Handling Process

A:

00001. Please check the configuration file blow first:

/opt/U2000/server/etc/conf/logsvc.xml
In this file ,there have content as below:
<syslog name=”syslogReport”>
<logType name=”41″>
<!– Report switch: 0 – Off; 1 – On. The switch is turned off by default. –>
<param name=”syslogReportFlag”>1</param>
<!– Report level control: Only the logs at the same level or a higher level are reported. The default value is 2 (Warning). –>
<param name=”syslogReportLevel”>2</param>
</logType>
<logType name=”42″>
<!– Report switch: 0 – Off; 1 – On. The switch is turned off by default. –>
<param name=”syslogReportFlag”>1</param>
</logType>
<logType name=”43″>
<!– Report switch: 0 – Off; 1 – On. The switch is turned off by default. –>
<param name=”syslogReportFlag”>1</param>
<!– Report level control: Only the logs at the same level or a higher level are reported. The default value is 1 (Minor). –>
<param name=”syslogReportLevel”>1</param>
</logType>
</syslog>
Please confirm the Flag of logReport is ‘1’ or ‘0’
If the flag is ‘0’ ,please change it to ‘1’

00001. Then run the command below to import it to database

#SettingTool -cmd import -file /opt/U2000/server/etc/conf/logsvc.xml 
Then we need to restart the U2000 server to let the configuration be effect

Root Cause

we have downloaded and installed a syslog application on 3rd party server, but we  is unable to receive logs from U2000, when we started

WireShark to trace packets, customer found that the  server does not receive anything from U2000, so we suspects that we  need to do

addiontional config  beside adding the information to the “Forwarding Server” .

When Display Change of Service Ports and Service Failure in the MA5600T?

Keywords: OLT, MA5680T ,MA5683T, Access network

Summary:

GEM ports are added in xPON distributed mode but they are not bound to an ONT.

After the distributed mode is changed to the profile mode, these GEM ports are still

in the system and become distributed GEM ports.

In V800R006C02, if the system has distributed GEM ports, redundant data is

generated. As a result, display of service ports changes and services fail after the

system is upgraded from a version earlier than V800R009C00 to V800R009C00

or a later version. These two problems affect the Internet access service and may

occur on a large number of devices.

[Problem Description]

Trigger conditions:

1. In V800R006C02, the system changes from the distributed mode to profile mode.

2. The system has GEM ports that are not bound to an ONT.

3. The system is upgraded from V800R006C02 to V800R009C00 or a later version.

There is a high probability that display of service ports changes and services fail when

these three conditions are met.

Symptom:

The ONT ID and GEM index of a service port cannot be displayed, but the GEM port ID

is displayed. As shown in the following query result, VPI is displayed as -, and services fail.

MA5600T(config)#display service-port port  0/4/0

{ <cr>|autosense<K>|ont<K>|sort-by<K> }:

Command:

display service-port port  0/4/0

Identification method:

Check whether the system has a distributed GEM port.

MA5600T(config)#display current-configuration section gpon

{ <cr>||<K> }:

Command:

display current-configuration section gpon

[MA5600V800R010: 5900]

#

ont-srvprofile-id 101 desc “ONT_NO_DESCRIPTION”

ont port native-vlan 0 1 eth 1 vlan 1 priority 3

#

return

If the configuration in red is displayed in the command output, the system has a

distributed GEM port. (Normally, GEM Port add is not displayed in GPON

interface mode.)

 

[Root Cause]

In V800R006C02, if the system has GEM ports that are not bound to an ONT

and the system changes from the distributed mode to the profile mode, these

GEM ports become distributed GEM ports. However, these GEM ports should

have been changed to be GEM ports on a line profile for management and usage.

Distributed GEM ports trigger disorder and redundant data. Consequently,

the system has two identical GEM port IDs (the GEM port ID should have

been unique), between which, one is applied by the distributed GEM port and

the other one is applied by the line profile according to the ONT ID and GEM index.

In versions earlier than V800R009C00, the system saves the ONT ID and GEM

index of a service port, displays them and generates corresponding configurations

directly. However, in V800R009C00 and later versions, the system supports

expandability between modules so that the system queries the information about

a service port based on the GEM port ID and displays the query information.

