How to add port description on Huawei OLT MA5680T/MA5683T/MA5608T

This topic describes how to add port description.

PrerequisitesA board must be added to the system.

Context

After the description of a physical port on the board is added, the description facilitates information query in system maintenance.

Procedure

In the global config mode, run the port desc command to add port description.

Run the display port desc command to query port description.

Port description is a character string, used to identify a port on a board in a slot of a subrack.

Example

Plan the format of user port description as "community ID-building ID-floor ID/subrack ID-slot ID-port ID". "Community ID-building ID-floor ID" indicates the physical location where the user terminal is deployed, and subrack ID-slot ID-port ID" indicates the physical port on the local device that is connected to the user terminal. This plan can present the user terminal location and the connection between the user terminal and the device, which facilitates query in maintenance. Assume that the user terminal that is connected to port 0/2/0 of the MA5600T/MA5603T/MA5608T is deployed in floor 1, building 01 of community A. To add port description according to the plan, do as follows:

What’s the Triple Protection of Huawei MA5600T/MA5603T/MA5608T

The Huawei MA5600T/MA5603T/MA5608T provides 3 protection mechanisms on the access side, network side, and device side to ensure that services are not interrupted.

Huawei OLT Network Side

On the network side, the OLT supports ring technologies, such as link aggregation, Multiple Spanning Tree Protocol (MSTP), and Ethernet ring protection switching (ERPS), to ensure uninterrupted service running. Figure 1 shows the OLT network-side protection.

MSTP blocks redundant paths so that the loop network can be trimmed as a tree network to avoid proliferation and endless cycling of packets on the loop network. MSTP also enables redundant links to share load based on the VLAN.

ERPS ensures quick service restoration (service interruption time: ≤ 50 ms) during the interruption of an upstream physical link.

Huawei OLT

On the access side, the OLT supports GPON type x protection, as shown in Figure 2.

The OLT supports type B protection, providing 1+1 protection for GPON ports and backbone optical cables and ensuring the switching time less than 50 ms.

The OLT supports type C protection, providing 2 PON ports to connect to the ONU and providing 1+1 protection for backbone optical cables, optical splitters, and distribution optical cables. For type C single-homing, the switching time is less than 50 ms. For type C dual-homing, the switching time is less than 120 ms.

How to Deploying Network Devices (GPON Upstream)

This topic describes how to deploy network devices in the scenario with or without the NMS.

Prerequisites

Network devices and lines must be in the normal state.

The control board and the GPON service board of the OLT must be in the normal state.

Context

When the ONU adopts the GPON upstream transmission, the SN is used for authentication.

Scenario with the NMS

The procedure for deploying network devices in the scenario with the NMS is as follows: 

1, According to the user's FTTx data plan, the commissioning engineer prepares the network planning sheet and obtains the resource deployment sheet.

2, The commissioning engineer imports the resource deployment sheet through the NMS to implement the predeployment for the ONU.

3, The hardware installation engineer draws the ONUs and sends them to the destination sites, and then performs hardware installation, wiring, and power-on operations at the destination sites.

4, The hardware installation engineer checks the running status of the ONU that is installed and powered on.

There are two LEDs, namely Link and Auth, on the ONU.

If the Link LED is on, it indicates that the upstream optical path is through.

If the Auth LED is blinking, it indicates that the ONU is registering.

If the Auth LED is always on, it indicates that the ONU registers successfully.

5, After confirming that the ONU works in the normal state (the Link LED is on and the Auth LED blinks), the hardware installation engineer records the ONU SN and reports the SN to the commissioning engineer.

6, The commissioning engineer maps the ONU SN, the management IP address of the ONU, and the physical position of the ONU, and binds the IP address and the SN of the ONU through the NMS.

7, After being powered on, the ONU registers with the OLT automatically. Then, the OLT sends the management channel parameters of the ONU (management VLAN, IP address, and SNMP parameters) to the ONU and also sends the trap message to the NMS for informing the NMS that an ONU goes online.

8, The commissioning engineer receives the trap indicating that the ONU goes online reported by the OLT on the NMS.

9, After the trap indicating that the ONU goes online is received on the NMS, the ONU management channel is enabled successfully. Then, you can remotely configure services for the ONU through the NMS.

What’s the Access-Aggregation Integration of Huawei MA5680T

The MA5600T/MA5603T can implement FTTH/DSLAM access and FTTB/FTTC/DSLAM Ethernet aggregation in the same subrack to provide a unified traffic aggregation point on the FTTH/FTTC/FTTB/FTTD network, thereby achieving aggregation of different network construction modes, eliminating the need to construct an independent access-aggregation network layer, and simplifying the network architecture.

The Huawei MA5600T supports a maximum non-aggregation forwarding capability of 40 Gbps x 16 GE.

