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 log messages 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 CLI command. This command
displays the new entries in the file until you stop
monitoring by using the
monitor stop messages CLI
command.
