History
Usage
The debug level produces a lot of messages, and many can appear to be cryptic. Debug
messages are used primarily by Trapeze Networks for troubleshooting and are not intended for
administrator use.
Examples Type the following command to see the facilities that you can view event messages
archived in the buffer:
buffer Displays the log messages in nonvolatile storage.
+|-number-of-messages Displays the number of messages specified as follows:
❑ A positive number (for example, +100), displays that number of log entries
starting from the oldest in the log.
❑ A negative number (for example, -100) displays that number of log entries
starting from newest in the log.
facility facility-name Area of MSS that is sending the log message. Type a space and a question
mark (?) after show log buffer facility for a list of valid facilities.
matching string Displays messages that match a string—for example, a username or IP
address.
severity severity-level Displays messages at a severity level greater than or equal to the level
specified. Specify one of the following:
❑ emergency—The MX is unusable.
❑ alert—Action must be taken immediately.
❑ critical—You must resolve the critical conditions. If the conditions are not
resolved, the MX can reboot or shut down.
❑ error—The MX is missing data or is unable to form a connection.
❑ warning—A possible problem exists.
❑ notice—Events that potentially can cause system problems have occurred.
These are logged for diagnostic purposes. No action is required.
❑ info—Informational messages only. No problem exists.
❑ debug—Output from debugging.
