Typically, equal numbers of SABM and UA are expected. Significant numbers
of "Abort, Bad Type, Bad CRC, RNR or Rejects" indicates a fundamental
problem in the hardware, its configuration, or the link to the other site.

The above displays the current configuration and operating status of the
X.25 stack at the HDLC [lowest] layer. Note that "Trace" is "Off".
Typically, tracing down at the HDLC layer is only performed when
troubleshooting X.25 connection [link] problems.

This command reports many of the critical X.25 layer configuration
parameters. Generally, Window size, Packet size, Packet format should match
the other party's X.25 configuration to maximize throughput and
performance. Note that "Trace" is currently "Off". Tracing at the X.25 is
useful when troubleshooting X.25 connectivity issues and sometimes even
application issues (for applications that are run across the link).
