Configuring Source Address Filtering
Source address filtering allows the bridge to prevent packets containing a specific
source address from traversing the bridge. You can use source address filtering to
prevent some stations from transmitting on the ATM WAN link. This type of
filtering is useful for preventing specific stations in a common protocol group on
the Ethernet LAN from transmitting bursty and useless network data across the
bridge and onto the WAN.
