4-4-7. Filtering Configuration
The filtering function in Signamax 065-1600 series is used to filter unwanted
MAC address from accessing the converter based on some simple rules. Signamax
065-1600 series provides three types of filtering function for security configuration.
They are Allowed Forwarding MAC Address, Port Security and Denied Forwarding
MAC Address. You can configure it for different purposes of application. Here we list
two examples for your reference.
Example 1:
Assumes administrator wishes a specified station can only access
the converter from a specified port and the traffic from all other stations is
rejected by that specified port. How should we configure Signamax 065-
1600 series for the case?
Solution:
First, enter the function “Allowed Forwarding MAC Address” to add
an entry with the MAC address of the specified station on the Allowed
Forwarding table of the specified port. The Security Port of the specified
port should be then enabled in the “Port Security” function. Finishing these
processes, the specified port will not allow any other station to access the
converter except the specified station. And if this specified station is moved
to other port, it cannot access the converter, either.
Example 2:
Assumes an administrator wishes to deny a specified station from
accessing the converter, which is to isolate the specified station from the
converter. How should we configure Signamax 065-1600 series for the case?
Solution:
For denying a specified station, it is easy. You just have to use the
function “Denied Forwarding MAC Address” to configure it. Enter this
function and select the <Create New Entry> function to add the MAC
address of the specified station, which is rejected to access the converter.
The Deny Forwarding function is global. It is applied to the whole converter.
