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
command.
