ECURITY
These commands can be used to enable port security on a port.
When using port security, the switch stops learning new MAC addresses on
the specified port when it has reached a configured maximum number.
Only incoming traffic with source addresses already stored in the dynamic
or static address table for this port will be authorized to access the
network. The port will drop any incoming frames with a source MAC
address that is unknown or has been previously learned from another port.
If a device with an unauthorized MAC address attempts to use the switch
port, the intrusion will be detected and the switch can automatically take
action by disabling the port and sending a trap message.
port security
This command enables or configures port security. Use the
no
form without
any keywords to disable port security. Use the
no
form with the
appropriate keyword to restore the default settings for a response to
security violation or for the maximum number of allowed addresses.
