Sys-Update using NetConf
This chapter contains examples of carrying out Sys-update using NetConf.
The system update feature provides the user with the option to upgrade or downgrade the OcNOS image in a router. A router's software can be upgraded when a new feature is introduced or when software bugs are fixed.
NetConf provides the user with the following options for sys-update:
1. Download the image and install.
2. To delete the downloaded image.
3. To cancel the image download which is in progress.
Download the Image and Install
On the Switch:
Connect to yangcli and proceed as shown below:
yangcli ocnos@127.1> sys-update-get url=http://10.12.40.120/jenkins-archives-3/onie/installer/OCNOS-1-3-6/EC_AS7326_56X/OCNOS_DC_IPBASE/OcNOS-1.3.6.241a-DC_IPBASE/EC_AS7326_56X-OcNOS-1.3.6.241a-DC_IPBASE-S0-P0-installer | Download the OcNOS image. After the command, wait for some time for the image to download. Same can be verified through CLI “show installers” (Refer to validation logs) |
yangcli ocnos@127.1> sys-update-install installerName=EC_AS7326_56X-OcNOS-1.3.6.241a-DC_IPBASE-S0-P0-installer | Install the downloaded image. |
Note: The sys-update-get CLI is updated with known-hosts-add parameter too support SCP and SFTP. Use the sys-update-get known-hosts-add=true CLI to download the OcNOS image file via SCP/SFTP.
When known-host-add parameter is given as true then the IP address/hostname is added into known_hosts file and proceed to sys-update.
If known-host-add parameter is not given and IP address/hostname is not present in the known_hosts file then sys-update-get via SCP/SFTP throws an error message
'%% Download failed, SSL peer certificate or SSH remote key was not OK'
