CRS326-24S+2Q+RM "Stacking" 2 via QFSP no connection

Tue Feb 11, 2020 9:43 pm

Hi all,

I have bought 2 CRS326-24S+2Q+RM with two MikroTik 1m cables.
My plan was to replace the two ES-16-XG as core switches.
Not much features are needed.
- Bootmode: SwOS
- About 300 VLANs added
- IP assigned
- Hostname assigned
- Bride hex value entered
- RSTP on on all ports
Thats it.

So now my issue:
As soon as I interconnect the switches via the QSFP cable from MikroTik there is not traffic passing from switch one to switch two. If I connect them via SPF+ and LC-LC cables no issues. Traffic passes on and RSTP configures it self correctly.

Did you ever get to the bottom of this? I've just bought 2 of these switches and am about to do the same.
