Troubleshooting the System
You can use log commands to discover and isolate problems with the system. For
information about using the log commands, see the JunosE System Event Logging
Reference Guide . Juniper Networks Customer Service can use core dump files to
troubleshoot line module and SRP module failures.
Creating Core Dump Files
You can enable the system to create a core dump file if a module fails. You can choose
to send the core dump file to an FTP server or save the file to NVS. Juniper Networks
Customer Service can then access the core dump file and analyze it to determine what
went wrong. Local core dumps—stored in NVS—are enabled by default. You can enable
the core dump from Boot mode or Global Configuration mode.
CAUTION: Create a core dump file only under the direction of Juniper Networks
Customer Service. Network function can be disrupted if you create a core
dump file while the system is running in a network.
On the E120 and E320 routers, the failure of some components on a line module generates
multiple core dumps to provide more complete information about system state at the
time of the failure. Other E Series routers generate only a single core dump for line module
failures. When you contact Juniper Networks Customer Service for assistance, send all
of the generated core dump files.
Boot Mode
To enable the core dump from Boot mode:
1.
Access Boot mode by reloading the SRP module; then press the mb key sequence
(case insensitive) during the countdown.
2.
Specify where the system should transfer the core dump file.
3.
Set the IP address and mask of the system interface over which you want to send the
core dump file.
4.
Specify the gateway through which the system sends the core dump file to the FTP
server.
