Description

Implement gNMI Get operation to retrieve current device configuration state.

Tasks

Wrap pygnmi client for easier use
Implement Get for specific paths
Implement Get for multiple paths in one request
Parse and normalize response data
Handle connection errors gracefully
Support both config and state datastores

API Design

class GNMIClient:
    async def get_config(self, paths: list[str]) -> dict:
        """Get configuration at specified paths"""
        
    async def get_state(self, paths: list[str]) -> dict:
        """Get operational state at specified paths"""
        
    async def get_vlan_config(self) -> list[dict]:
        """Convenience: get all VLAN configuration"""

Example Usage

async with GNMIClient(target="leaf1:6030", credentials=creds) as client:
    vlans = await client.get_config([
        "/openconfig-network-instance:network-instances/network-instance[name=default]/vlans"
    ])

Output

src/gnmi/client.py
