Meraki MS - Port Isolation

[Pavan_Pawar]

Hello Experts,

On switch, I have 4 interfaces that are part of VLAN 100 and interfaces 1 and 2 have been put in Isolation but still they can reach interfaces 3 and 4.

What something that's needs to be checked?

Isolated ports are isolated against each other, but not against the non-isolated ports. If it would, you couldn't reach your upstream gateway. You need to implement other security measures like different VLANs terminated and filtered on the firewall or switch ACLs.

[Pavan_Pawar]

so the isolated ports can communicate to non-isolated ports 

and Isolated ports can not communicate to isolated port

Is It the right understanding?

This is expected behaviour.

Have a look at the following doc. It has some good explanations and examples around switch port isolation.
