Port Security Commands

42-2

42

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.

• First use the port security max-mac-count command to set the number of

addresses, and then use the port security command to enable security on
the port.

• Use the no port security max-mac-count command to disable port security

and reset the maximum number of addresses to the default.

• 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:
