8.4.3.1.11 BRIDGE SET INTERFACE PORTFILTER

Syntax BRIDGE SET INTERFACE

{<name>|<number>} PORTFILTER {ALL|<port>}

Description This command controls the bridge’s forwarding and broadcasting behavior. It allows you

to set a portfilter on a bridge interface to determine which port or ports multicast and

unknown packets should be forwarded to.

This command sets one destination port at a time. If you want to forward packets to sev-

eral ports, enter a bridge set interface portfilter <port> command for each port. If you

want to forward packets to all ports, enter the command and specify the all value.

Note: If a unicast packet is received by an interface with a portfilter set to all, the portfilter rule is

ignored. The unicast packet is still only sent to one port.

Note: If the bridge itself is attached to the router, the bridge itself will always forward to all ports and

will always be forwarded to by all ports.

Options The following table gives the range of values for each option that can be specified with

this command and a default value (if applicable).

Example --> bridge set interface bridge1 portfilter ethernet
