Chapter 2 Cisco CMTS Configuration Commands
cable event syslog-server
To enabling logging of DOCSIS event messages to a SYSLOG server, use the cable event syslog-server
command in global configuration mode. To disable the logging of a DOCSIS syslog server, use the no
form of this command.
Syntax Description ip-address
Defaults 0.0.0.0 (no DOCSIS SYSLOG server is defined)
Command Modes Global configuration
Command History Release
12.2(8)BC1
Usage Guidelines
The DOCSIS 1.1 specifications require the CMTS to generate a set of messages for DOCSIS-specific
events. Use the cable event syslog-server command to enable DOCSIS SYSLOG services and to set the
IP address for the DOCSIS SYSLOG server (which is the docsDevEvSyslog attribute in the
CABLE-DEVICE-MIB
You can also configure the server's IP address by using SNMP commands to set the docsDevEvSyslog
attribute directly. Setting the docsDevEvSyslog attribute also creates a matching cable event syslog-
server command in the router's configuration.
When you specify the IP address for a DOCSIS SYSLOG server, either by using the cable event syslog-
server command or by setting the docsDevEvSyslog attribute, the Cisco CMTS begins generating event
messages that conform to the DOCSIS 1.1 specifications. This format is similar to but not identical to
the format that is used by the Cisco IOS software. For example, the following message is in the typical
Cisco IOS format:
%UBR7200-4-DCC_ACK_REJ_MSG_SYNTAX_ERROR: DCC-ACK rejected message syntax error
The same error message appears as follows when using the DOCSIS 1.1 format:
<133>CMTS[DOCSIS]:<67040500> DCC-ACK rejected message syntax error
To disable the sending of events to the DOCSIS SYSLOG server, you can use the no cable event syslog-
server command, or you can specify an IP address of 0.0.0.0 (cable event syslog-server 0.0.0.0). Both
commands set the docsDevEvSyslog attribute to 0.0.0.0 and disable DOCSIS SYSLOG service. This
does not, however, disable the Cisco IOS SYSLOG server (if one has been configured using the logging
ip-address command).
