Cisco Cisco IOS XR Software Release 3.2

Use the following procedure to upgrade the Cisco IOS XR software from Release 3.2.1 to Release 3.2.2 
on a Cisco CRS-1:

Enter the admin EXEC mode:

RP/0/RP0/CPU0:router# admin
RP/0/RP0/CPU0:router(admin)#

Add the required PIE files to disk:

RP/0/RP0/CPU0:router(admin)# install add <device or tftp/ftp/rcp>/PIE_filename to disk0: 
sync

Step 1 must be repeated for each of the PIE files listed in 

 or all of the PIE 

files can be added together in a single install add command. To add all PIE files using a single command, 
list all of the PIE files (including their source) within the install add command in the following manner:

RP/0/RP0/CPU0:router(admin)# install add <device or tftp/ftp/rcp>/comp-hfr-mini.pie-3.2.2 
<device or tftp/ftp/rcp>/hfr-mcast-p.pie-3.2.2 <device or 
tftp/ftp/rcp>/hfr-mgbl-p.pie-3.2.2 <device or tftp/ftp/rcp>/hfr-mpls-p.pie-3.2.2 <device or 
tftp/ftp/rcp>/hfr-k9sec-p.pie-3.2.2 to disk0: sync

The use of sync option prevents the user from issuing any other command while the installation is in 
process.

Activate all of the added packages together:

RP/0/RP0/CPU0:router(admin)# install activate disk0:comp-hfr-mini-3.2.2 
disk0:hfr-mcast-3.2.2 disk0:hfr-mgbl-3.2.2 disk0:hfr-k9sec-3.2.2 disk0:hfr-mpls-3.2.2 sync

The output of install add command issued in Step 2 provides the list of names of packages to be used 
in install activate command.

The use of sync option prevents the user from issuing any other command while the installation is in 
process.

As this is an impactful upgrade, the router reloads at the end of activation to start using the new 
packages.

Do not activate any other packages during the upgrade. Additional packages can be activated after 
upgrade has completed.
