| alert ip any any -> any any (msg:"Packet has 3 VLAN layers"; vlan.layers:3; sid:1;) | ||
| alert ip any any -> any any (msg:"Packet has more than 2 VLAN layers"; vlan.layers:>2; sid:2;) | ||
| alert ip any any -> any any (msg:"The number of layers in the packet is not 1"; vlan.layers:!1; sid:3;) | ||

vlan.layers:0 meaning no vlan in packet
vlan.layers:>0 meaning there is a vlan header in the packet?
