ISDN Debug and Show Commands
debug isdn
This command initiates a Layer 2 or 3 ISDN debug session to trace failed calls at the D channel
level. Issuing the command has the effect of locking out debugging by any other Telnet or Console
connection. If both Layer 2 (Q921) and 3 (Q931) choices are selected, tracing will display both
layers.
You can exit the debug session either by isuing the no debug isdn command or terminating the
Telnet or Console session.
Optionally, you can set a limit of up to 9999 messages which will display at the CLI after which the
debug session will end. If the limit is not specified, after 100 displayed messages, the
no debug
isdn command will automatically be run. The limit parameter is a global value that is refreshed
each time debug isdn is entered.
