The gnmic get command is a part of the gnmic tool, which is used for interacting with network devices using the gNMI (gRPC Network Management Interface) protocol. The get command specifically allows users to retrieve a snapshot of operational data from a gNMI-enabled network device.
Here are key points about the gnmic get command:
- Purpose: The primary purpose of the get command is to request and retrieve information about the operational state of a network device that supports the gNMI protocol.
- Snapshot of Operational Data: When you execute gnmic get, the tool communicates with the target network device over gNMI and requests a snapshot of its current operational data. This can include information such as device configuration, performance metrics, and other relevant parameters.
- gNMI Protocol: gNMI is a protocol that facilitates the exchange of management information between a network device and a management system. It is based on gRPC (gRPC Remote Procedure Call) and is designed to be efficient and scalable for network management operations.
- Documentation: Users can refer to the documentation for the gnmic get command for more details on its usage, command-line options, and examples. The provided link https://gnmic.kmrd.dev/cmd/get likely contains comprehensive information about using the get command with gnmic.
gnmic Command Examples
1. Get a snapshot of the device state at a specific path:
# gnmic --address ip:port get --path path
2. Query the device state at multiple paths:
# gnmic -a ip:port get --path path1 --path path2
3. Query the device state at multiple paths with a common prefix:
# gnmic -a ip:port get --prefix prefix --path path1 --path path2
4. Query the device state and specify reponse encoding (json_ietf):
# gnmic -a ip:port get --path path --encoding json_ietf
Summary
To use the gnmic get command effectively, users should understand the specific data models and paths supported by the target network device, as gNMI operates based on YANG models that define the structure and semantics of the data exchanged.
In summary, the gnmic get command is a valuable tool for network administrators and operators who need to retrieve real-time operational data from gNMI-enabled devices, contributing to efficient network monitoring and management.
