3.10 portfilter

3.10.1 Syntax

portfilter [<source port> all|<destination ports>]

3.10.2 Description

The portfilter command allows control over the bridge’s forwarding and

broadcasting behaviour. By default, when a multicast or an unknown packet is

received on a port (referred to above as the source port), it will be forwarded to all

other bridge ports (referred to above as the destination ports).

Each bridge port may have its behaviour modified separately. The first example

below configures the bridge so that packets arriving on port 2 will only be forwarded

to ports 3, 4 and 5, and packets arriving on port 3 will only be forwarded to port 1.

All other ports retain their default behaviour.

Note that this command does not force packets arriving on the source port to be sent

to all specified destination ports. The bridge retains its learning behaviour, so unicast

packets, once their destination is known to the bridge, will still only be sent to one

port. Note also that the bridge itself (for example when attached to the IP router) will

always forward to all ports, and will always be forwarded to by all ports.

The default behaviour can be restored by calling this command with the argument all,

as shown in the second example.

The ports are specified as integers, as displayed by the device list command. When

using this command in the initbridge configuration file, ports are numbered in the

order in which the device add commands are given, starting from 1.
