Command Usage
• If you enable 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 will be accepted.
• Use the
port security
command to enable security on a port. Then use the
port security
action
command to set the response to a port security violation,
and the
port security max-mac-count
command to set the maximum
number of addresses allowed on a port.
• You can also manually add secure addresses with the
mac-address-table
static
command.
• A secure port has the following restrictions:
- Cannot be connected to a network interconnection device.
- Cannot be a trunk port.
• If a port is disabled due to a security violation, it must be manually re-enabled
using the
no
shutdown
command.
Example
The following example enables port security for port 5, and sets the response to a
security violation to issue a trap message:
