Configuring Port Security
– 341 –
◆
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. Also,
when a port is configured as an RSPAN uplink port, source port, or
destination port, port security cannot be enabled on that port.
