User Guidelines
This command returns an Ethernet, port channel, VLAN, tunnel or loopback
interface to the interface defaults as follows:
• Trunk and general mode configuration is removed.
• The interface is set to access mode using VLAN 1.
• The port is removed from all access-groups.
• The port is removed from port-channels.
• Speed/duplex are set to defaults.
• Spanning tree is enabled.
• Loop protection, BFD, and UDLD are disabled.
• Port MAC locking is disabled.
• Static MAC address entries referencing the interface are removed.
• Private VLAN configuration is removed.
Use of this command may cause the interface to drop the link. This is
particularly true when the port defaults to a 10G fiber port and the installed
transceiver requires auto-negotiation to be enabled.
