| Property | Description |
|---|---|
| add-arp (yes | no; Default: no) | Whether to add dynamic ARP entry. If set to no either ARP mode should be enabled on that interface or static ARP entries should be administratively defined in /ip arp submenu. |
| address-pool (string | static-only; Default: static-only) | IP pool, from which to take IP addresses for the clients. If set to static-only, then only the clients that have a static lease (added in the lease submenu) will be allowed. |
| allow-dual-stack-queue (yes | no; Default: yes) | Creates a single simple queue entry for both IPv4 and IPv6 addresses, and uses the MAC address and DUID for identification. Requires IPv6 DHCP Server to have this option enabled as well to work properly. |
| always-broadcast (yes | no; Default: no) | Always send replies as broadcasts even if the destination IP is known. Will add additional load on L2 network. |
| authoritative (after-10sec-delay | after-2sec-delay | yes | no; Default: yes) | Option changes the way how a server responds to DHCP requests:
|
| bootp-lease-time (forever | lease-time | time; Default: forever) | Accepts two predefined options or time value:
|
| bootp-support (none | static | dynamic; Default: static) | Support for BOOTP clients:
|
| client-mac-limit (integer | unlimited; Default: unlimited) | Specifies whether to limit a specific number of clients per single MAC address or leave unlimited. Note that this setting should not be used in relay setups. |
| conflict-detection (yes | no; Default: yes) | Allows disabling/enabling conflict detection. If the option is enabled, then whenever the server tries to assign a lease it will send ICMP and ARP messages to detect whether such an address in the network already exists. If any of the above get a reply address is considered already used. |
| delay-threshold (time | none; Default: none) | If the sec's field in the DHCP packet is smaller than the delay threshold, then this packet is ignored. If set to none - there is no threshold (all DHCP packets are processed) |
| dhcp-option-set (name | none; Default: none) | Use a custom set of DHCP options defined in the option sets menu. |
| insert-queue-before (bottom | first | name; Default: first) | Specify where to place dynamic simple queue entries for static DCHP leases with a rate-limit parameter set. |
| interface (string; Default: ) | The interface on which the DHCP server will be running. |
| lease-script (string; Default: "") | A script that will be executed after a lease is assigned or de-assigned. Internal "global" variables that can be used in the script:
|
| lease-time (time; Default: 10m 30m) | The time that a client may use the assigned address. The client will try to renew this address after half of this time and will request a new address after the time limit expires. |
| name (string; Default: ) | Reference name |
| parent-queue (string | none; Default: none) | A dynamically created queue for this lease will be configured as a child queue of the specified parent queue. |
| relay (IP; Default: 0.0.0.0) | The IP address of the relay this DHCP server should process requests from:
|
| server-address (IP; Default: 0.0.0.0) | The IP address of the server to use in the next step of the client's bootstrap process (For example, to assign a specific server address in case several addresses are assigned to the interface) |
| use-framed-as-classless (yes | no; Default: yes) | Forward RADIUS Framed-Route as a DHCP Classless-Static-Route to DHCP-client. Whenever both Framed-Route and Classless-Static-Route are received Classless-Static-Route is preferred. |
| use-radius (yes | no | accounting; Default: no) | Whether to use RADIUS server:
