Breakout auto-configuration You can globally enable front-panel Ethernet ports to automatically detect SFP pluggable media in a QSFP+ or QSFP28 port. The port autoconfigures breakout interfaces for media type and speed. For example, if you plug a 40G DAC cable with 4x10G far-side transceivers into a QSFP28 port, the port autoconfigures in 10g-4x Interface-breakout mode. enable auto-breakout RJ-45 ports and ports that are members of a port group do not support breakout auto-configuration. The breakout auto-configuration feature is disabled by default.

By default: • An Ethernet interface is enabled (no shutdown) and assigned to the default VLAN. An Ethernet interface has no IP address and no L2 switchport is configured (no IP address). • A Fibre Channel interface is disabled (shutdown). Restrictions The default interface command removes all software settings and all L3, VLAN, VXLAN, 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 an Ethernet interface is configured 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 Interfaces 85
