Guidelines and Restrictions
• The auto security command has no parameters.
•
Base line security CLIs (like port security) are not individually nvgen’d on interfaces that have auto
security-port configured. This allows you to maintain consistency over reboots.
• After auto security-port is enabled on a port, you cannot change the CLIs of the baseline security
features (Port Security, DAI, and DHCP Snooping).
For example, if you enter the following:
interface GigabitEthernet2/0/24
switchport mode access
auto security-port host
The port security configuration is rejected on the auto security port:
Switch(config)# int g2/0/24
Switch(config-if)# switchport port-security maximum 4
%Command Rejected: 'auto security' enabled port
•
Because you might need a different set of features on uplink ports, such as marking the port as a
DHCP trusted port, you need to identify uplink and downlink ports and apply port mode specific
configuration.