Because of distributed GEM ports in the system, the GEM port ID is not unique

and resources occupied by a distributed GEM port may be queried. Then,

configurations are generated based on these resources. As a result, problems occur.

 

[Impact and Risk]

In the preceding scenario, upgrades will be affected. For example, if the system is

upgraded from V800R007C00 to V800R011, configurations will be incorrect and

services will fail. These problems may occur on a large number of devices.

 

[Measures and Solutions]

All distributed GEM ports in the system need to be deleted. The following uses

slot 4 as an example to delete all its distributed GEM ports.

Recovery measures:

1. Query distributed GEM ports.

MA5600T(config)#display current-configuration section gpon

{ <cr>||<K> }:

Command:

display current-configuration section gpon

What Is the Calculation Method for Load Balancing of the Upstream Aggregation Ports of the MA5680T?

Issue Description

Q:
What is the calculation method for load balancing of the upstream aggregation

ports of the 5680T?

Alarm Information

Null

Handling Process

A:
In the egress-ingress mode: The XOR operation is performed for the lowest three bits of the

source MAC (SMAC) and the destination MAC (DMAC). A residual is obtained by dividing

the XOR result by the number of aggregation ports. The residual value indicates the egress ID.
Example:
SMAC: 0000-1111-aabb, binary numeral corresponding to the lower 1 byte bb: 10111011,

lower 3 bits: 011
DMAC: 0000-1111-ccdd, binary numeral corresponding to the lower 1 byte dd: 11011101,

lower 3 bits: 101
Two aggregation ports exist.
The calculation methods are as follows:
The XOR operation is performed between 011 and 101 (the bit is set to 1 when the

corresponding bits of two operands are different; otherwise, the bit is set to 0 in the following way):
0 1 1
1 0 1
——-
1 1 0
The calculation result is 110 and the corresponding decimal numeral is 6.
At last, the residual 0 is obtained by dividing 6 by 2, then port 0 serves as the egress.
In the ingress mode: A residual is obtained by dividing the lowest three bits of the source

MAC (SMAC) by the number of aggregation ports. The residual value indicates the egress ID.
Example:
SMAC: 0000-2222-abcd, binary numeral corresponding to the lower 1 byte cd: 11001101,

lower 3 bits: 101, corresponding decimal numeral: 5
If two aggregation ports exist, the residual 1 is obtained by dividing 5 by 2. Then, port 1

serves as the egress.

How to Install SLQ4 board on slot 1 to slot 4 in OSN 3500?

Issue Description

SLQ4 board is hardly fully utilize in slot 1 to slot 4 in OSN 3500 although

the slot capacity can support until 5G.
NG-SDH manual:
When the cross-connect capacity is 80 Gbit/s or 200 Gbit/s(S/I XCS),

for the board housed in any of slots 1–4 and 15–16two optical interfaces

can be configured. For the board housed in any of slots 5–8 and 11–14, four

optical interfaces can be configured.

Alarm Information

NULL

Handling Process

The Slot 1 to 4 of OSN 3500 was created for the utilization of the smaller capacity

service board. So SLQ 4 is pretty suggested on slot 4 above .

Root Cause

The cross-connect board (N1E/IXCSA/B) supports two compatible backplane rates

of 622M and 2.5G. Other boards support only one fixed backplane rate. The N1SLQ4

needs 4 buses at a rate of 622M. The cross-connect board (N1E/IXCSA/B) has two

buses in slots 1–4 and 15–17, four buses in slots 5, 6, 13 and 14, and 16 buses in

slots 7, 8, 11 and 12. Therefore, the SLQ4 can be installed only in for 2 optical boards

which can connect to 2 buses.
The cross-connect board supports two compatible backplane rates of 622M and 2.5G.

Other boards support only one fixed backplane rate. Hence, consider both the access

capacity of each slot and the bus distribution of the cross-connect board for board

installation. This method also works for other line boards.

Suggestions

The backplane designed can be improved for this situation to giving customer more

option for utilization on different capacity service board on the sub rack OSN .
