[Root Cause]

An error occurs when the JDSU-provided GE optical module is used with the H831CCUC

control board. The LOS decision mechanism of the JDSU-provided GE optical module conflicts

with that of the H831CCUC control board. As a result, the handshake fails, causing a cascading

failure.

[Impact and Risk]

The MA5616 equipped with the H831CCUC control board is delivered with the JDSU-provided GE

optical module (BOM number: 34060286). If the GE optical module is used for cascading, the

cascading fails, affecting deployment.

[Measures and Solutions]

Recovery measures

None

Preventive measure

Configure the MAC chip register in the software.

Solution

Upgrade the control board to V800R310C00SPC103 on new sites in which the cascading is used.

How to Control Board Failure After an MxU Service Port Is Bound to a Rate Unlimited

Abstract: In MxU V800R306C01, V800R307C00, and V800R307C01, the MxU

control board fails after the following operations are performed:

Product Line: Access network product line  Product Model: MA5616

l Create a rate unlimited traffic profile (traffic table ip) through the U2000 or N2000.

l Bind the traffic profile to a service port on the MxU.

Restart the MxU.

[Problem Description]

Trigger conditions:

This issue occurs after all the following requirements are met:

1. A rate unlimited profile is created on the MxU through the U2000 NMS.

2. The MxU version is V800R306C01, V800R307C00, or V800R307C01.

3. The created profile is bound to a service port on the MxU.

Symptoms

After the MxU is restarted, the control board fails. As a result, service boards fail to register

with the control board and the MxU cannot be managed by the NMS.

————————————————————————-

Identification methods

If a control board fails after the MxU is restarted, perform the following operations to determine

that the fault is caused by the issue described in this pre-warning:

1. Verify that the MxU version is V800R306C01, V800R307C00, or V800R307C01.

2. Verify that a rate unlimited profile exists on the MxU and it is bound to a service port on the

MxU.

The following configurations are used as an example:

traffic table ip index 7 name “NOCAR” cir off color-mode color-blind  priority 0 priority-policy

local-setting

……

service-port 0 vlan 1049 eth 0/1/1 multi-service user-vlan untagged  rx-cttr 7 tx-cttr 7

service-port 1 vlan 1050 eth 0/1/2 multi-service user-vlan untagged  rx-cttr 7 tx-cttr 7

3. Query MxU last words. If the following highlighted error codes are displayed for l2qos files,

the fault is caused by the issue described in this prewarning.

HUAWEI(su)%%display lastwords all

……

l2qos_traff  1315          0          0          1 0x7b0       0x7b0

l2qos_traff  1317          0          0          1 0x9c4000   0x9c4000 

l2qos_traff  1424          0          0          1 0x68bafe   0x68bafe 

[Root Cause]

In MxU V800R306C01, V800R307C00, or V800R307C01, if a rate unlimited profile is created

through the NMS, the MxU database may malfunction. The traffic profile cannot restore from the

database after the MxU is restarted. In this case, if the traffic profile is bound to a service port on

the MxU, the service port cannot find the traffic profile in the recovered data. As a result, the MxU

hardware fails to be configured and accordingly, the control board fails.

[Impact and Risk]

The control board fails, services on the MxU fail, and the MxU cannot be managed by the NMS.

[Measures and Solutions]

Recovery measures

Workarounds

1. If an abnormal traffic profile has been loaded to the MxU on the live network but the MxU has

not been restarted, delete the traffic profile from the NMS and use a functional traffic profile.

2. If the MxU has been restarted and the control board fails, create the service port that is bound to

the abnormal traffic profile on the MxU by running commands. Then, save the data.

The procedure is as follows:

Step 1: Run the display saved-configuration command to query the original configuration.

If a service port is bound to the abnormal traffic profile, change the traffic profile to a functional one.

The following configurations are used as an example, where traffic profile 7 is the abnormal profile:

HUAWEI(config)#display saved-configuration

[MA5600V800R305: 12301]

#

[global-config]

<global-config>

traffic table ip index 7 cir 51200 cbs 1024000 pir 102400 pbs 1024000  priority

user-cos 0 priority-policy local-setting

#

[public-config]

<public-config>

snmp-agent local-engineid 800007DB0300E0FC112233

#

[vlan-config]

<vlan-config>

vlan 200

#

[bbs-config]

<bbs-config>

service-port 0 vlan 200 eth 0/1/1 user-vlan untagged  rx-cttr 7 tx-cttr 7

#

return

Step 2: Load the modified configuration file to the MxU or manually change the traffic profile ID to

the one of a functional traffic profile.

