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 Step 11 Enter show version provisioned to confirm that all of the software has been updated. 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.
