Logging Enterprise-Specific Traps

Problem

You want to collect Juniper Networks enterprise-specific traps in the router's system logging files.

Solution

Use the following commands to save all log messages to a file called snmp-critical-traps:

	[edit]
	user@router1# edit system syslog file snmp-critical-traps 
	[edit system syslog file snmp-critical-traps ]
	user@router1# set daemon critical 

 

Discussion

The traps from the Juniper Networks chassis MIB all have a system logging severity level associated with them. You can take advantage of this to collect these traps in a system logfile. The chassis traps record chassis component information that is critical to the operation of the router, such as power supply and fan failures. In this recipe, we collect all critical and alert logging messages generated by all JUNOS processes, including SNMPD and MIB2D, which captures most of the SNMP chassis traps.

Table 4-2 shows all the chassis traps and their corresponding severity level. In the system logging file, these messages are prefixed with the identifier CHASSISD_SNMP_TRAP.

The Juniper Networks chassis MIB traps are the only enterprise-specific traps that are associated with a system logging severity level, so they are the only ones that you can specifically log.
