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.

Port Configuration

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.

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