Syntax
To specify the destination and severity of messages logged:
log destination { console | nv-file | syslog ipAddress [ facility facilityId ] }
{ severity { severityValue | severityNumber } | off }
no log destination [ console | nv-file | syslog [ ipAddress ] ]
To specify which event categories are logged to syslog:
log destination syslog ipAddress { include | exclude } category [ category ]*
no log destination syslog ipAddress { include | exclude } [ category ]*
Release Information
Command introduced before JUNOSe Release 7.1.0.
Description
Configures the logging of system messages. You can direct messages to a destination,
limit the messages logged based on severity level, or limit the event categories for
which messages are logged. The
no versions restore default settings or reverse the
effect of previous commands that limited event categories.
NOTE: You can display traffic logs—such as ipTraffic, icmpTraffic, tcpTraffic, and
udpTraffic—only via the show log data command or from the SRP module console.
You cannot redirect traffic logs elsewhere, such as to a system log or nonvolatile
storage file, or to a Telnet session.
