Problem Description

The T2000V2R7C03SPC003 network administrator creates a VB of bridge type 802.1Q on the N1EMS2 board of the OSN3500 device, and prompts "This command is not supported, error code 38737" when it connects ports, and the ports cannot be connected.

Host version: 5.21.19.22

OSN3500 Fiber Optic Transmission Unit N1EMS2

Processing

1:After uploading data, reconfiguration failure remains;

2: Change the bridge type and the problem still exists. Check the description of the single board which also supports 802.1Q;

3: Check the version of the supporting table host with the single board is also supporting; network management requirements for the R7C02, the site R7C03 should be no problem to use the R8 network management configuration failure remains;

4: Get the relevant data to the R & D analysis, confirmed that the R7C03/R8 network management support the command to set the bridge type, but 5.21.19.22 hosts are not supported. There is a problem with the downward compatibility of the network management;

6: Use R7C02 network management configuration temporary solution, followed by R & D to give a complete solution.

VB can not hook up theroot cause of theport

1: Inconsistency between network management and network element data;

2: 802.1Q type bridge is not supported, only 802.1d or mixed mode;

3: The host does not match with the single board;

4: Problems in the cooperation between the network management and the host;