The following manual configurations are used as an example:

service-port 0 vlan 200 eth 0/1/1 user-vlan untagged  rx-cttr 6 tx-cttr 6

Step 3: Create the service port with the preceding configurations by running commands.

Step 4: Save the data.

Preventive measures

For the MA562X or MA5616, upgrade the version to V800R308C00SPC508 or later to resolve

this issue.

For MA5620E V800R307 or MA5620G V800R307, the V800R312C00SPC205 is being developed,

which resolves this issue and will be released in the end of 2013.

Solution

For the MA562X or MA5616, upgrade the version to V800R308C00SPC508 or later to resolve

this issue.

For MA5620E V800R307 or MA5620G V800R307, the V800R312C00SPC205 is being developed,

How to Clear the DBMS_ERROR Alarm Reported After an Upgrade

Constraint:

l This recovery guide is applicable to V200R011C03SPC200, V200R012C00, and

V200R012C01 only.

1 Identifying the Problem

1.1 Querying the Database

Run the :dbms-query:”23310000.dbf”,mdb command. The query result is shown

in the following attachment:《Result.txt》

 

1.2 Checking Whether a Residual SNCP Pointer Exists

As shown in the attachment in 1.1 “Querying the Database”, the 3112103 field is 00 but the

23312301 field is not 00000000, so the SNCP pointer exists.

Records 1, 2, 5, and 6 need to be recovered, as shown as follows:

 

SNCP

SNCP

 

2 Recovering the Database

2.1 Identifying the Recovery Mode

2.1.1 V200R011C03SPC200, V200R012C00, or V200R012C01

If the NE version is V200R011C03SPC200, V200R012C00, or V200R012C01, run the :

alm-get-curdata-ext:0,DBMS_ERROR,0; command to check whether the DBMS_ERROR

alarm is reported.

If the DBMS_ERROR alarm is not reported, perform the steps in 2.2 “Recovery Method When No

DBMS_ERROR Alarm Is Reported”; if the DBMS_ERROR alarm is reported, perform the steps in

2.3 “Recovery Method When the DBMS_ERROR Alarm Is Reported”.

2.1.2 Versions Earlier than V200R011C03SPC200 

If the NE version is earlier than V200R011C03SPC200 and a residual SNCP pointer exists, check

whether the DBMS_ERROR alarm will be reported after the upgrade. If the DBMS_ERROR alarm

is not reported, perform the steps in “Recovery Method When No DBMS_ERROR Alarm Is Reported”

after normally upgrading the NE; if the DBMS_ERROR alarm is reported, the activation of the

processing board will time out, so perform the steps in “Recovery Method When the DBMS_ERROR

Alarm Is Reported”.

The method to check whether the DBMS_ERROR alarm will be reported after the upgrade is as follows:

In the query result, the record of the residual SNCP pointer exists. If the value of the 23312301 field is

displayed twice, the DBMS_ERROR alarm will be reported after the upgrade; if not, the DBMS_ERROR

alarms will not be reported.

The query result in 1.1 “Querying the Database” is used as an example. Confirm that records 5 and 6 are

residual data by referring to 1.2 “Checking Whether a Residual SNCP Pointer Exists”. The value of the

23312301 field is c7240000. In the query result, c7240000 is displayed twice. The DBMS_ERROR alarm

will be reported.

 

 

SNCP

2.2 Recovery Method When No DBMS_ERROR Alarm

Is Reported

2.2.1 Running Commands to Recovery the Database

:cfg-gsp-test:”modifyPO 23310000 poid 23312301 00000000″

Poid indicates the decimal value converted from the hexadecimal value of the 14112301 field in

the residual SNCP pointer records. Values of other fields are fixed (pay attention to the space

between data).

For records 1 and 2, the decimal values for 2469 and 246b in the 14112301 field are 9321 and

9323 respectively.