The MA5600T and Huawei MA5603T support the 48-port high-density aggregation board and provide access for a maximum of 768 GE ports.

The OLT supports Layer 3 functions and can be used as an aggregation edge device. It possesses powerful Layer 3 service processing capabilities, such as 40G switching capability and 60 Mpps Layer 3 forwarding capability in the 8 x 10 GE upstream load-sharing mode. With these capabilities, the OLT can:

The Huawei MA5600T and MA5603T support the mature all-service MPLS solution, as shown in the below picture:

Reduce upper-layer service traffic and shorten network transmission delay. Specifically, the OLT can directly perform Layer 3 switching for local traffic, thereby lowering the traffic pressure of the upper-layer network and pressure of network traffic expansion.

Simplify the network architecture. Specifically, Layer 2 aggregation switches do not need to be deployed, thereby streamlining the network layers.

Improve network security. Specifically, the upper network does not learn the user-side MAC addresses, thereby eliminating the risks of MAC spoofing and broadcast storms.

The Huawei MA5600T and MA5603T support service transmission over ATM PWE3, TDM PWE3, ETH PWE3, VPLS, and L2VPN.

The MA5600T and MA5603T feature high service performance. Specifically, they support quick E2E service protection (service switching time: ≤ 200 ms).

The MA5600T and Huawei MA5603T do not have limitations on service authentication and terminal VLAN planning, simplifying network design and maintenance.

How to configure Anti-Attack

Enabling anti-DoS attack and anti-ICMP/IP attack, and configuring the source route filtering and source MAC address filtering functions can prevent malicious users' attack on the system, so as to improve system security.

Background Information

The Huawei MA5600 supports the following measures to prevent malicious users' attack on the system. Choose measures according to actual requirements.

Anti-DoS attack: Indicates the defensive measures taken by the system to receive only a certain number of control packets sent from a user.

Anti-ICMP attack: Indicates the defensive measures taken by the system to drop the ICMP packets sent from the user-side device to the MA5600. This is to prevent the user-side device from pinging the VLAN interface of the Huawei MA5600.

Anti-IP attack: Indicates the defensive measures taken by the system to drop the IP packets sent from the user-side device to the MA5600.

Source route filtering: Indicates the defensive measures taken by the system to filter the IP packets that are sent by the user and carry the routing option field.

Source MAC address filtering: Indicates the defensive measures taken by the system to filter the packets that are sent by the user and carry certain source MAC addresses.

User-side ring network check: Indicates the defensive measures taken by the system to check user-side ring networks. In this manner, the system can process ring networks to prevent ring networks from affecting services.

Procedure

Configure anti-DoS attack.

Configure anti-ICMP attack.

Enable anti-IP attack.

Enable the source route filtering function.

Configure the MAC address filtering function.

Run the security anti-dos enable command to enable anti-DoS attack. After the anti-DoS attack function is enabled, the system adds the user port to the blacklist if the receive rate of the control packet of the user reaches a preset value. When anti-DoS attack is disabled, the system deletes the blacklist.

Application scenario: Two PCs (PC1 and PC2) are connected to the network through the MA5600. If a malicious user (PC1) sends a large number of protocol control packets to attack the CPU of the MA5600, the CPU usage of the MA5600 will be over high, and then the MA5600 is unable to process the services of another user (PC2). To implement anti-DoS attack, shield the attack port to protect the MA5600 from being attacked.

Run the security anti-icmpattack enable command to enable anti-ICMP attack. Anti-ICMP attack is used to prevent the user-side device from pinging the VLAN interface of the Huawei MA5600.

Application scenario: Two PCs (PC1 and PC2) are connected to the network through the MA5600. When PC2 sends a large number of ICMP packets to the VLAN interface, the services of the user (PC1) that obtains the upper-layer DHCP information through the same VLAN interface will be abnormal. To implement anti-ICMP attack, directly drop the user-side ICMP packets if the IP address of the VLAN interface on the MA5600 is its destination IP address.

Run the security anti-ipattack enable command to enable anti-IP attack. The anti-IP attack is used to prevent user-side IP packets from attacking the L3 interface of the device or to prevent illegal users from logging in to the device through telnet.

Application scenario: When a PC sends the packets with the address of VLAN x as the destination IP address to VLANIF x, it may send a large number of packets to attack the device, causing the device to fail to process normal services; when a user knows the address of VLAN x, or the user name and password for logging in to the device, it may log in to the device through telnet to randomly change the configurations of the device. To prevent the two preceding cases, the device needs to implement anti-IP attack. With this feature, the device drops the packets with the address of the device interface as the destination IP address to prevent the user from attacking the device.

