Sample Output
For an M20 router:
user@host> show log messages Jun 3 16:43:19 flitter ssb CM(0): ALARM SET: (Major) fxp0: ethernet link down Jun 3 16:43:19 flitter craftd[582]: forwarding display request to chassisd: type = 4, subtype = 43 Jun 3 16:43:19 flitter alarmd[581]: Alarm set: fxp0 color=RED, class=ETHER, reason=fxp0: ethernet link down Jun 3 16:43:19 flitter mib2d[586]: SNMP_TRAP_LINK_DOWN: ifIndex 1, ifAdminStatus up(1), ifOperStatus down(2), ifName fxp0 Jun 3 16:43:21 flitter /kernel: fxp0: media DOWN 100Mb / full-duplex
For M40e and M160 routers:
user@host> show log messages Jun 7 18:18:50 myrouter craftd[2654]: Minor alarm set, Front Top Fan Absent Jun 7 18:18:50 myrouter chassisd[2652]: CHASSISD_BLOWERS_SPEED: blowers being set to full speed [fan/blower missing] Jun 7 18:18:50 myrouter alarmd[2653]: Alarm set: Fan color=YELLOW, class=CHASSIS, reason=Front Top Fan Absent Jun 7 18:18:50 myrouter craftd[2654]: fpm led error: Unknown error: -1 Jun 7 18:18:50 myrouter alarmd[2653]: Alarm set: Craft IF color=YELLOW, class=CHASSIS, reason=Craft Failure Jun 7 18:18:50 myrouter craftd[2654]: Minor alarm set, Craft Failure
Meaning
The messages system log file records the time the failure or event occurred, the severity level, a code, and a message description. Use the show log messages command to browse error messages that are generated at least 5 minutes before and after an event. Use this information to diagnose a problem and to let the Juniper Networks Technical Assistance Center (JTAC) know what error messages were generated and the router events prior to the event.
For an M20 router, the messages file output shows that the Ethernet management interface (fpx0) that provides an out-of-band method for connecting to the router from the craft interface is down. For more information about system log messages, see the Junos OS System Log Messages Reference.
For an M160 router, since the craft interface is attached to the front top fan, you see both craft interface and fan error messages.