Run the following two commands:

:cfg-gsp-test:”modifyPO 23310000 9321 23312301 00000000″

:cfg-gsp-test:”modifyPO 23310000 9323 23312301 00000000″

Recover all residual records in sequence.

2.2.2 Checking Recovery Results

Run the :dbms-query:”23310000.dbf”,mdb command to confirm that all residual SNCP

pointer records are recovered.

2.2.3 Saving the Database

Run the :dbms-copy-all:drdb,fdb command.

The recovery is complete.

2.3 Recovery Method When the DBMS_ERROR Alarm

Is Reported

2.3.1 Temporarily Allowing External Operations

Run the :sm-set-nebusy:0,0,0,0,none command.

When the DBMS_ERROR alarm is reported, no external operation is allowed on the NE. After

the command is executed, you can perform operations on the NE in five minutes. If the residual

records are not recovered after five minutes, you need to run the command again. Do not

configure the NE during this period.

2.3.2 Running Commands to Recovery the Database

:cfg-gsp-test:”modifyPO 23310000 poid 23312301 00000000″

Poid indicates the decimal value converted from the hexadecimal value of the 14112301 field in

the residual SNCP pointer records. Values of other fields are fixed (pay attention to the space

between data).

For records 1 and 2, the decimal values for 2469 and 246b in the 14112301 field are 9321 and

9323 respectively.

Run the following two commands:

:cfg-gsp-test:”modifyPO 23310000 9321 23312301 00000000″

:cfg-gsp-test:”modifyPO 23310000 9323 23312301 00000000″

Recover all residual records in sequence.

2.3.3 Waiting for Alarm Clearance and Completing Active/Standby

Backup

After completing all recovery operations, wait for about 45 minutes. Run the :

alm-get-curdata-ext:0,DBMS_ERROR,0; command to confirm that the DBMS_ERROR

alarm is cleared. Run the :hbu-get-backup-info command and confirm that the returned

value is 3.

The recovery is complete.

If the returned value is not 3, contact Huawei‘s engineers.

2.4 Upgrade and Recovery Measures for the NE on

Which the DBMS_ERROR Alarm Is Reported After

an Upgrade

The upgrade steps are adjusted. The system control board and processing board are loaded

and activated respectively. Upgrade the system control board. After the fault is rectified,

upgrade the processing board.

2.4.1 Upgrading Active and Standby System Control Boards Based

on Simulation Package Loading

When confirming the simulation loading and activation sequence, for the group where the

system control board is not located, select Pause Before Current Group, as shown as follows:

 

SNCP

SNCP

 

After the system control board upgrade is complete, the NE stops the activation of more boards.

2.4.2 Temporarily Allowing External Operations

Run the :sm-set-nebusy:0,0,0,0,none command.

External operations are not allowed on the NE during backup. After the command is executed,

you can perform operations on the NE in about five minutes. If the residual records are not

recovered after five minutes, you need to run the command again. Do not configure the NE

during this period.

2.4.3 Running the Command to Recovery the Database

:cfg-gsp-test:”modifyPO 23310000 poid 23312301 00000000″

IGMP

R represents the router functions of the IGMP protocol, and H represents the host functions of the IGMP protocol.
In the distributed two-level IGMP protocol stack, the first level is on the control board and the operation on the user side and the network side is based on MVLAN; the second level is on the service board, the operation on the network side is based on MVLAN, and the operation on the user side is based on multicast user, which ensures that users do not affect each other on the control plane. The convergence of the IGMP protocol stack on the service board lightens the processing load of the IGMP protocol stack on the control board. Given the same hardware conditions, the system can process channel switching of more multicast users at the same time.
NOTE:

In the distributed multicast mode, the multicast configuration command and multicast query command are processed through different channels so that they can be executed concurrently. If a configuration command takes a long time to be executed and the corresponding query command is executed subsequently, the result of the query command may not display configuration result, depending on when the query command is executed.

For example, if you run the igmp statistic reset vlan 100 command to clear the IGMP packet statistics and then run the display igmp statistic vlan 100 command to query the IGMP packet statistics of multicast VLAN 100:
When the igmp statistic reset vlan 100 command execution is not completed yet and IGMP packet statistics are not cleared, the query result is not displayed as zero.
When the igmp statistic reset vlan 100 command is executed and IGMP packet statistics are cleared, the query result is displayed as zero.

