IP Address Type

Use the drop-down list to select the type of addresses that the server node will allocate.

Options: IPv4 or IPv6

Default: IPv4

Tcl Parameter: DhcpSrvIpType

T1 Option

Select to include the Renewal Time Value option in messages sent to the client. This option indicates that the client should renew its lease with the server when the timer expires. The client will send a unicast request to the server in an attempt to extend its lease. The T1 timer default is 0.5 x the duration of the lease.

Tcl Parameter: DhcpSrvIncT1OptionEnabled

T2 Option

Select to include the Rebinding Time Value option in messages sent to the client. This option indicates that the client should rebind its address with a server if it has not received an acknowledgement to a renewal request when the timer expires. The client will send a broadcast request in an attempt to extend its lease. The T2 timer default is 0.875 x the duration of the lease.

Tcl Parameter: DhcpSrvIncT2OptionEnabled

Request Wait Time

The number of milliseconds that the server node will wait for a message from the client in response to a DHCPOFFER (IPv4) or Advertise (IPv6) message. If the request is not received before the timer expires, the server node releases the address reserved for the client back to the address pool.

Range: 0 — 1,000,000

Default: 1000
