Secure Switch Access is a filtering program that prevents unauthorized access to the switch by 
allowing you to define a list of filters and filter points. For Secure Switch Access, filters are 
lists of source traffic that are allowed onto the switch. Filter points operate on 

IP

 protocols 

that include 

FTP

, Telnet, 

SNMP

, 

TFTP

, 

HTTP

, and a custom 

IP

 protocol. Whenever any of these 

filter points is enabled, all filters configured for that protocol are applied to incoming traffic 
using the filter point protocol.

All access violations are logged. If a filtering point is not enabled, it is accessible to all users. 

Use the 

 command to view and configure the database of secure access filters. This 

database includes information on filter names, source 

IP

 addresses, source 

MAC

 addresses, 

and the physical ports receiving data.

checked against a Filter Name to establish authorized access, the 

 fields are not checked.
