Configure Port Security Configure port security to limit the MAC addresses (MAC IDs) that can access a
given port. Port security is based on the number of MAC addresses supported
(none of which are statically defined). Static port security lets you specify
whether MAC addresses are auto-learned or manually defined.
To configure port security, from the Configure menu, choose Port Security.
Port security limits and identifies the MAC addresses of devices that can send
traffic through the switch port. The switch port does not forward traffic from
devices outside the defined group of devices. A security violation occurs when any
of the following conditions occur:
• A device, which has a MAC address different from any identified secure
MAC addresses, attempts to access the switch port.
• The number of MAC addresses on the port exceeds the maximum number
supported on the port.
