Information About OBFL

Message Logging

The OBFL feature logs standard system messages. Instead of displaying the message to a terminal, the
message is written to and stored in a file, so the message can be accessed and read at a later time. System
messages range from level 1 alerts to level 7 debug messages, and these levels can be specified in the
hw module logging onboard command.

A timestamp shows the date and time the message was logged.
Facility-Sev-Name is a coded naming scheme for a system message, as follows:
– The Facility code consists of two or more uppercase letters that indicate the hardware device
(facility) to which the message refers.
– Sev is a single-digit code from 1 to 7 that reflects the severity of the message.
– Name is one or two code names separated by a hyphen that describe the part of the system from
where the message is coming.
The error message follows the Facility-Sev-Name codes. For more information about system
messages, see the Cisco IOS System and Error Messages
Count indicates the number of instances of this message that is allowed in the history file. Once that
number of instances has been recorded, the oldest instance will be removed from the history file to
make room for new ones.
