4.9.4 Port Security

The switch also supports port security feature. It enables a systemʼs

administrator to control who can connect to their network. You can use the

port security feature to restrict input to an interface by limiting and identifying

MAC addressed of the stations allowed to access the port. When you assign

secure MAC addresses to a secure port, the port does not forward with source

addresses outside the group of defined addresses. This decreases the possibility

that a non-authorized device can use our network for malicious purposes.

4.9.4.1 Port Configuration

The page is used to configure port security configuration.
First, you must select a port by clicking it from the following table. Then, begin to

set the port configuration. Please click when youʼre done with the modifications:

Admin: Enable or disable port security feature.
Violation Mode: It decides the port behavior when security violation

happens. If “Shutdown” is selected, the port becomes blocking state and

system logs a syslog message, and increments the violation counter. If

“Restrict” is selected, a syslog message is logged, and the violation counter

increments. If “Protect” is selected, you are not notified that a security

violation has occurred.
Max MAC Address: The maximum numbers of secure MAC addresses on

this port. It is between 1 and 132 and the total number in the system is 1024.
