dhcp-client is launched after the bootstrap. The dhcp-requests of the client contain the
option vendor-class-identifier set to the value "TeleTecMAG200boot". If the dhcp-
answer contains parameter TeleTec.mcip_img and TeleTec.mcport_img, the attempts
to load the image prepared by the client are performed from the multicast group
TeleTec.mcip_img:TeleTec.mcport_img. The parameter TeleTec.ip_log:
TeleTec.ip_port determine the addresses, to which bootstrap attempts to send the
