Cabletron Systems 2.2 PPP Link Statistics

Bridge Statistics 2-25

Bridging

¥Internal MACÑThe number of frames for which transmission fails due to an

internal MAC sublayer transmit error. This error is only counted in this

window if there have not been corresponding Late Collisions, Excessive

Collisions, or Carrier Sense Errors.

¥Transmit ErrorsÑThe total number of transmission errors of all types that

occurred while the selected interface was attempting to transmit frames.

Collision Errors

Indicates the collision errors that occurred during transmission from this

interface. Possible collision errors are:

¥SingleÑDisplays the number of transmitted frames on the selected interface

for which transmission was prevented by one collision.

¥MultipleÑDisplays the number of transmitted frames on the selected

interface for which transmission was prevented by more than one collision.

¥LateÑDisplays 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.

¥ExcessiveÑDisplays the number of transmitted frames on the selected

interface for which transmission was prevented by excessive collisions.

¥Collision ErrorsÑDisplays the total number of collision errors of all types that

occurred during transmission from this interface.

PPP Link Statistics

The PPP Link Status 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.

To access the PPP Link Statistics window from the Bridge Status window:

1. Click on the desired Port button ( ) to display the port menu.

2. Click on PPP Link Status. The PPP Link Statistics window, Figure 2-7, will

appear.

To access the PPP Link Statistics window from the Chassis View window:

1. Click on the appropriate port index to access the Port menu.

2. Click on PPP Link Status. The PPP Link Statistics window, Figure 2-7, will

appear.
