GVRP Commands. Table 4-1 describes GVRP commands.
Protocol-Based
VLANs
Protocol-based VLANs enable you to define a packet filter that the
switch 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 switch. 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.
