10-6 Bridge Commands
The stations on a logical network belong to one group; however, a station can belong to more than one group.
Users of one group are not allowed to access the resources of other groups and a higher level of security is
achieved. This isolates the subscribers from one another and prevents a subscriber from discovering the resources,
for example, shared drives or printers, of another subscriber.
In a port-based VLAN, the allowable outgoing port(s) of each incoming port must be defined. Ethernet frames are
forwarded according to these rules. Therefore, if you wish to allow two subscriber ports to talk to each other, for
example, between conference rooms in a hotel, you must define the egress port (outgoing port) for both ports. An
egress port is an outgoing port, that is, a port through which a data frame leaves. Port-based VLANs are specific
only to the switch on which they were created.
The factory default settings for the port-based VLAN of the line card are:
- Bridge port 1 (Ethernet uplink port) allowed to all bridge ports
- Bridge port 2 (DSL port 1) allowed to bridge port 1 (Ethernet uplink port) only
- Bridge port 3 (DSL port 2) allowed to bridge port 1 (Ethernet uplink port) only
