Reboot unexpeted : VFL connected with both DAC and SFP fiber

Switching
1

Hi everybody,

We have strange behavior when we connect our switchs on stack via VFL ports.

If we connected both DAC cable and SFP + fiber cable on stack , slaves reboot again and again. But if we use only SFP we don’t have any problem.

We want to use both because of site’s configuration (multiple floors, and lan connectivy must be enhanced in each floor).

Our stack is composed by 6 chassis (6360 ans 6360-p24x) in auto-vfl mode.

Do you have any idea why this behavior?

thanks!

can you share your swlog messages related to VCM? - have you also tried a different DAC cable?

Hi ,

Thanks for your answer.
We have two DAC types, we think maybe it’s because one of them is a compatible, we’ll try next week.

For swlog, if it’s okay, we’ll waiting the new test.

Thanks again
