To interpret this data:
• 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 guide.
• 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.
• The Persistence Flag gives a message priority over others that do not have the flag set.
