Configure Security
This command is used to limits the number of active IP addresses on a port. The
Administrator can set the limit of the number of IP addresses that are allowed on
the port. The limit can range from 1 to 20.
The Administrator may configure a static IP address so that it is always part of
the table of authorized IP addresses. The number of learned addresses is
reduced by each static entry.
The IP addresses are the most recently learned addresses. For example, assume
that the administrator sets the limit to one, and the system has learned an IP
address. When a second DHCP acknowledge message is received, the first IP
address is deleted, and the new IP address is allowed.
