Table 3-30.	Port Statistics Screen Fields (continued)

Field		Description

Collisions		Indicates the total number of collisions detected on this port.
Single Collisions		Indicates the total number of packets that were transmitted successfully on this
		port after a single collision.
Multiple Collisions		Indicates the total number of packets that were transmitted successfully on this
		port after more than one collision.
Excessive Collisions		Indicates the total number of packets lost on this port due to excessive collisions.
Deferred Packets		Indicates the total number of frames that were delayed on the first transmission
		attempt, but never incurred a collision.
Late Collisions		Indicates the total number of packet collisions that occurred after a total length of
		time that exceeded 512 bit-times of packet transmission.

The following field values appear only when the port selected in the Unit/Port field is configured with a gigabit MDA.

Pause Frames	Transmitted column: Indicates the total number of pause frames transmitted on this
	port. Pause frames cause the transmitting port to temporarily suspend the
	transmission of packets when the receiving port’s frame buffer is full (gigabit ports
	only).
	Received column: Indicates the total number of pause frames received on this port.
	Pause frames cause the transmitting port to temporarily suspend the transmission
	of packets when the receiving port’s frame buffer is full (gigabit ports only).
