Description of the problem

Huawei OSN3500 device SSN4EGS4 single board is configured with GE electrical interface, configured with BPS or PPS protection, and the network management reports an error with wrong port type; see the attachment;

Host version 5.21.19.14; network management version T2000V2R7C03SPC004;

Processing

1, OSN3500V1R9 version in the hardware description of the SSN4EGS4 is to support the 1000M electrical interface module; host support this single board;

2, verify the version matching table, network management and host matching, no problem;

3, check the business configuration, found that the main and backup boards are empty boards with no configured services, also no problem;

4, according to the BPS and PPS topic, GE electrical interface protection, V1R9 host began to support, but did not point out in detail exactly which version; and configuration to be configured as a slave mode to be able to;

5, after the final verification, the configuration mode is not a problem, is the host does not support 1000M GE electrical interface protection configuration; the following version can only be:

The BPS of GE electrical interface can be supported in version 5.21.19.22 and above; however, the PPS of GE electrical interface is still not supported, and all versions of this single board are not supported;

6、Configured with a 1000M electrical interface module, the interface is not set to the electrical interface type, directly configure the BPS protection or PPS protection is it feasible? Impossible, the actual plugged into the electrical module, but also configured as a logical optical module, will report MOD_TYPE_MISMATCH alarm, refers to the actual module type does not match the logical type of the module, the business can not pass, not to mention with PPS.

Root Cause

1. The single board interface board configuration electrical interface module is not one-to-one correspondence;

2, the interface type is selected wrong;

3, the host does not support;

Suggestions and Summary

It is recommended to improve the related information and make detailed descriptions of the configuration and restrictions related to BPS and PPS protection, so as to better guide the operation of front-line engineers;
