We have 2 vlans
vlan 20 & vlan 30
they are both currently able to contact each other but we don't want them to be able to. We have 2 switches too, with these vlans on them.
They should not be able to contact each other on the same switch or going through another switch.
Would we have to set up an ACL to stop this or are there commnads we can use to set up such paramiters when we set up VLAN's
edit: trunking is enable on both switches
