Displaying and Managing Crash Log EntriesUse the Crash Log Information Center window to display and manage crash log entries. You can delete (clear) all messages, delete one message at a time, and add messages (markers) to the crash log. Messages related to fatal errors are recorded in the crash error log. This information is stored in NVRAM and, therefore, remains after a restart or power outage. Crash Error Log information can be used as a diagnostic tool by your DIGITAL service representative, should you require assistance.

Managing Crash Log EntriesThe maximum number of crash log entries is 254. If this number is exceeded, the next message overwrites the oldest message starting at crash log entry number 1. You can insert informational messages, and delete entries, all at once or one at a time. Procedure:
Note: The crash log is cleared and the crash log entry number is reset to 1, if the total message record size is exceeded and a new message is logged. Because the length of each message is different, the speed with which the record becomes full varies, depending on the total number of characters of all messages logged. Determining When a Crash OccurredThe occurrence of a crash may not be obvious because the VNswitch module restarts automatically.You can use information from the crash error log to determine when a crash occurred. A time stamp is saved with each crash message if the time was set when the crash occurred. A time stamp tells you exactly when the crash occurred. See Setting and Viewing Clock Time for the CLI procedures to set the time. If a time stamp is not set, the uptime of the switch is saved. Procedure:
