cable sflog
cable sflog
To enable service flow logging and to configure the number and duration of entries in the log, use the
cable sflog command in global configuration mode. To disable service flow logging, use the no form of
the command.
Syntax Description max-entry number
entry-duration time
Defaults
max-entry = 0 (service flow logging is disabled) and entry-duration = 3600 seconds
Command Modes Global configuration
Command History Release
12.2(15)BC1
Usage Guidelines A DOCSIS specification currently being developed requires the DOCSIS CMTS to maintain a log table
that contains entries of deleted service flows. The cable sflog command enables the logging of deleted
service flows in this table and also sets the maximum number of entries in the log. When the log becomes
full, the oldest entries are deleted to make room for the newest ones.
This command also configures how long each entry can remain in the log. When an entry has been in the
table for the specified time, the CMTS deletes it, even if the log is not currently full.
To display the service flow log, use SNMP commands to display the docsQosServiceFlowLogEntry
entries in the docsQosServiceFlowLogTable table. These attributes are defined in the Data Over Cable
System Interface Specification Quality of Service Management Information Base (DOCSIS-QOS MIB)
internet draft.
Cisco IOS Release 12.2(15)BC1 supports version 4 of this DOCSIS-QOS MIB draft, which is available
on the IETF Internet-Drafts web site:

cable sflog max-entry number entry-duration time
no cable sflog
Specifies the maximum number of entries in the service flow log. When the
log becomes full, the oldest entries are deleted to make room for new entries.
The valid range is 0 to 59999, with a default of 0 (which disables service
flow logging).
Note
Specifies how long, in seconds, entries can remain in the service flow log.
The CMTS deletes entries in the log that are older than this value. The valid
range is 1 to 86400 seconds, with a default value of 3600 seconds (1 hour).
Modification
This command was introduced.
The max-entry value applies to the entire chassis on the
Cisco uBR7100 series and Cisco uBR7200 series routers, but applies
to individual cable line cards on the Cisco uBR10012 router.
