Figure 2-12. The RLP Health Statistics Window
RLP Health statistics provide the following general usage information for all 
ports on the selected card:
Frames Received
The total number of frames received on all active serial 
ports on the selected RLP, expressed as a rate 
(frames/second).
Frames Transmitted
The total number of frames transmitted by all active 
serial ports on the selected RLP, expressed as a rate 
(frames/second).
Frames Rejected
The total number of frames rejected by all active serial 
ports on the selected RLP, expressed as a rate 
(frames/second). Each protocol handles rejected frames a 
little differently; in general, however, frames are rejected 
because the active protocol has detected an error in the 
frame itself.
Frames Retransmitted
The total number of frames retransmitted by all active 
serial ports on the selected RLP, expressed as a rate 
(frames/second). Frames are typically retransmitted to 
correct errors or if the receiving device was too busy to 
receive the original frames; a high retransmit rate can 
indicate a noisy transmission line. If this value is 
consistently above zero and there are no other problems, 
you may want to increase the value assigned to the 
Retransmission Timer in the port database record. (See 
your hardware documentation for more information.)
