Displaying and Managing Boot Environment (BE) Information

Netvisor ONE provides two boot environments (BEs): the current boot environment, and the previous boot environment. The presence of two BEs enable you to rollback or rollforward the software versions or configurations.

During software upgrade, a new boot environment is automatically created to install the new software and after the software upgrade, the switch boots into the newly created BE that is  running the new software. Also, during software upgrade the older BE (which was not active) is deleted, and the current BE from where software upgrade started is preserved, and then the switch boots into newer BE with new software. This process ensures that there are only two boot environments (BEs) after upgrade.

To display boot environment information, use the following command:

CLI (network-admin@switch) > bootenv-show

name       version     current reboot space created        apply-current-config

--------- ----------- ------- ------ ----- -------------- --------------------

netvisor-1 5.2.1-15718  no      no     0    02-23,04:22:46      false                

netvisor-2 6.1.0-17888  yes     yes    0    03-06,20:47:13      false                

To reboot the switch into one of the boot environments other than current boot environment, use the following command:

CLI (network-admin@switch) > bootenv-activate-and-reboot name netvisor-1

To delete a boot environment, use the following syntax:

CLI (network-admin@switch) > bootenv-delete name netvisor-2

You can display information about different boot environments on the switch.
