N2000BMS shows the alarms with an early hour because the NE does not have configured the right time zone

Issue Description

The alarms displayed in the N2000BMS are displayed with an early hour.
The alarm is reported in the OLT MA5600V800R007
Example:
the next alarm is reported in Huawei MA5600T at 01:39:49-05:00, but, in the N2000BMS appear the same alarm at 02:39:49. The time in the N2000BMS is the real time.

Handling Process

Because of the BMS had the correct time, so, it was supposed that the DST was not configured in the NEs.
It was analyzed the time settings and the time zone  in Huawei OLT.

Ceylan(config)#display time                                                  
{ <cr>|dst<K>|time-stamp<K> }:                                                 

  Command:                                                                   
          display time                                                       
  2011-11-02 10:10:03-05:00                                                                                                                                 
Ceylan(config)#display timezone                                              
The current time zone:  GMT-05:00
it was found that the timezone is not the correct. So it was requested change the timezone to make a test.

After modify the time zone to the correct one, the alarms was reported in the N2000BMS with the correct time.
However, to avoid changing the timezone every period of time, it was suggested to enable the DST.

Ceylan(config)#display time dst                                              
  Failure: DST has not been configured  
  

Suggestions

Verify the timezone of the country to set the correct one in the NE or in the Server. Also, consider use the DST feature.

QoS Planning Principles

QoS plan for FTTB is in E2E mode, and it can be divided into following policies: traffic
classification, marking, scheduling, traffic monitoring, and DBA policies.

Traffic Monitoring and DBA Policies

T-CONT (used only in GPON networks):Use different T-CONTs for different services.
DBA type: Select a DBA type based on service types. For example, select Type1 for
the management and voice services, and Type3 or Type4 for the Internet access and IPTV services.
DBA bandwidth planning: Configure the DBA bandwidth according to the user's bandwidth
package. The assured bandwidth is the maximum bandwidth required by management packets, VoIP, and IPTV upstream packets. The maximum bandwidth is greater than or equal to the maximum bandwidth that users apply.
Rate limit on ONU uplink port: Set ONU port rate limit or Huawei xDSL line rate limit as required.
Rate limit on ONU downlink port: Set ONU port rate limit or xDSL line rate limit as required.

VoIP service: The upstream bandwidth and the downstream bandwidth of VoIP service are
symmetrical. The actual bandwidth varies with the coding format. This bandwidth is calculated for two POTS ports.

IPTV service (common program): IPTV service mainly occupies the downstream bandwidth. The actual bandwidth depends on the coding format, the picture in picture information, 10% bandwidth burst traffic, and the number of programs that can be concurrently watched by one user (in the case of multi STBs access). The upstream bandwidth is mainly used for transmitting IGMP packets, which
requires little bandwidth and can be neglected.

Rate limit on the BRAS or SR is recommended. Huawei OLT and ONU do not limit rates on
service flows. If the BRAS does not support rate limit, OLTs can limit rates on service
flows using traffic profiles.

l The sum of assured bandwidth of all ONTs under a PON port and the fixed bandwidth of
OMCI management channel must be smaller than Huawei GPON upstream bandwidth. Some
bandwidth must be reserved for future service expansion.

Configuring FTTH Service (P2P Access)

Users connected to the OLT through an ONT, and are therefore provided with the Internet,
VoIP, and IPTV service through a same port.

Service Requirements

• ONT_1 and ONT_2 are provided with the triple play service through Huawei FTTH.
• The Internet access service is provided in the PPPoE access mode.
• The IPTV user connected to ONT_1 can watch all the programs, and the IPTV user connected to ONT_2 can watch only program BTV-1.
• The VoIP service and the IPTV service are provided in the DHCP mode and obtain IP, addresses from the DHCP server in the DHCP option-60 mode.
• After receiving different traffic streams, the OLT provides different QoS guarantees to the traffic streams according to the priorities of the traffic streams.
• Traffic streams are differentiated on the OLT by the user-side VLAN (C-VLAN).

Example network of the optical fiber access service in the single-port for multiple

services mode

Prerequisite

• Huawei OLT is connected to the upper-layer devices such as the BRAS, multicast server, SoftX3000, and DHCP server.
• The VLAN of the LAN switch port connected to the OLT is the same as the upstream VLAN of the OLT.

Configure the Internet access service on the OLT.

a. Create a VLAN and add an upstream port to the VLAN.

The VLAN ID is 100, and the VLAN is a smart VLAN. The upstream port is 0/9/0.

b. Configure a traffic profile.

Because the VoIP, IPTV, and Internet access services are provided through the same

port, you must set the 802.1p priority of each service. Generally, the priorities are in a descending order for the VoIP service, IPTV service, and Internet access service.

In this example, set the traffic profile index to 7 and the priority of the Internet access service to 1.

c. Configure a service port.

Add a service port to the VLAN and use traffic profile 7. The user-side VLAN ID is 2.

d. Configure queue scheduling.

Use the 3PQ+5WRR queue scheduling. Queues 0-4 adopt the WRR mode, with the

weights of 10, 10, 20, 20, and 40 respectively; queues 5-7 adopt the PQ mode.

