power adjustment. 3. If ATPC Enable is set to ON, ATPC High Threshold and ATPC Low Threshold should also be configured. Usually, the two parameters use the default value. Max Tx Power and Min Tx Power can be configured. The values must be within the range of ODU transmitting power. 4. Click Apply to complete the configuration.

3-5 SSJ-20110704155716-005|2011–07–30 (R1.0)



Note: During the process of exchanging microwave link's antennas, ATPC Enable should be set as OFF, and the transmitting power of ODU must be set with the maximum value. After the antennas are exchanged, set ATPC Enable to ON.


3.5 Configuring ACM Function Context The ACM function means that the equipment can adopt different modulation modes according to the current channel status.

Steps 1. Choose Configure > Radio Link in the left navigation tree, and the radio link configuration interface is displayed, as shown in Figure 3-5. User can configure the ACM function here. Figure 3-5 Configuring ACM Function

2. In the ACM Enable drop-down list box, select ON or OFF to enable or disable the ACM function. l If ON is selected, it indicates that the ACM function is enabled, and the system automatically adjusts the modulation mode according to the radio link status to ensure a reliable radio link communication. l If OFF is selected, it indicates that the ACM function is disabled, and the system does not automatically adjust the modulation mode according to the radio link status. 3-6 SSJ-20110704155716-005|2011–07–30 (R1.0)



3. In the Start Profile drop-down list box, select the starting modulation mode. Usually, the lowest modulation mode QPSK is selected. 4. In the End Profile drop-down list box, select the ending modulation mode. Usually, the highest modulation mode 256QAM is selected. 5. Running Tx Profile and Running Rx Profile define the modulation modes of the running system. 6. Click Apply to complete the configuration.

Note: During the process of exchanging antennas of the microwave link, ACM Enable should be set as OFF. The ACM function is implemented only after it is enabled at both ends of the link. Enabling and disabling ACM Enable will cause instantaneous service interruption.

5.1 Related Configurations NR8250 supports the following Ethernet service functions: l l l l l l l

Ethernet service global configuration, which involves working mode (transparent transmission and Virtual LAN (VLAN)), age time, and VLAN ID. Ethernet port configuration, which involves port enabling and duplex/half-duplex. Ethernet port description. VLAN/TRUNK configuration, which involves Trunk ID, VLAN ID, and PVID. Flow control/port rate configuration. QoS configuration. STP/RSTP configuration.

5.1.1 General Configuration Steps 1. 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 based on the actual service requirement. 3. Type the time value for Age Time. This is the aging time of MAC address list. The value range is 15 ~ 3825 seconds, and the default 300 seconds is often used. 5-1 SSJ-20110704155716-005|2011–07–30 (R1.0)

5.1.2 Configuring VLAN Context VLAN is short for Virtual Local Area Network. Pay attention to the difference between VLAN and VPN (short for Virtual Private Network). VLAN means that devices of a local network are logically divided into several network segments to implement data switching between virtual work groups. In other words, the devices are not divided physically, work stations in the same VLAN are not restricted to be in the same physical range, and they can be located in different physical network segments of the local network. This new technology is applied in switches and routers, and the mainstream application of it is in switches. Only switches 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) randomly selected. In this way, work groups in the network are divided according to the management functions, and are not restricted by the geographical locations. The work-flow-based group mode greatly improves network planning and network reorganization. l For work stations in the same VLAN, no matter which switch they are actually connected, the communication among them seems as if it is implemented through an independent switch. Broadcast within a VLAN can only be heard by the members of 5-2 SSJ-20110704155716-005|2011–07–30 (R1.0)

the VLAN, and will not be transmitted to other VLANs. It helps control the broadcast storm. Meanwhile, if there is no route between two VLANs, the communication between them will fail. It helps enhance the security between different departments in the enterprise network.

Steps 1. In the left navigation tree, choose Configure > ETH Traffic > General. set Chip Working Mode to VLAN. 2. In the left navigation tree, choose Configure > ETH Traffic > VLAN. The VLAN configuration interface is displayed, as shown in Figure 5-3. Figure 5-3 Default VLAN Configuration

3. In the VLAN configuration interface, click to configure parameters including the port type and PVID of VLAN, as shown in Figure 5-4, Figure 5-5, and Figure 5-6. Figure 5-4 Access Port

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 frame entering the Access port must be a frame having no label, labeled with PVID of the port, or VLANID as 0. The frame going out of the Access port must be a frame not having label. Set Port Type to Trunk: The port can be configured with multiple VLANs. The frame entering the Trunk port must be a labeled frame and the label is in the VLAN of the port. 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, having a VLAN label as 0. The Egress Policy of the Hybrid port has two types: UnModify and UnTag PVID. UnModify means not making modification, and the frame can be labeled or not labeled. UnTag PVID differs from UnModify in that when VLAN ID of the 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 are removed. Remove: Delete VLANs within the specified range. Remove All: Delete all VLANs. 5-5 SSJ-20110704155716-005|2011–07–30 (R1.0)



Note: If more than 2000 VLANs are configured, the time for configuring port type or adding or 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, link binding, or link convergence. It converges multiple ports, which encapsulate the same link-layer protocol, to form a convergence group and implements outgoing/incoming load sharing at the ports of all members. Link convergence provides higher connection reliability. When a link is disconnected, the flow will be reallocated automatically among the remaining links. The trunk function is implemented dynamically or statically. The dynamic solution is implemented through the IEEE802.3ad LACP protocol. The static solution is implemented through manually configuring Trunk by the manager. To make the link convergence port implement the trunk function: l

l

Physical parameters at the two ends of the convergence port must be consistent. Such parameters include duplex mode, port learning status, port type (electrical/optical port), and port rate. Logical parameters at the two sides of the convergence port must be consistent. Such parameters include VLAN, QoS, and RSTP of the port.

Steps 1. In the left navigation tree, choose Configure > ETH Traffic > General. set Chip Working Mode to VLAN. 2. In the left navigation tree, choose Configure > ETH Traffic > Trunk. The Trunk Configuration interface is displayed, as shown in Figure 5-8.

5.1.5 Configuring FC and Rate Context Flow Control (FC) is used to prevent data packet loss when the port is blocked. It is implemented by sending the blocked signal to the source address when the sending buffer or receiving buffer overflows. FC effectively prevents the impact on the network due to the transient large amount of data and ensures a highly efficient and stable running of the network service. FC is implemented through the following two methods: l

l

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

Steps 1. 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)

3. Based on the service requirement, select Enable or Disable in the drop-down list of FC for each port. The default setting is Disable. l Disable indicates that the Ethernet service port does not perform flow control. l Enable indicates that the Ethernet service port performs flow control. 4. In the Default Priority drop-down list of each port, select a value in the range 0 ~ 7. The value 0 indicates the lowest priority, and 7 indicates the highest priority. Configure this parameter based on the actual requirement. 5. Select Enable or Disable in the drop-down list of BC (flooding) Prevention for each port. The default setting is Disable. Configure this parameter based on the actual requirement. 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 rate exceeds the specified rate threshold, the package will be prevented, namely, will not 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. – End of Steps –

5.1.6 Configure QoS Context QoS is short for Quality of Service. For the network service, the service quality involves the transmission bandwidth, transmission delay, and packet loss rate.
