Current send seq (Vs)
Send state variable (Ns value for the next I-frame to be
transferred).
Current Rcv seq (Vr)
Receive state variable (next in-sequence Ns to be accepted).
Last ACK’d sent frame (Va)
Acknowledged state variable (last valid Nr received).
No. of frames in ACK pend q
Number of transmitted I-frames waiting for acknowledgment.
No. of frames in transmit pend q
Number of frames waiting to be transmitted.
Local Busy
The local side of the LLC connection is sending RNRs.
Remote Busy
The remote side of the LLC is receiving RNRs.
Poll Retry count
Indicates the current value of the retry of the counter (counts down)
in the LLC protocol.
Appl output flow stopped
The LLC has told the application to stop giving it outgoing data
frames.
Send process running
This process runs concurrently with all other frame actions and
takes I-frames in the transmit queue and sends them.
Frames Xmt and Rcvd
Displays the total number of frame types transmitted (Xmt) and
(Rcvd).
I-frames discarded by LLC
Counter that displays the total number of I-frames discarded by the
LLC, usually because the sequence number is out of sequence.
I-frames refused by LLC user
Counter that displays the number of I-frames discarded by the
software above the LLC. For example, DLSw (Data Link Switching).
Set
Use the set command to dynamically configure the LLC parameters on a current
LLC session. Any changes that you make to the parameters are effective for the life
of session. These parameters are the same as those listed in “Set” on page237.
Attention: Changing LLC parameters from the default can affect how the LLC
protocol works.
