Excessive Collisions

The number of frames for which transmission on this interface failed due to excessive collisions.

MAC Errors: Transmit

The number of frames for which transmission on this interface failed due to an internal MAC sublayer transmit error. This number does not include Carrier Sense Errors, Late Collisions, or Excessive Collisions.

MAC Errors: Receive

The number of frames for which reception on this interface failed due to an internal MAC sublayer receive error. This number does not include Alignment Errors, FCS Errors, or Frame Too Long Errors.

Speed (Mbps)

The nominal bandwidth of the interface in megabits per second.

Duplex

The current LAN duplex transmission mode for this interface:

•Full = Full-Duplex: transmission in both directions at the same time.

•Half = Half-Duplex: transmission in only one direction at a time.
