DCHP Client Specific User Configurations

• DHCP Request Time-out (in sec):

  • Defines how long to wait before a DHCP lease is acquired when the DHCP module is enabled

  • Value is in seconds

  • Default value: 10

  • Symbol TCPIP_DHCP_TIMEOUT

• DHCP Host Name Maximum Size:

  • Default value: 20

  • Symbol TCPIP_DHCP_HOST_NAME_SIZE

  • The DHCP task processing rate: number of milliseconds to generate an DHCP tick.

  • Used by the DHCP state machine

  • The lower the rate (higher the frequency) the higher the module priority and higher module performance can be obtained

  • Default value: 67

  • Symbol TCPIP_DHCP_SERVER_LISTEN_PORT

• Enable the time server option:

  • Enables the request of the time server option

  • Default value: 0

  • Symbol TCPIP_DHCP_USE_OPTION_TIME_SERVER

• Maximum Number of Time Servers to Store:

  • Max number of time server addresses to store

  • Should be less than 256!

  • Only if TCPIP_DHCP_USE_OPTION_TIME_SERVER is enabled

  • Default value: 1

  • Symbol TCPIP_DHCP_TIME_SERVER_ADDRESSES, TCPIP_DHCP_OPTION_TIME_SERVER_MAX

• Enable the NTP server option:

  • Enables the request of the NTP server option

  • Default value: 0

  • Symbol TCPIP_DHCP_USE_OPTION_NTP_SERVER

• Maximum Number of NTP Servers to Store:

  • Max number of NTP server addresses to store

  • Should be less than 256!

  • Only if TCPIP_DHCP_USE_OPTION_NTP_SERVER is enabled

  • Default value: 1

  • Symbol TCPIP_DHCP_NTP_SERVER_ADDRESSES, TCPIP_DHCP_OPTION_NTP_SERVER_MAX

• Enable the DHCP client:

  • Default value for the enable/disable the DHCP client at stack start-up.

  • Note: the interface initialization setting in TCPIP_NETWORK_CONFIG takes precedence!

  • Default value: none

  • Symbol TCPIP_DHCP_CLIENT_ENABLED

• Boot File Name Option:

  • Enable the usage of the Boot file name received from the DHCP server

  • Default value: false

  • Symbol TCPIP_DHCP_STORE_BOOT_FILE_NAME

• Boot file name storage size:

  • Size of the storage for the Boot file name

  • should always be <= 128

  • Default value: 128

  • Symbol TCPIP_DHCP_BOOT_FILE_NAME_SIZE
