Reset default configuration
You can clear all configured settings on an Ethernet or Fibre Channel interface and reset the interface to its default settings. By
default:
An Ethernet interface is enabled, using the no shutdown command, and assigned to the default VLAN.
A Fibre Channel interface is disabled, using theshutdown command.
Restrictions
The default interface command removes all software settings and all L3, VLAN, and port-channel configurations on a
port interface. However, the command does not remove configurations to the interface from other software features, such as
VLT. If you do not remove these configured settings, the command does not execute. For example, if you configure an Ethernet
interface as a discovery interface in a VLT domain and you do not delete this setting, resetting the interface to its default
configuration fails:
OS10(config)# vlt-domain 10
OS10(conf-vlt-10)# discovery-interface ethernet 1/1/1
OS10(conf-vlt-10)# exit
OS10(config)# default interface ethernet 1/1/1
Proceed to cleanup the interface config? [confirm yes/no]:y
% Error: Discovery Interface mode must not be in switchport mode
