The Node option controls the forwarding of packets based on the source node addresses. Type specific node filters by specifying the 6-byte infrastructure address of the node or by specifying its IP address. If the IP address is used, the bridge determines the infrastructure address associated with the IP address and uses it for the actual filtering. You can filter packets based on the source address in the received packet. The Ethdst option sets a default that applies to those packets whose addresses do not have entries in the filter table.
Options are forward or discard .
Source address filtering is forward by default. The Display option allows you to view the table of controlled addresses. The filters are stored in the association table so that they can be accessed quickly. The display of the filters follows the format of the normal association display. At the end of each line the filter action for each address is displayed.
