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.)
