(source-filtering | no-source-filtering);
Statement modified in Junos OS Release 9.2.
For redundant Ethernet interfaces, enable the filtering of MAC source addresses, which blocks all incoming packets to that interface. To allow the interface to receive packets from specific MAC addresses, include the source-address-filter statement.
If the remote Ethernet card is changed, the interface cannot receive packets from the new card because it has a different MAC address.
By default, source address filtering is disabled.
