• Verifying Session Manager Configuration, page 23-4
Information 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 implements the changes atomically
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.
Configuration Guidelines and Limitations
Session Manager has the following configuration guidelines and limitations:
• Session Manager supports only the ACL feature.
• You can create up to 32 configuration sessions.
• You can configure a maximum of 20,000 commands across all sessions.
