| Macros | |
| TCPIP_DHCPS_DEFAULT_IP_ADDRESS_RANGE_START | These below IPv4 DHCP server address details are default address and it is assigned to the network default network interface. for Other interfaces , tcpip_stack_init.c file should be use to configure DHCP_POOL_CONFIG. IPv4 Address range is starting from 100, because the from 1 to 100 is reserved. Reserved Address will be used for the gateway address. Start of IP address Range , network_config.h ipaddress and this start of IP address should be in same SUBNET RECOMENDED - network_config.h ipaddress should be 192.168.1.1 if DHCP server ip address range starts from 192.168.1.100. |
| TCPIP_DHCPS_DEFAULT_SERVER_IP_ADDRESS | DHCP server Address per interface. DHCP server Address selection should be in the same subnet. |
| TCPIP_DHCPS_DEFAULT_SERVER_NETMASK_ADDRESS | DHCP server subnet Address per interface. |
| TCPIP_DHCPS_DEFAULT_SERVER_PRIMARY_DNS_ADDRESS | DHCP server DNS primary Address |
| TCPIP_DHCPS_DEFAULT_SERVER_SECONDARY_DNS_ADDRESS | DHCP server DNS Secondary Address |
| TCPIP_DHCPS_LEASE_DURATION | Timeout for a solved entry in the cache, in seconds the entry will be removed if the TMO elapsed and the entry has not been referenced again |
| TCPIP_DHCPS_LEASE_ENTRIES_DEFAULT | The Maximum Number of entries in the lease table Default total number of entries for all the the interface |
| TCPIP_DHCPS_LEASE_REMOVED_BEFORE_ACK | Timeout for a unsolved entry , in seconds and should be removed from the entry if there is no REQUEST after OFFER |
| TCPIP_DHCPS_LEASE_SOLVED_ENTRY_TMO | Timeout for a solved entry in the cache, in seconds. The entry will be removed if the TMO lapsed and the entry has not been referenced again |
| TCPIP_DHCPS_TASK_PROCESS_RATE | DHCPS task processing rate, in milliseconds. The DHCPS module will process a timer event with this rate for maintaining its own queues, processing timeouts, etc. Choose it so that the other TMO are multiple of this The default value is 200 milliseconds. The lower the rate (higher the frequency) the higher the module priority and higher module performance can be obtained The value cannot be lower than the TCPIP_STACK_TICK_RATE. |
