gnmic-subscribe:tldr:843dd
This command is using the tool gnmic to subscribe to a network device using the specified IP address and port.
The -a flag specifies the address and port of the network device, where ${ip:port} is a placeholder that should be replaced with the actual IP address and port.
The subscribe keyword tells gnmic to subscribe to the specified device.
The --path flag specifies the path to the data that needs to be subscribed to. The ${path} placeholder should be replaced with the actual path.
The --mode once flag indicates that gnmic should only receive a single update from the subscribed data and then exit.
Combined, this command is subscribing to a network device specified by the IP address and port, subscribing to the data specified by the path, and receiving only one update before terminating the subscription.
