netInterface is set down when in DHCP/BOOTP mode and link up event occurs

          Details

          • Sprint:
            EIP PI8-IT2 (Oct 13 - Oct 24)
          • Account:
            SPC TCP_IP (SPCTCPIP)

            Description

            The current implementation is inconsistent in the way it uses the interface status (IF-UP / IF-DOWN) when executing the DHCP/BOOT client functionality.

            When starting DHCP (discover) the IP address is set to zero internally and the interface is set to IF-UP.
            In case there is a link up event, the DHCP process is restarted with IP address being set to 0, but setting the Interface state to IF_DOWN.

            Therefore, the stack behaves differently depending on whether or not a link up event occurred.