Configure the mapping between queues and 802.1p priorities. Priorities 0-7 map

queues 0-7 respectively.

e. Save the data.

Configure the VoIP service on Huawei MA5600T.

a. Create a VLAN and add an upstream port to the VLAN.

Data Plan Principles for IP Addresses

Data Plan Principles for IP Addresses

Terminal Type:

1, Bridging+Voice ONT
Internet access:A PC obtains an IP address through PPPoE dialup. The ONT transparently transmits the packets.
VoIP:The ONT functions as a DHCP client and obtains an IP address from the DHCP server, or the NMS issues a static IP address to Huawei ONT using the configuration file. Voice signaling and media streams at multiple POTS ports share one IP address. Media streams are distinguished by port.
IPTV:The set top box (STB) obtains an IP address from the DHCP server for ordering programs. The ONT transparently transmits the packets.

2, Bridging ONT+HGW
Internet access:The HGW functions as a PPPoE client and obtains an IP address through PPPoE dialup. At the same time, the HGW functions as a DHCP server and allocates IP addresses to
PCs through the network cable and wireless fidelity (Wi-Fi) access. The ONT transparently transmits the packets.
VoIP:The HGW functions as a DHCP client and obtains an IP address from the DHCP server, or the application control server (ACS) issues a static IP address to the HGW using
TR069. Voice signaling and media streams at multiple Huawei POTS ports share one IP address. Media streams are distinguished by port. The ONT transparently transmits the packets.
IPTV:The HGW is configured with a bridging WAN port. The STB obtains an IP address from the DHCP server. The,HGW transparently transmits packets. The ONT also transparently transmits the packets.

3, Gateway ONT
Internet access:The HGW functions as a PPPoE client and obtains an IP address through PPPoE dialup. The ONT functions as a DHCP server and allocates IP addresses to PCs through the
network cable.
Wi-Fi access:l Layer 3 bridge Wi-Fi access service: A mobile equipment (ME) searches the SSID. After the ME is authenticated, the DHCP server assigns this ME the IP
address by IPoE. l Layer 3 route Wi-Fi access service: An ME searches the SSID. After the ME is authenticated, the DHCP address pool of an ONT assigns this ME the IP address and then
PPPoE dialup is automatically performed on the ONT such as Huawei HG8546M.
VoIP:The ONT functions as a DHCP client and obtains an IP address from the DHCP server, or the NMS issues a static IP address to the ONT using the configuration file. Voice signaling and media streams at multiple POTS ports share one IP address. Media streams are distinguished by port.
IPTV:The ONT functions as a DHCP client and obtains an IP from the DHCP server. At the same time, the ONT functions as a DHCP server and allocates IP addresses to STBs.

Ethernet trail alarms are not synchronized with real alarms on NEs

Issue Description

Customer M complains that Ethernet trails status is "not alarmed" but when he checks the relevant NE he found that there are some alarms. So the Ethernet trail alarm status is not automatically updated with NE alarms.

Alarm Information

Null

Handling Process

to solve this problem follow the following steps:

.          Stop the nmleth process manually.

.          Modify bRelocateAlarmByTrailAssociate from 0 to 1 in U2000server\nml\nmleth\conf\cfg\nmleth.cfg

.          Restart the nmleth process.

.          Browse current alarms about the faulty trail again.

Alarms are relocated and relationship between the trail and its alarms will be updated. As a result, alarm status is synchronized.

Root Cause

after checking and analyzing we found that the root cause of this problem is located in nmleth.cfg file that is stored in the folder server\nml\nmleth\conf\cfg , in fact there is one parameter that is responsible for displaying trail alarm:  bRelocateAlarmByTrailAssociate , this parameter has the value "0", that is why there was no mechanism to automatically synchronize the trail alarm.

Why can not log in BMS system after V200R011C01B037 BMS newly added the northbound interface components?

Issue Description

When manage Huawei MA5600T, can not log in BMS system after V200R011C01B037 BMS newly added the northbound interface components, why?

BMS version: iManager N2000 BMS V200R011C01B037
Because we didn't choose the northbound interface components at the first installation, the northbound process can't be started and the function can't be usefully. But the northbound function is necessary to the customer, so we have to newly add the northbound interface components. After installed the components, we can't log in the BMS system and the error is "The license file has been overdue".

Alarm Information

Try to log in the BMS system, the error is "The license file has been overdue".

Handling Process

The process is as follows:
1. The BMS is only installed for three days and the probationary period is 90 days;
2. Before the installation of northbound interface components, the system can be logged in successfully. The installation aroused the problem;
3. The installation of new BMS components will update the old license in the system. The error  indicated the new BMS license isn't working, so we think the update has some problems;
4. We checked the updated license file and find it's much bigger than normal license file;
5. Copy other normal license to overlay the error license;
6. Re-start the BMS system, we can log in successfully.

Root Cause

The installation of new BMS components will update the old license in the system. The error information indicated the new BMS license isn't working, so we think the update has some problems.
The BMS version iManager N2000 BMS V200R011C01B037 has the problem. If the problem appeared, we have to copy other normal license to overlay the error license to solve the problem.
