1. Introduction
1.1 Purpose, Audience and Scope
The purpose of this document is to describe the upgrade and downgrade procedure for the Cisco ASR 9000 Series
Aggregation Services Router, Release 4.3.4.
Audience: This guide is for Cisco Systems Field Engineers and Network Operators.
1.2 Important Notes
1. From R4.3.0 onwards, a single combo image is introduced to support x86 (-px- image) and ppc (-p- image)
hardware architectures. The combo image will still be called asr9k-mini-px.vm. The optional pies - mpls,
mcast, mgbl, FPD, etc. and SMUs will have the -px- suffix.
2. Turboboot with format is needed to downgrade from 4.3.4-px to any pre-4.3.0 images (Refer to Section 9).
3. FPD pie is not included in the combo image, it must be installed separately to complete manual firmware
upgrade. Users upgrading from –p- to R4.3.4 –px- image must add fpd pie explicitly to complete the manual
firmware upgrade.
4. Lawful Intercept (LI) pie is needed to activate any LI functionality.
5. BNG pie is needed to activate any BNG functionality.
6. Services pie is needed to activate any CGN functionality.
7. The CGv6 install kit of the 4.3.4 release must be downloaded onto the ISM Line Card prior to upgrading the
XR image. Add the following steps if required :
Copy the install kit to disk0:
In admin mode, download CGv6 install-image ((admin) #download install-image disk0: install kit) to ISM
location Verify the card comes up and shows "APP-READY"
Also verify "show platform summary location ISM location". The application in this output should show 4.3.4
application
8. In R4.3.1 (or later) ASR-903 satellite is not supported on RSP2. Hence, asr9k-asr903-nV-px.pie should not be
installed on a RSP2 system.
1.3 Summary of Upgrade Steps
1. Download the correct image tarball from http://www.cisco.com to a tftpserver. The image tarball on
http://www.cisco.com cannot be used as-is. The CCO image tarball for Release 4.3.4 must be downloaded to
a tftpserver and only relevant packages or SMUs must be taken and tarred into another tarball for use on the
router.
2. Install add/activate all the mandatory SMUs required to be active in the current release before upgrading to
Release 4.3.4. Refer to the Section "Mandatory SMUs (Upgrade and Downgrade)" for a list of SMUs to be
used. The mandatory SMUs are available in the downloaded tar file.