What’s the Service Interruption on the MA5616?

During a lab test for the SmartAX MA5616 V800R307C02, a service interruption has occurred

due to an exception of the logic. The root cause, however, is not yet identified after more than three

months of efforts to reproduce the issue in the lab. This prewarning notice describes how to identify

this issue and restore the service.

Problem Description

Trigger conditions

Use a SmartAX MA5616 V800R307C02 that is in full configuration of service boards in the test.

Create a service port on each VDSL port, set up a point-to-point over Ethernet (PPPoE) connection

on each service port, and send the packets. Import the configuration file to the device and activate

the file multiple times, and then reset the system. Enable and disable the security function multiple

times and then perform dynamic host configuration protocol (DHCP) dialup and PPPoE dialup multiple

times.

Symptom 1. The dialup on all service ports fails. 2. The uplink and user ports collect statistics of the

received ports but the logic does not collect packet statistics.

Identification method

1 The system cannot forward services and all the services are interrupted. 2 Query the statistics of the

received and transmitted packets on the uplink and user ports to determine whether the packets are

transmitted to the FPGA logic. 2.1 The following screen shows the command and command output for

Tips to buy the home broadband router

Home broadband router is a router that user number is relatively small, such as the 4LAN port router, which can supply 4 computer. To buy a home broadband router, first of all, you should need to know the brand, quality and price, so you can choose a good home broadband router.

1, The router “gateway”, or “agent”?

First to determine the selected router belongs to the “gateway”, or “agent”. The fundamental difference between the two is the gateway does not have the flexible permissions configuration function, and the agent has a flexible configuration, which of course is reflected in the router configuration function. In the home, the family of three, usually in order to limit their children’s online time and unfair network application, the need for children to special computer access privileges for the appropriate restrictions, so the purchase of home routerson the need to pay attention to, to view the purchase of router configuration function if applicable.

 

2 Broadband router access mode

Broadband access mode is very important, especially for the virtual dial-up users of ADSL. Because some routers only support line routing, not the built-in virtual dial-up protocol PPPoE, of course, would not provide virtual dial-up users with dial-up service, the routing function can’t be realized. The router also supports only one or several broadband access methods, such as most reflected only supports ADSL/Cable Modem, which does not supportthe broadband access mode, the user the choice should be based on their own forbroadband access way to understand clearly, of course, the vast majority of currently support all types of broadband access. If broadband access is the broadband, more should pay attention to, the router WAN port best choice can support 100Mbps, because residential broadband is easy to upgrade to 100Mbps in a short time.

 

3, The number of router LAN port

The traditional router usually provides only a handful of early 1, 2 LAN (LAN) switch ports, while the WAN (wide area network) ports usually have more than one, because it is not used to connect LAN, but used to connect different WAN. While the family broadband routerapplication focus is different, it is connected with WAN usually only one or 2, and the LANport is connected with several users demand, so the broadband router are also usually provide 4 to 8 around the switch port, for sharing user connection. In the case of small number of users, users do not need to buy a separate switch or hub, for the user to save the investment of network equipment. So we in the choice of the router, as a home user is usually less than 4 computers, so be sure to choose to provide enough exchange appliedLAN port, for sharing user directly connected. Of course, the broadband router must havemore than one WAN port (for broadband access, such as ADSL or broadband).

 

4 Router, whether to support the NAT service

NAT is the “network address translation”, with this service router can put all the LAN user IP addresses to a single Internet IP address, so as to realize the internal network of IP play a role in shielding, protect LAN users. But the vast majority of the router is to support theservice, need only check the manual or ask the dealer.

 

5 The network management mode

In order to user configuration convenience, now most broadband routers provide Web interface configuration function, user WYSIWYG configuration by ordinary browser, easy. But there are also some brand router but do not provide this kind of management mode, only provide command line router configuration mode, the non professional computer users, is difficult, should pay attention to ask.

 

6 The price of the router

After the above factors, the biggest factor is the price. You should do a comparisons on a router.

 

7 After sale service

 

The router after sale service, such as customer service, warranty replacement period you should understand when you buy a router.
