Problem Description

A newly built OSN3500 device cannot be logged on or PINGed through in the field.

Alert message

None

Processing

1, the scene through the portable machine with a network cable directly connected to the device can not PING through, replace a number of network cables are so, while the portable machine can be connected to other devices can be logged on normally, can be excluded from the network cable, portable machine and other external reasons;

2, by other devices through the ECC can log on to the device, the device can be alarms, performance queries and other respective operations, can further confirm that the device itself communication problems;

3, OSN3500 device has dual master control, master and backup reversed, retain a master control ( 17/18 are trying), remove other single board only retain a master control and other operations, are unable to solve the problem, can be ruled out that other single board problems lead to the possibility of the problem;

4、Apply for a new master control and an AUX single board, replacement are invalid;

5, with cfg-set-oamport query ETH port status, confirmed that it is open, but also carried out the operation of closing and opening, invalid;

6, consult the R & D, R & D to provide a data collection tool to collect data, after analyzing the reason is: Ethernet port is not UP up, not generate routing information, only two routes, so can not ping through;

7、Use cm-get-lanaccess query to confirm the status is close, set to open can be normal after login. The problem is solved.

Root cause

1、Network cable problem;

2. Failure of the main control board or AUX single board;

3、Device subrack problem;

4、Software setting problems

Recommendations and Summary

Command line parsing:

Name cfg-set-oamport

Function Sets the switch for the maintenance port

Command Level System Monitor

Open scope User level

Version 5.36.17.XX&5.21.17.XX

Input Format :cfg-set-oamport:PortType, state; number of parameters = 2, parameter block repeat

Input parameters Parameter position Parameter meaning and value

1 Port type

COM: COM port

ETH: ETH port

OAM: OAM port

F_f: F&f port

2 Port status: open / close (port default : all ports are closed exceptETH port which is open)

Name cm-set-lanaccess

Function Sets the Ethernet access control to close or open the Ethernet driver.

Command Level System Maintenance

Open Scope User Level

Version OSP Full Version

Input format position definition, number of parameters = 2, repeat mode: no repeat

Input parameters Parameter position Parameter value

1 LAN NO: Ethernet number; numeric format;

2 STATE: Ethernet allow/disallow access flag

Customized format, string

close - forbidden ( 0 ), open - allowed ( 1 )

Output format Error code

NSERR_LAN_ERR_PARA: parameter error

NSERR_LAN_DBF_FAIL: database operation error

NSERR_LAN_FUNCALL_FAIL: function call error

NSERR_LAN_SUCCESS: Successful operation

Example :cm-set-lanaccess:0,close;

Cautions 1. Do not use this command lightly, or you will not be able to use the management terminal! And after closing the Ethernet access, the extended ECC function working through Ethernet will also not work!

Remarks 1. At present, only the case of setting the Ethernet number to 0 is allowed.

Where cm-set-lanaccess corresponds to the entrance of the Ethernet access control on the network management, the command is stored in the library, if set to close, unplugging the board can not be restored.
