we bought 2xms210 with 2x 40gb stacking cable and follow the guide to configure a physical stack
https://documentation.meraki.com/MS/Stacking/Switch_Stacks
both switches have been connected to meraki cloud with one uplink each and the latest firmware MS 14.32 has been installed.
after powering down we connect both cable as explained (crossed) with only one uplink on one member.
unfortunately after the boot the stack interfaces are still down and there no potential stacking detected to create the stack, we try to create it manually but did not work.
we had to connect again the uplink on the other member and remove the stack configuration.
any suggestions?
thanks
Would try to reseat the stack cables(make sure they pushed in all the way) or try another stack cable.
we have only 2x stack cable and we reseat them several times but nothing change
Do the stacking ports come up green?
What I do is:
I know it isn't the prescribed order but it always seems to work for me...
Do the stacking ports come up green?
no
What I do is:
Are the cables clicking in? I've never had them not go green on the dashboard...
yes they're connected firmly.
Do you have any other QSFP+ DAC cables, or any other devices that have a QSFP+ socket so you could test to see if you have faulty cables or (less likely) faulty sockets. Have you tried connecting the cables from one port to the other on the same switch to see if you get anything on the dashboard? I'm presuming you just have a black rectangle as below:
You should see the connector type and green like this:
we have 2 cables connected crossed but all the 4 ports are disconnected.
cables are cisco original (MA-CBL-40G-1M)
unfortunately we do not have other other QSFP+ DAC cables or socket.
we'll try to connect the cables one by one and see if it change.
SOLVED: we were able to get 2x new stack cable and the links went up correctly
thanks to cmr and ww
Once I had the same problems with stacking cables.
