Security > Port Security
The Port Security screen is used to configure a port's
security settings.
Security > Port 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's source MAC address is not tied to that port (either
it was learned on a different port, or it is unknown to the
system), the protection mechanism is invoked, and can
provide various options. Unauthorized packets arriving at
a locked port are either:
Forwarded
•
Discarded
•
Cause the port to be shut down
•
Locked port security also enables storing a list of MAC
addresses in the configuration file. The MAC address list
can be restored after the device has been reset.
