Chapter 4 Software Upgrade Process
Upgrade Process With Service Impact for Nonredundant Platforms
Router# request platform software package install rp 0 file
bootflash:asr1000rp1-sip*02.02.01.122-33.XNB1*.pkg slot 2 force
Step 8 Install the ESPBASE package on the ESP:
Router# request platform software package install rp 0 file
bootflash:asr1000rp1-esp*02.02.01.122-33.XNB1*.pkg
Step 9 Copy the RPBase subpackage into the directory, then upgrade all of the RP subpackages simultaneously.
This step will upgrade the RPBase subpackage, which is the last remaining subpackage that requires an
upgrade:
request platform software package install rp 1 file
bootflash:asr1000rp*02.02.01.122-33.XNB1*.pkg force
Step 10 Enter show version provisioned to confirm that all of the software has been updated.
Step 11 Reload the router using the reload command when appropriate to complete the installation.
Downgrades in versions that do not support the {pattern} syntax are problematic because an
RPBASE package for the downgrade version will always be present if an upgrade was
previously performed. Removing and restaging all packages will work in this case, but they
effectively put the system into a state where if the RP reloads prior to the installation
being completed, the RP may no longer be bootable.
Upgrade Process With Service Impact for Nonredundant
Platforms
Subpackage software upgrade is supported for nonredundant platforms such as Cisco ASR 1001 Router,
Cisco ASR 1002, and ASR 1004 Routers in subpackage mode. This is because the software upgrade
procedure on these chassis types requires an RP reload when upgrading the RPBase subpackage at the
last step.
During the software upgrade process, there will be outage on the control plane as the entire platform is
rebooted so that access to the router operating system and ROMmon is lost for a period of time.
For non-hardware-redundant chassis types, SIP impact can be mitigated by installing SIPs one slot at a
time if SPAs are redundant across SIPs (such as when using Gigabit Etherchannel). ESP redundancy
provides similar capability for the ESP allowing hitless upgrade of a chassis from one software release
to another. Consolidated package mode does not provide such a per-slot staging option and always incurs
a traffic loss equivalent to simultaneous OIR of all SIPs.
For the Cisco ASR 1001 Router, the Cisco IOS Software redundancy requires 8-GB DRAM and the IOS
software redundancy license.
Note The Cisco ASR 1002 and ASR 1002-F Routers come by default with 4-GB DRAM. The Cisco ASR 1001
Router comes by default with 4-GB DRAM, and is upgradeable up to 8-GB or 16-GB DRAM.
