Route Switch Processor (RSP8) Installation and Configuration Guide

Configuring High System Availability
Note Standard 16-, 20-, or 32-MB Flash memory cards are supported with the RSP8. (The 20-MB Flash
memory card is currently the default.) See Flash Memory Card Installation Instructions for detailed
information.You should specify slot0 or slot1 in your command, depending on which slot you are using.
Standard 48-MB, 64-MB, and 128-MB Flash Disks are supported with the RSP8. See Using the Flash
Diskfor additional information. You should specify slot0 or slot1 in your command, depending on which
slot your are using.
The following example ensures that both RSPs have the same system image. Note that because no
environmentvariables are set, the default environment variables are in effect for both the active and the
standby RSP.

Current CONFIG_FILE variable =
BOOTLDR variable does not exist

Slave auto-sync config mode is on

Ensuring that Both RSPs Contain the Same Microcode Image
To ensure that both RSPs have the same microcode images, use the following commands beginning in
privileged EXEC configuration mode:
Command Purpose
Step1 Router#show controller cbus Determines the microcode images used on the
interface processors. If all interface processors are
running from the bundled system microcode, no
further action is required.
Step2 Router#dir {bootflash: | slot0: | slot1:} If any interface processors are running from the
Flash memory file system, verifies the location and
version of the activeRSP supplementary microcode.
