Operation

Port Security:

Helps secure network by preventing unknown devices from forwarding packets

When link goes down, all dynamically locked addresses are ‘freed’

If a specific MAC address is to be set for a port, set the dynamic entries to 0, then only allow packets with a MAC address matching the MAC address in the static list

Dynamically locked MAC addresses are aged out if another packet with that address is not seen within the age-out time. The user can set the time-out value.

Dynamically locked MAC addresses are eligible to be learned by another port

Static MAC addresses are not eligible for aging

Dynamically locked addresses can be converted to statically locked addresses
