gnmic-set:tldr:4b1cd

This command is using the "gnmic" tool to perform a set operation on a network device using gNMI (gRPC Network Management Interface).

Here is the breakdown of the command:

• gnmic - This is the command to execute the "gnmic" tool.
• --address ${ip:port} - This specifies the address and port of the network device to connect to. The ${ip:port} is an example of a variable placeholder, which should be replaced with the actual IP address and port number, for example, 192.168.1.1:8080.
• set - This indicates that the operation to be performed is a "set" operation which will update a value on the network device.
• --update-path ${path} - This specifies the path of the configuration or operational parameter to be updated on the network device. The ${path} is another variable placeholder, which should be replaced with the actual path, for example, /system/clock/timezone.
• --update-value ${value} - This specifies the value to be set for the parameter specified in the --update-path option. The ${value} is a variable placeholder that should be replaced with the actual value, for example, "America/New_York".

So in summary, the command is instructing the gnmic tool to connect to a network device at a given IP address and port, then perform a set operation by updating a specific parameter identified by the path with a new value.
