# Port Security

You can use the port security feature to restrict input to an interface by limiting and identifying MAC addresses of the workstations that are allowed to access the port. When you assign secure MAC addresses to a secure port, the port does not forward packets with source addresses outside the group of defined addresses. If you limit the number of secure MAC addresses to one and assign a single secure MAC address, the workstation attached to that port is assured the full bandwidth of the port.

This dialog box allows you to configure and view the global Port Security features. To configure Port Security features on a specific interface, see Port Security Configuration.

Total Secure MAC Addresses (cpsGlobalTotalSecureAddress)

Total number of MAC addresses secured by the device.

Port Security Status (cpsGlobalPortSecurityEnable)

Global control to enable or disable port security feature on the device.

SNMP Notification Rate (cpsGlobalSNMPNotifRate)

Global control to set the SNMP notification rate for the port security feature. This object specifies the rate at which SNMP notifications are generated when the cpsIfViolationAction selected is of the type "dropNotify". A value of 0 indicates that an SNMP notification is generated for every security violation.
