About Session Manager
Session Manager allows you to implement your configuration changes in batch mode. Session Manager works in the following phases:
Configuration session—Creates a list of commands that you want to implement in Session Manager mode.
Validation—Provides a basic semantic check on your configuration. Cisco NX-OS returns an error if the semantic check fails on any part of the configuration.
Verification—Verifies the configuration as a whole, based on the existing hardware and software configuration and resources. Cisco NX-OS returns an error if the configuration does not pass this verification phase.
Commit—Cisco NX-OS verifies the complete configuration and applies the changes to the device. If a failure occurs, Cisco NX-OS reverts to the original configuration.
Abort—Discards the configuration changes before implementation.
You can optionally end a configuration session without committing the changes. You can also save a configuration session.
Session Manager sessions remain available after a supervisor switchover. Sessions are not persistent across a software reload.
