Answer
Procedure is different from ordinary IOS-XE software, but in most cases can be done via vManage controller in the same way as for vEdge routers and described in the following article: Software Installation and Upgrade for vEdge Routers
Although if CLI upgrade required, then this document should be helpful. In general this procedure is more like on vEdge routers, rather than on ordinary IOS-XE routers.
1. Download IOS-XE SD-WAN image for your device on https://software.cisco.com
2. Upload image to the device (e.g. with help of scp):
User-PC:Downloads User$ scp c1100-ucmk9.16.10.1.SPA.bin admin@10.48.87.244:/c1100-ucmk9.16.10.1.SPA.bin
Password:
c1100-ucmk9.16.10.1.SPA.bin 100% 407MB 488.7KB/s 14:12
Connection to 10.48.87.244 closed by remote host.
User-PC:Downloads User$
3. install new software:
Router#request platform software sdwan software install bootflash:c1100-ucmk9.16.10.1.SPA.bin
4. check that software was installed properly:
Router#show sdwan software
VERSION ACTIVE DEFAULT PREVIOUS CONFIRMED TIMESTAMP
--------------------------------------------------------------------------
16.10.1 false false false - 2019-01-16T13:22:47-00:00
16.9.3 true true true auto 2018-12-29T15:15:55-00:00
5. activate software:
Router#request platform software sdwan software activate 16.10.1
System will be reloaded automatically once completed.
6. Once device is reloaded, we can check that new version was activated:
Router#sh ver | i IOS.*Version
Cisco IOS XE Software, Version 16.10.1
Cisco IOS Software [], ISR Software (ARMV8EB_LINUX_IOSD-UCMK9-M), Version 16.10.1, RELEASE SOFTWARE (fc1)
Router#show sdwan software
VERSION ACTIVE DEFAULT PREVIOUS CONFIRMED TIMESTAMP
--------------------------------------------------------------------------
16.10.1 true false false auto 2019-01-16T13:56:38-00:00
16.9.3 false true true auto 2019-01-16T13:56:39-00:00
7. Optionally we can set new version as default:
Router#request platform software sdwan software set-default 16.10.1
Router#show sdwan software
VERSION ACTIVE DEFAULT PREVIOUS CONFIRMED TIMESTAMP
--------------------------------------------------------------------------
16.10.1 true true false auto 2019-01-16T13:56:38-00:00
16.9.3 false false true auto 2019-01-16T13:56:39-00:00
It will make sure that new version is preserved if software reset required (request platform software sdwan software reset)
8. Finally, don't forget to confirm the upgrade (request platform software sdwan software upgrade-confirm)
