gnmic:tldr:ccfd9
The command "gnmic --address ${ip:port} capabilities" is used to fetch the capabilities of a network device using the GNMI (gRPC Network Management Interface) protocol.
Here's a breakdown of the command:
-
"gnmic": This is the name of the command-line tool used to interact with network devices that support the GNMI protocol. It allows you to perform various operations like fetching, setting, and subscribing to telemetry data from these devices.
-
"--address ${ip:port}": This flag specifies the address of the network device you want to communicate with. The "${ip:port}" part is a placeholder that should be replaced with the actual IP address and port number of the device. For example, if the device's IP address is "192.168.1.1" and the GNMI service is running on port 8080, you would replace it as "--address 192.168.1.1:8080".
-
"capabilities": This is the operation you want to perform on the device. By specifying "capabilities", you are requesting information about the device's supported features and functionalities. This includes details about supported models, supported GNMI versions, and other capabilities that the device can offer.
When you run this command, the gnmic tool will establish a connection with the network device at the provided IP address and port. It will then send a "capabilities" request to the device using the GNMI protocol. The device will respond with the requested information, which will be displayed in the terminal.
