If security mode is disabled, and the destination address is known, the packet is forwarded on the appropriate port. If the address is not known, the packet is sent (flooded) on all the other ports. For more information, refer to 11.8.5, ªFiltering for Bridging Functionsº on page270.

Custom Filtering

This option allows you to enable or disable custom filtering for the packets received on this port. When this parameter is enabled, the Custom Filter Test and Custom Filter Statement Table will specify the tests and actions to be performed. For more information refer to 11.8.5, ªFiltering for Bridging Functionsº on page 270.

Source Address Learning

If enabled, the Multiprotocol Interconnect module will search the filtering database for the source address of each received packet. If the address in not found to be in the database, it will be added to the database along with the number of the port on which the packet was received.

Source Address Filtering

If enabled, the Multiprotocol Interconnect module will search the filtering database for the source address of each received packet. If the address in not a fixed entry (manually entered by the user in the filtering database), then the packet is discarded. Note that when security mode and source address filtering are both enabled, the bridged traffic is restricted to between the stations that have fixed entries in the database.

Always Accept Multicast

This parameter is used to allow the bridging of multicast packets when the security mode is enabled. If this parameter is disabled and the security mode is enabled, the multicast packets will be discarded. This parameter has no significance when the security mode is disabled.

Note: Transparent Bridging Port Parameters panel for token-ring ports is identical to that of the Ethernet ports which is shown here.
