Whether bidirectional cross-connections can be configured using the command line interface on equipment running on the 5.0 platform

18

If the equipment runs on the 5.0 platform, you cannot directly configure bidirectional cross-connections using the command line interface. Instead, you need to configure two unidirectional services. Queried cross-connections are also unidirectional.

Precautions for OSN 6800 to use command lines to delete board optical cross-connections or create single-site optical cross-connections
(1) The single-site or board optical cross-connections of other wavelengths are successfully created on the NMS. Therefore, the system control board fault or ROAM fault of the optical-layer scheduling board is ruled out. (2) When the cfg-get-e2eoxc:0,0 command is used to query the single-site optical cross-connections, the optical cross-connection of the wavelength on the ROAM is 0000, which is abnormal. The state should be one of active, adding, and deleting. (3) When a command line is used to create the single-site optical cross-connection of the wavelength, the optical cross-connection is successfully created. In addition, the single-site optical cross-connection of the wavelength can also be successfully deleted from the NMS. (4) Check the operation records of the onsite engineer and find that the procedure is as follows: Check the board optical cross-connection of the wavelength à Create the single-site optical cross-connection of the wavelength à Query the board and single-site optical cross-connections of the wavelength. The wavelength is present on both the board optical cross-connection and single-site optical cross-connection. Then, you can delete the board optical cross-connection and verify it. (5) If the board optical cross-connection is deleted using a command line but no verification is performed, services will not be interrupted when the board optical cross-connection is in the deleting state. If a single-site optical cross-connection is created at that time, the board optical cross-connection will become the active state. After the verification command is successfully delivered, the wavelength cannot be found in the board optical cross-connection and it can be queried only in the single-site optical cross-connection. (6) Because the onsite engineer found the wavelength both in the board optical cross-connection and single-site optical cross-connection, the engineer falsely determined that the optical cross-connection was not successfully deleted and then deleted it again. As a result, optical cross-connections on the NE software side are incomplete.

Whether cross-connections can be configured between subracks
No, cross-connections cannot be configured between subracks because no cross-connect board can be configured crossing subracks.

Can the VCN3000 platform be connected to the IVS C30 platform?
The VCN3000 can be connected to the IVS C30 through GB/T 28181 to implement resource sharing through device sharing. For details about how to connect the VCN3000 to the IVS C30 platform, see the eSpace VCN3000 Product Documentation. �� Visit the Huawei Enterprise Technical Support website and download the eSpace VCN3000 Product Documentation of the required version. �� The IVS C30 must be upgraded to eSpace IVS V100R001C30SPC113 or later. �� It is recommended that the VCN3000 be upgraded to eSpace VCN3000 V100R001C01SPC128.

Method used to develop performance statistics by using the common line interface
You can perform the following operations to develop performance statistics by using the CLI: 1. Fault location and rectification You can use the CLI to manually collect performance data. 2. Solution You can collect performance data through ports and LUNs. The following commands are entered and performed in sequence in CLI mode and their displayed results are saved in logs. a. Collecting data by port OceanStor: admin> chgstatswitch -o -p OceanStor: admin> statperf -p Enter the above commands at an interval of 3s for 10 times. OceanStor: admin> chgstatswitch -c -p Based on port statistics, the maximum latency is not more than 1.5s, the average latency is not more than 300 ms, and I/O processing is in normal state. b. Collecting data by LUN OceanStor: admin> chgstatswitch -o -l OceanStor: admin> statperf -l Enter the above commands at an interval of 3 seconds for 10 times. OceanStor: admin> chgstatswitch -c -1
