Configuring Port Security
◆
When the port security state is changed from enabled to disabled, all
dynamically learned entries are cleared from the address table.
◆
If port security is enabled, and the maximum number of allowed addresses are
set to a non-zero value, any device not in the address table that attempts to use
the port will be prevented from accessing the switch.
◆
If a port is disabled (shut down) due to a security violation, it must be manually
re-enabled from the Interface > Port > General page
◆
A secure port has the following restrictions:
It cannot be used as a member of a static or dynamic trunk.
■
It should not be connected to a network interconnection device.
■
RSPAN and port security are mutually exclusive functions. If port security is
■
enabled on a port, that port cannot be set as an RSPAN uplink port, source
port, or destination port. Also, when a port is configured as an RSPAN
uplink port, source port, or destination port, port security cannot be
enabled on that port.

The maximum address count is effective when port security is enabled or
disabled.
