In a bureau, when an engineer performs protection subnet status on a multiplexed segment ring grouped by OSN3500 devices, he finds that no matter whether he queries the multiplexed segment status in the Network Element Manager or in the protection subnet network management prompts the error: Command Error (which indicates that the command is not supported by the veneer), Error Code: 38751.

The host version is 5.21.17.31.

Webmaster version is V2R5C01b01cSPC007.

1. First, use the command line :cfg-get-rmsstate to query the state of the multiplexing segment of the network element and find that it can be queried, so it is suspected that the problem is with the network administrator.

2, and then in the network management query other Metro 1000 and other devices found to be able to query normally, no error, query other OSN 3500 devices (version is: 5.21.12.43/5.21.13.47) can also be queried normally, no error, to rule out the network management problem.

3, suspect that the network management and host coordination problems, return to the EMS.log log analysis can be found in the network management to return such an error: NSCMD_CFG_GET_MSSPR_SWSTA_02, corresponding to the host to send the command is: cfg-get-rmsstate-new

4. having the site directly issue this command prompts:

:cfg-get-rmsstate-new:1;
failed! cmd:0x853f error:0x975f NSERR_BDRSP_BAD_CMD

The OSN 3500 device's multiplexing segment protocol is on the cross-board, so to query the multiplexing segment status, you need to query the cross-board; the host of the R7 supports this command, so the problem should be that the cross-board doesn't support this command!

5, query the site of the cross board version 2.14, this version is supporting the R2 host, the original site think that we should be ready to replace the SXCS cross board, in order to save trouble only the host upgraded to the R7 without upgrading the cross board. After upgrading the cross board to version 6.31, the problem was solved.

1、Network management problem

2, host problem

3、Network management and host with the problem

4、Other problems

OSN3500 transmission equipment is required to version strong matching, so when upgrading the host, cross, line and other single boards to upgrade all matching!
