Handling Process

1、Use “disp cdev slot 5” of hidden view  we found  that  the board type was “BoardExtType 3”, which is correct.
2、Use “dis dsms variable slot 5′ we found the info like this “BoardExtType 7” which should be modified.
3、Modify the board type like this,set boardid <slot-id> <type-id>
[S9303-hidecmd]set boardid 5 3
2、Reset CBUS with commands
[S9303-hidecmd]reset cbus slot  5 cold
3、Renew  the software and SDR file of CBUS.
<S9303>upgrade slavempu jtag startup canbus_app
<S9303>upgrade slavempu jtag startup canbus_sdr
5、Then temperature alarm disappeared, Fan speed can be automatically regulated to 27%.

Root Cause

1、Backup SPU (Slot 5)’s board type is incorrect  and  lead to temperature alarm.
2、The fan run with 100% speed because of the  temperature alarm  and can’t regulate it manually.
3、Modify the board type and reset CBUS, The problem can be solved.

Suggestions

If there is a alarm refer to temperature he FAN will run with 100% speed.  But sometimes  this alarm will be caused of other reasons, so we would better deal with it  immediately  to make the fun speed become normal.

Scenario 1: ODU1 tributary mode (cascading)

Overview of the Working Modes

This section describes the board working mode and port working mode. A specific service signal flow of a board is available when the board working mode and port working mode are set to specific values.

Board mode

As shown in Table 1, the TN11TOM boards support the cascading and non-cascading modes.

Table 1 Board mode of the TN11TOM board
Board mode Description
Cascading mode
  • A maximum of eight multi-rate (< 2.5 Gbit/s) client-side services can be input to the TN11TOM board through the SFP module on the client side.
  • The services are then multiplexed into different timeslots of one or two ODU0 services or one ODU1 service.
  • Each group of ClientLP ports, for example, 201(ClientLP1/ClientLP1)-1 to 201(ClientLP1/ClientLP1)-8 ports, can access a maximum of eight client-side services.
Non-cascading mode
  • A maximum of eight multi-rate (< 2.5 Gbit/s) client-side services can be input to the TN11TOM board through the SFP module on the client side.
  • The services are then multiplexed into different timeslots of one to eight ODU0 services or one to four ODU1 services.
  • Each group of ClientLP ports, for example, 201(ClientLP1/ClientLP1)-1 to 201(ClientLP1/ClientLP1)-4 ports, can access a maximum of four client-side services.

Port Working Mode

The TOA board supports five working modes listed in Table 2. You can set the port working modes on the NMS.

Table 2 Mappings between the working modes and the service mapping paths
Board Working Mode Configuration Scenario Port Working Mode Mapping Path
Cascading mode Scenario 1: ODU1 tributary mode (cascading) N/A OTU1/Anya->ODU1
Scenario 2: ODU1 tributary-line mode (cascading) N/A OTU1/Any->ODU1->OTU1
Non-cascading mode Scenario 3: ODU1 tributary mode (non-cascading) N/A OTU1/Any->ODU1
Scenario 4: ODU1 tributary-line mode (non-cascading) N/A Any->ODU1->OTU1
Scenario 5: ODU1 tributary-line mode (electrical regeneration board) N/A OTU1->ODU1->OTU1
a: “Any” in the table indicates the client-side service supported in the corresponding application scenario.

S27 & 37 & 57 series switches WEB management interface configuration method

Issue Description

Huawei S2700 series/S3700 series /S5700 series switches WEB management interface configuration method

Alarm Information

None

Handling Process

First, configure the host and switch interoperability
1.  Created VLAN100
[Quidway] vlan 100
2.  VLAN interface 100 configured IP address
[Quidway] interface vlanif100
[Quidway-Vlan-interface100] ip address 10.1.1.132 255.255.255.0
3.  Entry the uplink port E0/24 , configure it as access port, and allow VLAN100 passing.
[Quidway] interface gigabitethernet0/0/1
[Quidwaygigabitethernet0/0/1/24] port link-type access
[Quidwaygigabitethernet0/0/1] port default vlan 100
4. Configuration PC address and the switch management address in a same segment, setting the gateway as the management address

Second, upload the WEB management file to the switch
1.  Execute the command system-view, to enter the system view.
2.  Execute commands ftp server enable, enable the FTP service.
3.  Execute the command aaa, enter the AAA view
4.  Execute command local-user user-name password {simple | cipher} password, configure the FTP user name and password.
5.  Execute the command local-user user-name ftp-directory directory, configure FTP user access path.
6.  Execute the command local-user user-name service-type ftp, configure FTP login user service type.
7. Execute the command local-user user-name privilege level 3 set permissions.
8.  In the Cmd view of the PC, Execute the command ftp ip-address, enter the user name and password to log on to the switch.
C: \> ftp 10.1.1.132
Connected to 10.1.1.132.
220 FTP service ready.
User (10.1.1.132: (none)): client
331 Password required for client.
Password:
230 User logged in.
ftp>
In the FTP view, execute the command Put local-filename upload the Web page file on the PC (for example: web.zip) to the switch.
ftp> put web.zip
200 Port command okay.
150 Opening ASCII mode data connection for web.zip.
226 Transfer complete.
ftp: send 251,047 bytes, with 3.36Seconds of 74.74Kbytes/sec.
ftp>
—- End

Third, load WEB file
Execute the command system-view, to enter the system view.
Execute the command http server load file-name, loading the Web page file.

Fourth, configure HTTP account
Execute the command system-view, enter the system view.
Step 1 Execute the command the http server enable, enable the HTTP service.
Step 2 Execute the command aaa, enter the AAA view.
Step 3 Execute the command the local-user user-name password {simple | cipher} password, configure HTTP user name and password.
Cipher form password is the best in the actual configuration, user name and password do not set too simple, in order to guarantee security.
Step 4 Execute the command local-user user-name service-type http, configure user admin access type for HTTP.
Step 5 Execute the command the local-user user-name privilege level 3, set permissions.
Step 6 Execute the command quit and return to the system view.
Step 7 (Optional) Run the http timeout timeout ,configured HTTP session time-out, the default session timeout is 30 minutes.

Five, landing WEB network management
Open Web browser on PC, enter S5300 management IP address (have a reachable route between the PC and S5300) in the address bar, press the Enter key will display the login dialog box. Input the setting Web management account and password before, enter the code and select the language of the Web NMS.
a) login interface
Before you click “login”, you can select “remember my password”, so the next time you log on to the system, enter your user name and password will automatically match with the user name.

Can SSN4EGS4 be able to add in OSN 3500 with V1R6 software?

V1R6(5.21.16.13) is not included in SSN4EGS411, so N4EGS4 can not be used in that OSN 3500 with V1R6, the way to solve is:

1, change SSN4EGS4 into SSN1EGS4

2, upgrade system software to V1R8 or later version.

Method 2 is suggested, which is better for future expansion, compatible more boards.
