Cisco 7500 SERIES ROUTE SWITCH PROCESSOR 16 Specification Guide

To access the state of the failed RSP in the form of a stack trace from the active console, use the
following command in privileged EXEC configuration mode:

For information about other commands that you can use to display information about the RSPs, see the

This section includes the following RSP16 maintenance procedures:

This section describes the procedures for saving and retrieving a system configuration file using a Trivial
File Transfer Protocol (TFTP) server.

Configuration information resides in two places when the router is operating: the startup default
(permanent) configuration in NVRAM, and the running (temporary) memory in RAM. The default
startup configuration always remains available; NVRAM retains the information even when the power
is shut down. The current information is lost if the system power is shut down. The current configuration
contains all nondefault configuration information that you added with the configure command, the setup
facility, or editing of the configuration file.

The configure command adds the current configuration to the default configuration in NVRAM so that
it is also saved when power is shut down. Whenever you make changes to the system configuration, enter
the copy running-config startup-config command to ensure that the new configuration is saved.

If you replace the RSP16 in a system with only one RSP16, you also replace the entire configuration,
which resides in NVRAM on the RSP16. If you copy the configuration file to a remote server before
removing the RSP16, you can retrieve it later and write it into NVRAM on the new RSP16. You can also
use the copy running-config slot0:config-file command to save the configuration file to Flash memory,
and then use the copy slot0:config-file nvram:startup-config command to restore it.

If you do not copy the configuration file, you must use the configure command or the setup facility to
re-enter the configuration information after you install the new RSP16. For complete descriptions of
these two commands, and instructions for using them, refer to the appropriate software documentation.
