Information About Interface Characteristics
Before a switch can relay frames from one data link to another, you must define the characteristics of the interfaces through which the frames are received and sent. The configured interfaces can be Ethernet (physical) interfaces, virtual Ethernet interfaces, and the management interface.
Each interface has the following:
Administrative Configuration—The administrative configuration does not change unless you modify it. This configuration has attributes that you can configure in administrative mode.
Operational State—The operational state of a specified attribute, such as the interface speed. This state cannot be changed and is read-only. Some values might not be valid when the interface is down (such as the operation speed).
For detailed information about port modes, administrative states, and operational states, see the Cisco Nexus 1000V Interface Configuration Guide.
