Perform a large gNMI Set and immediately reboot the device to verify that the configuration is in place after the device comes up and the configuration database is functional and unlocked.

• featureprofiles/topologies/dut.testbed

• Configure 200 LAG interfaces with 2 member interfaces each on the DUT.
• Configure another 300 LAG interfaces with 1 member interface each on the DUT.
• This results in a total of 500 LAG interfaces and 700 member/physical interfaces.

• Step 1: Create a gNMI batch configuration to:
  • Configure description on all the 700 Physical and 500 LAG interfaces.
  • Configure IPv4 and IPv6 Addresses on all the 500 LAG interfaces.
• Step 2: In a Goroutine, use gNMI Batch Set to set the configuration on the DUT.
• Step 3: In a separate Goroutine (running in parallel), trigger a complete chassis cold reboot using the gnoi.system.System.Reboot RPC with the method set to COLD.
• NOTE: rpc error: code = Unavailable desc = transport is closing or a similar message for the gNMI connection is acceptable since the reboot RPC response is not sent over the same connection from which the gNMI Set request was sent.
• Step 4: Wait for the device to boot up and return to service.

• Step 1: Verify boot time using /system/state/boot-time and software versions using /components/component/state/software-version.
• Step 2: Using gNMI Get, verify that the interface descriptions and IP addresses applied in SYS-5.1.1 are present in the configuration.
• Step 3: Issue a gNMI Set request to configure a test description on any one DUT interface.
• Step 4: Verify that the gNMI Set request succeeds (indicating the configuration database is unlocked and commits are functional).
• Step 5: Verify the new description is applied correctly using a gNMI Get request.
