Problem Description

After the OSN3500 device is configured with TPS protection, it is also carried out through the cross board to detect each service veneer. To determine whether the TPS protection group is normal, it is necessary to query the cross board to detect the 8K clock line of the tributary board and the self-test status.

Alarm information

None

Processing

Perform the related query with the following command

:optp:cross-board number ,0,2e,1,26,13,protection group ID;" where we mainly input "cross-board number" and " protection group ID " .

In which we mainly input "cross board number" and "protection group ID ", the parameters in the middle have no special significance and belong to the fixed query command;

An example of parameter return:

:optp:9,0,2e,1,26,13,1;

Optp cmd 2613

01 01 01 01 01 02 01 00 03 01 01 01

Total records :1

The first parameter in the above return parameter is the protection group ID, followed by the board number of each single board, the 8K clock line status of the single board detected by the cross, and the single board self-test status reported ; the status is 1 for good, 0 for bad ; in this example, you can see that the second parameter behind the 2 board position is 00, which means that the cross does not receive the self-test status reported by 2-PQ1, 1 ,3 board position PQ1 single board self-test information is normal.

Root cause

None

Suggestions and Summary

Supplementary explanation of the return parameters, after the first parameter protection group ID, every three parameters represent the information of a single board, which is more similar to the " :ptp:cross board bit number ,12,cc " command used by the cross board to detect the status of other single boards in the TPS protection of 2500+ devices in the 4.0 platform.
