Serial (USI) Statistics Report
Type S to display the Serial Statistics report. This report displays basic
serial (HDLC) transport statistics on the Universal Serial Interlace port.
BECN set on Tx Backward Explicit Congestion Notification status
set to notify DTE that congestion avoidance should
be initiated by the sending device.
Tx congestion counter No. of frames dropped due to congestion to
maintain committed information rate.
CLLM frames Tx No. of CLLM frames received
LMI frames Tx No. of LMI frames received
ANSI frames Tx No. of ANSI frames received
Last error: Description of last recorded error since reset.
Table 12–19.Serial Statistics Report
Parameter Description
bytes rcvd Total data received in bytes.
packets rcvd No. of Serial packets received.
discarded, RX Busy No. of discarded received packets due to packets
Overrun.
Available Buffers (PCB
Entries)
Current available internal PCB (Packets Buffers)
entries.
discarded, RX error: No. of discarded due to the following reasons:-
Could not allocate packet buffers.
Rx Clock glitch Total frames discarded on this port due to receives
clock glitch errors.
PLL error Total frames discarded on this port due to receives
phase lock loop errors.
Frame too long Total frames discarded on this port because the
received frame was too long.
Non octet aligned Total frames discarded on this port because the
received frame was not an integral no. of octets.
Abort seq No. of frames aborted on the port due to receiving
an abort sequence since system re-initialization
and the port state was ‘up' or 'test'.
CRC error Total frames discarded on this port due to received
CRC errors.
Rx overrun Total frames discarded on this port due to receiver
overruns errors.
CD lost Total frames discarded on this port due to lost
Carrier Detect.
Out Of Buffers (PCBs) No. of times that could not allocate a packet buffer
for received packets.
