The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

To configure all Layer 2 switchports to be Layer 3 routed ports, use the system default switchport shutdown command. To reset to the default of all Layer 2 swithports, use the no form of this command.
system default switchport shutdown
no system default switchport shutdown
This command has no arguments or keywords.
The default is all ports configured as Layer 2 switchports.

When the system default switchport shutdown command is issued, any switchports (including FEX HIFs) that are not configured with no shutdown command are shut down. To avoid the shutdown, configure the switchports with no shutdown command.
This example shows how to set all ports as Layer 3 routed ports:
switch# configure terminal switch(config)# system default switchport shutdown switch(config)#
This example shows how to reset all ports back to Layer 2 switchports:
switch# configure terminal switch(config)# system default switchport shutdown switch(config)#
