Table 8-16. debug Commands for ISDN
Note Debug functions are processor intensive. The debug isdn commands in par-
ticular display a high volume of messages to the CLI.
Some of the debug isdn commands display numerous messages, which are
displayed too quickly to read. You will probably need to stop the messages
and review them to determine the problem. For example, Figure 8-26 shows
a small portion of the debug messages displayed as a call connects.
