Route Switch Processor (RSP8) Installation and Configuration Guide

Configuring High System Availability
Automatic synchronization mode is on by default; however, to turn it on manually, use the following
commands beginning in privileged EXEC configuration mode:
The following example turns on automatic configuration file synchronization:
Router# configure terminal
Router(config)# slave auto-sync config
Router(config)# end
Router# copy system:running-config nvram:startup-config
Ensuring that Both RSPs Contain the Same System Image
For simple hardware backup, ensure that both RSP cards have the same system image.
To ensure that both RSPs have the same system image, use the following commands beginning in
privileged EXEC configuration mode:
Command Purpose
Step 1 Router# configure terminal Enters global configuration mode.
Step 2
Router(config)# slave auto-sync config Enables automatic synchronization mode.
Step 3
Router(config)# end Exits global configuration mode.
Step 4 Router# copy system: running-config nvram:startup-config Saves this information to your startup
configuration and copies the configuration to the
standby’s startup configuration.
Command Purpose
Step 1
Router# show bootvar Displays the contents of the BOOT environment variable
to learn the current booting parameters for the active and
the standby RSP.
Step 2 Router# dir {bootflash: | slot0: | slot1:}
or
Router# show {bootflash: | slot0: | slot1:}
Verifies the location and version of the active RSP
software image.
Step 3
Router#
dir {slavebootflash: | slaveslot0: |
slaveslot1:}
or
Router# show {slavebootflash: | slaveslot0: |
slaveslot1:}
Determines if the standby RSP contains the same
software image in the same location.
Step 4
Router#
copy {bootflash:[filename]|
slot0:[filename] |
slot1:[filename]}{slavebootflash:[filename] |
slaveslot0:[filename] | slaveslot1:[filename]}
Note
You might also have to use the delete and/or
squeeze command in conjunction with the
copy command to accomplish this step.
Copies the active’s system image to the appropriate
standby location. Use this command if the standby RSP
does not contain the same system image in the same
location.
Note
Deleted space is not reusable until after you
perform the squeeze command.
