Description: The full path of the release to be used the next time the device restarts. There is no guarantee that the file referenced exists (i.e. it may have been deleted since the boot path was last set).

Only one set operation can be executed at a time across all SNMP users, and an operation may not be started unless the current value of nextBootSetStatus is 'idle'. The path must not contain whitespace characters.

Immediately upon setting this object, the system will attempt to set the new boot path, and the process will continue on the device until it has completed or a failure occurs. The current status of the operation can be determined by reading nextBootSetStatus, and the result of the last completed operation is indicated by nextBootLastSetResult.

This object can be set with an empty string in order to clear the current boot firmware. Otherwise, the path should be of the form 'flash:/filename.rel' or 'card:/filename.rel'.

There are several requirements that must be met in order to set a boot release file successfully: - The file must exist. - The file must be in the root of flash (on the active master in a stacked environment) or card. - The file must not be the same as the currently set backup release. - The file must have a .rel suffix. - The file must be a valid release file. - In a stacked environment, there must be enough disk space available to store the release file on each stack member. - The device must have a current release license for the specified release.
