Processing

1. Check and find that the site is using R1CXL

The crossover capacity of CXLLN single board is as follows:

High-order crossover capacity: 15Gbit/s

Low-order crossover capacity: 5Gbit/s

Access capacity: 10Gbit/s

The crossover capacity of our previous Q2 and Q3CXL1 boards is as follows:

High-order crossover capacity: 20Gbit/s

Low-order crossover capacity: 20Gbit/s

Access capacity: 15Gbit/s

The access capacity of R1CXL single board is relatively small, the bandwidth of slot 11 is 622Mbit/s, and the bandwidth of slots 12 to 13 is 1.25Gbit/s. There are many single boards that do not support this, so we need to pay attention to it.

Root cause

1, verify the host network management support N3SL16, with the command line can not be added, completely exclude the network management reasons, is the database error?

Suggestions and Summary

In addition to SL16, SLQ4 and SLT1 can not be configured for R1CXL use. Besides, although the Ethernet single board can be used with R1CXL, the bandwidth with slots is also reduced accordingly, which you can refer to the hardware description manual of OSN1500 for details.
