table.
■

corresponding MAC addresses stored in the binding table.
◆
Filter Table – Sets the source guard learning model to search for addresses in
the ACL binding table or the MAC address binding table. (Default: ACL binding
table)
◆
Max Binding Entry – The maximum number of entries that can be bound to an
interface. (ACL Table: 1-5, Default: 5; MAC Table: 1-32, Default: 16)
This parameter sets the maximum number of address entries that can be
mapped to an interface in the binding table, including both dynamic entries
discovered by DHCP snooping (see
“DHCP Snooping” on page 299 ) and static
entries set by IP source guard (see “Configuring Static Bindings for IPv4 Source
Guard” on page 311 ).
