Bridging

¥

ÑThe 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.

¥

ÑThe total number of transmission errors of all types that 

occurred while the selected interface was attempting to transmit frames.

Indicates the collision errors that occurred during transmission from this 
interface. Possible collision errors are:

¥

ÑDisplays the number of transmitted frames on the selected interface 

for which transmission was prevented by one collision.

¥

ÑDisplays the number of transmitted frames on the selected 

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

¥

ÑDisplays 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.

¥

ÑDisplays the number of transmitted frames on the selected 

interface for which transmission was prevented by excessive collisions.

¥

ÑDisplays the total number of collision errors of all types that 

occurred during transmission from this interface.

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, 

, 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.
