Defines
the
destination
IP
address
wildcard mask.

Security > Ports Security
Security > Ports Security
Network security can be increased by limiting access on
a specific port only to users with specific MAC addresses.
MAC addresses can be dynamically learned or statically
configured. Locked port security monitors both received
and learned packets that are received on specific ports.
Access to the locked port is limited to users with specific
MAC addresses. These addresses are either manually
defined on the port, or learned on that port up to the
point when it is locked. When a packet is received on a
locked port, and the packet source MAC address is not tied
