Table 18: Operational Mode Commands for Router Monitoring (continued)
DescriptionCommand
Displays more detailed operational status information
about the following components:
•
M7i router: CFEB, FPC, PIC, and Routing Engine
•
M10i router: CFEB, Ethernet switch, FPC, PIC, and
Routing Engine
•
M20 router: FPC, PIC, Routing Engine, and SSB
•
M40e/M160 router: Ethernet switch, FPCs, PICs,
Routing Engine, and SFMs
•
M120 router: Alarms, Craft interface, Environment,
Ethernet switch, fabric, fan, FEB, firmware, FPC,
hardware, PICs, and Routing Engine
•
M320 router: Ethernet switch, FPCs, SIBs, PICs, and
Routing Engine
•
T320, T640, T1600, TX Matrix, and TX Matrix Plus
routers: Ethernet switch, FPCs, PICs, Routing Engine,
SIBs, and switch processor mezzanine board (SPMB)
The command displays the total CPU DRAM and SRAM
being used by the SFM processor. The command output
displays the time that the SFM became active and how
long the SFM has been up and running. A small uptime
means that the component came online a short time ago
and could indicate a possible FPC error condition.
show chassis component-name
Displays the contents of the messages system log file
that records messages generated by component
operational events, including error messages generated
by component failures.
To monitor the messages file in real time, use the monitor
start messages command. This command displays the
new entries in the file until you stop monitoring by using
the monitor stop messages command.
show log messages
Displays the contents of the chassis daemon (chassisd)
log file that keeps track of the state of each chassis
component
To monitor the chassisd file in real time, use the monitor
start chassisd command. This command displays the
new entries in the file until you stop monitoring by using
the monitor stop chassisd command.
show log chassisd
