The NISH client can interactively configure multiple SR OS nodes that share a specific device-label group. Interactive configuration of multiple SR OS nodes uses the combined schema. This means that only configuration options that can be applied to all nodes in the group are available to the operator. Context-sensitive help and auto-completion are supported using the combined schema. See Multinode combined schemas for more information.
When you configure multinode interactive mode, the NISH client immediately places entries into the exclusively locked candidate configuration of every SR OS node in the group. Exiting the interactive configuration mode of a device-label group releases the exclusive lock on all devices that are part of the group. In-progress configuration changes that are stored in the candidate configuration but not committed are lost.
Only one device-label group at a time can hold the configuration lock. If the operator attempts to obtain a configuration lock from another device-label group, the system issues a prompt to release the previous lock. When the system releases the lock, all uncommitted configuration changes are discarded.
