DHCP Client Status

This document provides a brief description of the DHCP Client Status OpEN APIs. It provides the following services:

Example C Application dhcp_client_example

Initialization

In the main function, the sample application initializes the OpEN API RPC service by calling openapiClientRegister() and waits for the RPC service in switchdrvr to start. A Client Handle is returned by openapiClientRegister() which is used while invoking the OpEN APIs. The application then exercises the associated OpEN APIs and logs informational and/or error messages on the console. The example application runs to its completion and exits.

dhcp_client_example

dhcp_client_example.c is a sample application that demonstrates the use of the DHCP Client Status OpEN API. dhcp_client_example is started from the command line and exercises all the DHCP Client Status OpEN APIs one by one.

Sample Output (LiNe/LinuxHost platform)

# ./dhcp_client_example

please enter internal interface number <internal interface="" number>=""> ICOS version = 1.25.18.42 Get the DHCP Client IP Address <IP address>=""> for interface number: <internal interface="" number>=""> SUCCESS Get the DHCP Client subnet mask <subnet mask>=""> for interface number: <internal interface="" number>=""> SUCCESS Get the DHCP Server IP Address <IP address>=""> for interface number: <internal interface="" number>=""> SUCCESS Get the DHCP Options returned by the DHCP Server: SUCCESS
