The following figure illustrates that port 1 (the Ethernet port) is linked to ports 2 (DSL port 1) and 3 (DSL port 2).
Ports 2 (DSL port1) and 3 (DSL port 2) are also linked to each other. Or, in other words, the following figure is a
result of the following commands:
192.168.1.1 bridge> portfilter 2 1 3
192.168.1.1 bridge> portfilter 3 1 2

Tagged Ethernet Frames Commands (Fast Mode)

The network module's fast mode makes use of the "tag" subset of the IEEE 802.1Q standard to identify the source
port of an Ethernet frame and speed traffic through a service gateway. In this way, the source port of a frame can
be recognized across switches. Fast mode reduces overhead by basing the forwarding decisions on the 802.1Q tag
instead of checking and filtering MAC addresses. Fast mode allows only one port per PVID. Use normal mode
(see 23.3.5) and the 802.1Q VLAN commands (see Chapter 31 ) to configure VLANs or PVIDs with multiple
ports.
