This area of the Catalyst Filter Tables contains a list of MAC Þlter entries. 
Double-click a table entry to access an entry-speciÞc Filter MAC Table view. 
This view allows you to modify the information presented in the table. The 
MAC Table and its corresponding entry-speciÞc views provide the following 
information:

Module
Displays the unique integer identiÞer of the module where this port is located. 
This number is the same as the slot number in which the module is installed. 

Port
Displays the unique integer identiÞer of this port within its module. This 
value is determined by the location of the port on the module.

Address
Displays the MAC address to which the source and destination MAC 
addresses of packets are compared. If the source or destination MAC address 
equals this value, a match occurs. If ÒDenyÓ is speciÞed in the Type Þeld and a 
match occurs, the packet is dropped. If at least one MAC address Þlter is 
speciÞed with ÒPermitÓ and a match does not occur, the packet is dropped.

Type
Displays the type of action this Þlter will cause. Selecting ÒInvalidÓ removes 
this Þlter from the table. Selecting ÒDenyÓ causes packets whose source or 
destination address matches the MAC address speciÞed in the Address Þeld to 
be dropped. Selecting ÒPermitÓ causes all packets whose source or destination 
address does not match the address speciÞed in the Address Þeld to be 
dropped.
