Port Security
NOTE
Port security cannot be enabled on ports on which 802.1X is enabled..
Network security can be increased by limiting access on a port to users with
specific MAC addresses. The MAC addresses can be either dynamically learned
or statically configured.
Port security monitors received and learned packets. Access to locked ports is
limited to users with specific MAC addresses.
