Figure 9-3 Example of Modified VLAN Port 3

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

9.7Tagged 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 5.5.5) and the 802.1Q VLAN commands (see Chapter 10 ) to configure VLANs or PVIDs with multiple ports.

9.7.1FPVID Command

Syntax:

192.168.1.1 bridge> fpvid [<port> <vid>]

where

<port> = The port number on the network module. Port 0 is the CPU’s port, port 1 is the Ethernet port and ports 2-9 are the bridge ports on network module modules. These are logical ports.