Run the security source-route enable command to enable the source route filtering function. This function is used to filter the packets that carry the routing information and are reported to the L3 switch.

Application scenario: In general, routes are dynamic and application does not control route selection. The sender can add the routing information to IP packets through the source route to perform route selection. In this case, packets go along a specific route on the network according to the intention of the sender. To prevent the preceding cases, enable the source route filtering function. Then the MA5600 performs validity check on IP packets and drops the packets that match the source route options.

Run the security mac-filter command to enable the MAC address filtering function.

Application scenario: To prevent users from forging the MAC address of the network-side device, or forging certain renowned MAC addresses, set the MAC address of the network-side as the MAC address to be filtered.

When parameter name is 3, it indicates the mode of the message waiting indicator. The range for parameter value is 0-2.

§  0: high voltage.

§  1: FSK and ringing.

§  2 FSK with no ringing.

§  Default: 1

Solution

Change the system parameter 3 on mdu

change the parameter 3 = 2 so that there is no ringing on receiving the NOTIFY message.

Handling Process

A:  1. The GPON protocol shows that the GPON upstream and downstream frames are transmitted at the fixed frequency of 125 us and the upstream bandwidth is 1.24432 Gbit/s, equaling 19440 bytes/s, Huawei GPON service board. 2. The terminal reports the data to be transmitted through the DBRu field of the upstream frame.  3. The GMAC chip on the CO side translates this field, obtains the requested bandwidth value, and finds out the Huawei ONT and TCONT from which this report comes.  4. The bandwidth is allocated according to the bandwidth usage and the parameters of the DBA profile bound to the corresponding TCONT of the Huawei OLT. The allocated bandwidth in the result uses a start byte and a stop byte. The range of the start byte and the stop byte is 0 to 19440 bytes (bandwidth of the upstream frames).  5. The allocation result is applied in BWMAP of the downstream frame. After receiving the downstream frame, the terminal translates the data in BWMAP, finds out the byte sections corresponding to its own TCONT, and then transmits the data through the next upstream frame according to the allocation result.

HG850a PPPoE connection failed due to VAS profile mismatch on BMS

P2P Access: Configuring FTTH Service Issue Description

Customer find that, when HG850a works under Router mode, PPPoE can not be connected, while under Bridge mode it is OK. Upgrade the HG850a to the latest version, problem still exist. HG850a version: V100R001C07SPC008 Huawei OLT  version: V800R007C00SPC300 BMS version: V200R012C05SPC135

Handling Process

1.Since it is OK under bridge mode, it means the config of BRAS is OK, problem should be on the OLT or Huawei ONT. 2.Set the ONT as Router and Bridge mode separately, and capure the trace on the uplink of OLT. Under bridge mode, PADI packet is captured; but under Router mode, there is no any PADI packet, it means HG850a did not send the PADI packet under Router mode, which casued PPPoE can not establish.  3.Check the config file of OLT and HG850a, no fault is found. For further analysis, check the HG850a WAN status by the OLT internal channel: 59-PERM-TEST-O3(su)%%                      an0   576 root        416 S   dhcpc -i wan0 -I wan0   577 root        416 S   dhcpc -i wan0 -I wan0   757 root        616 S   dhcps There is only one DHCP WAN,  but no PPPoE WAN, but on the WEB interface we can see there are 2 WAN: one is DHCP, the other is PPPoE WAN. 4. It is very strange, we dicided to check the XML file more carefully, and found the two WAN ports were using the same WAN ID, both are "1" : On the BMS, we can see that more clearly: As the second WAN ID the same as the first one, the second WAN port(PPPoE) can not start. As a result, PPPoE can not be established. 5. Change the XML manually, to make the WAN ID different. After that,  PPPoE can be established under Router mode too. 6. But problem can not be closed here, need to know how can the 2 WAN ports get the same WAN ID. Customer did not set it, and  there is no where to set the WAN ID on ONT (HG8546M), OLT (MA5683T)or BMS. 7. Take a review of the customer's service-providing process, find that cusotmer bind one VAS profile to generate the XML file, the VAS profile is from other BMS, did not match the customer's BMS, can not understand  all the HG850a nodes, and the same 2 WAN ID appears.  8. Till now the problem is clear and located, VAS profile mismatch BMS, lead to the same 2 WAN ID, and then lead to the second WAN can not be started, and cause the PPPoE can not be established. So, the final solution is to create one VAS profile on BMS manually, the parameter can be the same as before, and then bind the new VAS profile to the ONT, problem can be solved. PS. You can find the following in the attachment: configrations of OLT and ONT, network scheme, trace of OLT uplink.

Root Cause

Null

Suggestions

Don't use the VAS profile from other BMS, better create the VAS  profile on the BMS manually, to prevent some unknown problems.
