- Classic Lock—Locks the port immediately, regardless of the number of addresses that have
already been learned.
- Limited Dynamic Lock—Locks the port by deleting the current dynamic MAC addresses
associated with the port. The port learns up to the maximum addresses allowed on the port. Both
re-learning and aging of MAC addresses are enabled.
- Secure Permanent—Keeps the current dynamic MAC addresses associated with the port and
learns up to the maximum number of addresses allowed on the port (set by Max No. of Addresses
Allowed). Relearning and aging are enabled.
- Secure Delete on Reset—Deletes the current dynamic MAC addresses associated with the port
after reset. New MAC addresses can be learned as Delete-On-Reset ones up to the maximum
addresses allowed on the port. Relearning and aging are disabled.
• Max No. of Addresses Allowed—Enter the maximum number of MAC addresses that can be learned
on the port if Limited Dynamic Lock learning mode is selected. The number 0 indicates that only static
addresses are supported on the interface.
• Action on Violation—Select an action to be applied to packets arriving on a locked port. The options
are:
- Discard—Discards packets from any unlearned source.
- Forward—Forwards packets from an unknown source without learning the MAC address.
- Shutdown—Discards packets from any unlearned source, and shuts down the port. The port
remains shut down until reactivated, or until the device is rebooted.
• Trap—Select to enable traps when a packet is received on a locked port. This is relevant for lock
violations. For Classic Lock, this is any new address received. For Limited Dynamic Lock, this is any
new address that exceeds the number of allowed addresses.
• Trap Frequency—Enter minimum time (in seconds) that elapses between traps.
STEP 4 Click Apply. Port security is modified, and the Running Configuration file is
updated.
