Event and Accounting Logs
7950 SR OS System Management Guide Page 373
When initialized, each file will contain:
• The log-id description.
• The time the file was opened.
• The reason the file was created.
• If the event log file was closed properly, the sequence number of the last event stored on the log
is recorded.
If the process of writing to a log file fails (for example, the compact flash card is full) and if a backup
location is not specified or fails, the log file will not become operational even if the compact flash
card is replaced. Enter either a
clear log command or a shutdown/no shutdown command to
reinitialize the file.
If the primary location fails (for example, the compact flash card fills up during the write process), a
trap is sent and logging continues to the specified backup location. This can result in truncated files in
different locations.
The no form of the command removes the file-id from the configuration. A file-id can only be
removed from the configuration if the file is not the designated output for a log destination. The actual
file remains on the file system.
Default No default file IDs are defined.
Parameters file-id — The file identification number for the file, expressed as a decimal integer.
Values 1 — 99

Description This command specifies the primary location where the log or billing file will be created.
The location command is optional. If the location command not explicitly configured, log files will
be created on cf1: and accounting files will be created on cf2: without overflow onto other devices.
Generally, cf3: is reserved for system files (configurations, images, etc.).
When multiple location commands are entered in a single file ID context, the last command
overwrites the previous command.
When the location of a file ID that is associated with an active log ID is changed, the log events are
not immediately written to the new location. The new location does not take affect until the log is
rolled over either because the rollover period has expired or a
clear log log-id command is entered to
manually rollover the log file.
When creating files, the primary location is used as long as there is available space. If no space is
available, an attempt is made to delete unnecessary files that are past their retention date.
If sufficient space is not available an attempt is made to remove the oldest to newest closed log or
accounting files. After each file is deleted, the system attempts to create the new file.
