Connecting three Catalyst 9300 with each other

[alsaily]

Hi All,

   As the attached Wiring diagram, We have 3 Cisco catalyst 9300, two at site no. 1 and the other at site no.2 connected with dark fibre. 

can we stake the three switches with each other, on-site no1 with the stacking kit and on-site no 2 with the SFP?

Is it impossible? or only two with the stacking kit and the other with the trunking port with the SFP?

Thanks

Hi,

Is it impossible? or only two with the stacking kit and the other with the trunking port with the SFP?

The stacking cables are usually up to 3 meters. By default, each switch comes with a 50-centimeter cable. So, if the 2 switches are in closed proximity in site-1 you can stack them and then use the dark fiber and trunk the stack to the other switch in site 2

No stacking can be done here, you can port-channel or trunking for Layer 2

Hello

The distance is irrelevant tbh the stack and single switch will just see each other as an interconnected trunk, so yes it is viable.
