CONFIGURING THE SWITCH
not overlap, but still need to communicate, you can connect them by using a
Protocol VLANs – This switch also supports VLANs based on specific protocol types, such as IPX and AppleTalk. When a protocol is bound to a VLAN, the switch will only forward packets carrying the specified protocol tag. However, regardless of the protocol type, remember that traffic must still be passed though a router to reach a different subnet.
Automatic VLAN Registration – GVRP (GARP VLAN Registration Protocol) defines a system whereby the switch can automatically learn the VLANs to which each endstation should be assigned. If an endstation (or its network adapter) supports the IEEE 802.1Q VLAN protocol, it can be configured to broadcast a message to your network indicating the VLAN groups it wants to join. When this switch receives these messages, it will automatically place the receiving port in the specified VLANs and forward the message to all other ports. When the message arrives at another switch that supports GVRP, it will also place the receiving port in the specified VLANs and pass the message on to all other ports. VLAN requirements are propagated in this way throughout the network. This allows
To implement GVRP in a network, first add the host devices to the required VLANs (using the operating system or other application software), so that these VLANs can be propagated onto the network. For both the edge switches attached directly to these hosts, and core switches in the network, enable GVRP on the links between these devices. You should also determine security boundaries in the network and disable GVRP on ports to prevent advertisements from being propagated.
Note: If you have host devices that do not support GVRP, you should configure
