Route Switch Processor (RSP8) Installation and Configuration Guide
OL-4920-02
Configuring High System Availability
Upgrading to a New Software Version Example
Note The following examples show systems with two RSP8s.
The following example describes an upgrade scenario under the following conditions:
The activeRSP8 is in processor slot 6, and the standby RSP8 is in processor slot 7 of a Cisco 7513
or Cisco 7513-MX.
Both the active and the standby RSPs currently use the same Cisco IOS Enterprise image,
rsp-pv-mz.120-23.S, in PC Card slot 0.
We want to upgrade one RSP to run Cisco IOS Release 12.0(22.3)S1, and allow the other RSP to
run Cisco IOS Release 12.0(23)S. To guard against software failures, we will configure HSA
operation for software error protection.
Step5 Router(config)#boot system flash bootflash:[filename]
or
Router(config)#boot system flash slot0:[filename]
or
Router(config)#boot system flash slot1:[filename]
Configures the active RSP to boot the new image from
the appropriate location.
Note In this procedure, the image that you specify in
thiscommand only resides on the first, or active,
RSP.
Step6 Router(config)#boot system flash bootflash:[filename]
or
Router(config)#boot system flash slot0:[filename]
or
Router(config)#boot system flash slot1:[filename]
Configures a secondboot system command that
specifies the boot image and location on the standby
RSP.
Note This is the boot image that the standby uses
when it boots the system as the active RSP,
assumingthat the image file that you specified in
thefirst boot system command does not exist on
the second RSP. Therefore, when the standby
RSP cannot locate the image in the firstboot
systemcommand, it uses the image specified in
this second command.
Step7 Router(config)#boot system {rcp |tftp | ftp}filename
[ip-address](Optional) Configures the active RSP to boot from a
network server.
Step8 Router(config)#config-register value 1Sets the configuration register to enable loading of the
system image from a network server or Flash memory.
Step9 Router(config)#end Exits global configuration mode and returns you to
privileged EXEC configuration mode.
Step10 Router#copy running-config nvram:startup-config Saves the configuration file to the active RSP startup
configuration. Because automatic synchronization is
turnedon, this step saves the boot system commands to
the active and the standby startup configuration.
Step11 Router#reload Resets the router with the new configuration
information.

configuration register.
