Collision Errors

Single

Displays the number of successfully transmitted frames on the selected interface for which transmission was prevented by one collision.

Multiple

Displays the number of successfully transmitted frames on the selected interface for which transmission was prevented by more than one collision.

Late

Displays the number of times that a collision has been detected on this interface later than 51.2 microseconds into the transmission of the packet on a 10 Mbit/s system or later than 5.12 microseconds on a 100 Mbit/s system.

Excessive

Displays the number of frames from this interface for which transmission was not complete due to excessive collisions.

Collision Errors

Displays the total number of collision errors of all types that occurred during transmission from this interface.

The PPP Link Statistics Window

The PPP Link Status menu option opens the PPP Link Statistics window, which enables you to view color-coded statistics related to the PPP (Point-to-Point Protocol) link at the selected interface.

The Point-to-Point Protocol is a standard method of transporting multiprotocol datagrams over point-to-point links. A PPP Link provides full-duplex communication between the endpoints, allowing a simultaneous bidirectional operation that should maintain the order in which data packets are transmitted.
