Managing the XSR
Performing Fault Management
When a software problem causes the XSR’s processor to fail, the system
captures pertinent data, produces a Fault Report, and restarts the router
automatically. The Fault Report is useful in diagnosing the problem. The
router can store one Fault Report, retaining the first Fault Report in case of
multiple failures. It is stored in a special RAM memory area which is
preserved if the XSR is rebooted but lost if the router is powered down.
When the XSR automatically reboots after a crash, the following sample
message is logged:
<186>May 29 22:20:59 1.1.1.1 PLATF System warm boot from crash
Fault Report Commands
The
show fault-report command displays the report. Refer to the XSR CLI
Reference Guide for more command details.
Using the Real-Time Clock
The XSR’s Real-Time Clock (RTC) is employed by other system software
modules to time-stamp events, alarms and is useful when no network clock
source is accessible. It is normally synchronized with a master clock source
over the network using the Simple Network Time Protocol (SNTP) but can
can also synchronize with the battery-supported RTC chip.
RTC/Network Clock Options
SNTP synchronizes the RTC with a network master clock but if there is no
network clock source the RTC clock is used on its own. The RTC maintains
the correct time with its battery even when the XSR is powered down.
RTC Commands
The real-time clock can be set with the
clock set command. The universal
time can be viewed with
show clock command. To set the SNTP server, use
the
sntp-client server command. Refer to the XSR CLI Reference Guide for
more command details.
