portfilter

Syntax:

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

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.

If no arguments are given, the current settings for each port are displayed.

Example 1:

portfilter2345

portfilter 3 1

Example 2:

portfilter 2 all

portfilter 3 all
