Protocol-based VLANs enable you to define a packet filter that the Summit 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
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 Summit. 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.
