Protocol-based VLANs enable you to define a packet filter that the BlackDiamond uses
as the matching criteria to determine if a particular packet belongs to a particular
VLAN.
Protocol-based VLANs are most often used in situations where network segments
contain hosts running multiple protocols. For example, in Figure 4-7, the hosts are
running both the IP and NetBIOS protocols.
The IP traffic has been divided into two IP subnets, 192.207.35.0 and 192.207.36.0. The
subnets are internally routed by the BlackDiamond. The subnets are assigned different
VLAN names, Finance and Personnel, respectively. The remainder of the traffic belongs
to the VLAN named MyCompany. All ports are members of the VLAN MyCompany.
