What if the SU gets to dhcp_state, receives an IP address but fails on other parameters?

A. Other parameters that the SU requires are the TFTP server address, the Time of Day (TOD) server address, the Time Zone (TX) offset value, and the DHCP config file name (also called the DOCSIS config file). These parameters must all be present in the DHCP response from the DHCP server. Note: You can configure the HE to play the part of the DHCP/TFTP server. If the HE is not configured to be the DHCP/TFTP server, make sure that there is a radio helper-address command configured under the HE radio interface. This ensures that DHCP broadcasts are forwarded to the correct server. If you use an external DHCP/TFTP server, the server must also contain a route or default gateway that instructs how to send packets back to the SU network. These error messages point to the absence of optional parameters in the DHCP response: DHCP_ERROR_ACQUIRING_SEC_SVR_ADDR DHCP_ERROR_ACQUIRING_LOG_ADDRESS Configure the secondary server and log server address on the DHCP server to eliminate these errors.
