Problem Description

The ONS3500 device is upgraded from version 5.36.18.50 to version V1R8C02SPC200 to solve the N2EGS2 single board bandwidth drop problem.After the upgrade, the single board bandwidth problem is still 1.25G. VCTRUNK25-48 still cannot configure the service. 2.5G bandwidth cannot be configured.

Alarm information

None

Processing

1. After the software version is upgraded to V1R8C02SPC200, remove the SSN2EGS2 single board service.

2、Delete SSN2EGS2 logical single board and re-add SSN2EGS2 logical single board

3. Reconfigure the SSN2EGS2 service.

4. The bandwidth is restored to 2.5G, and VCTRUNK25-48 can configure services normally.

Root Cause

SSN2EGS2 single board original data in the host configuration has been fixed, the bandwidth mode is fixed in the host side, so after upgrading, the bandwidth does not change still 1.25G. you need to delete the logical single board, re-add the logical single board, SSN2EGS2 single board in the host side of the current modeling. The bandwidth is restored to 2.5G.

Recommendations and Summary

OSN1500 is upgraded from version 5.36.18.50 to version V1R8C02SPC200 to solve the problem of bandwidth drop of N2EGS2 veneer, after upgrading, it is necessary to delete and re-add the N2EGS2 logical veneer, the original data of N2EGS2 veneer has been fixed in the configuration on the host, and the bandwidth modeling is fixed on the host side, so there is no change in the bandwidth after upgrading. You need to delete the logical single board and re-add the logical single board, and the N2EGS2 single board is modeled on the host side. The bandwidth is restored to 2.5 G. Attention is required when upgrading.
