DHCP Server Responsibilities Description
keeping track of which addresses have been allocated and which
are still available.
Conguration Parameter Storage and Management DHCP servers also store and maintain other parameters that are
sent to clients when requested. These parameters specify in detail
how a client is to operate.
Lease Management DHCP servers use leases to allocate addresses to clients for a
limited time. The DHCP server maintains information about each of
the leases, including lease length.
Responding To Client Requests DHCP servers respond to dierent types of requests from clients,
primarily, granting, renewing, and terminating leases.
Providing Administration Services DHCP servers include functionality that allows an administrator to
implement policies that govern how DHCP performs its other tasks.
Conguring the Server for Automatic Address Allocation
Automatic address allocation is an address assignment method by which the DHCP server leases an IP address to a client from a pool of
available addresses.
An address pool is a range of IP addresses that the DHCP server may assign. The subnet number indexes the address pools.
To create an address pool, follow these steps.
1 Access the DHCP server CLI context.
CONFIGURATION mode
ip dhcp server
2 Create an address pool and give it a name.
DHCP mode
pool name
3 Specify the range of IP addresses from which the DHCP server may assign addresses.
DHCP <POOL> mode
network network/prefix-length
• network: the subnet address.
• prefix-length: species the number of bits used for the network portion of the address you specify.
The prex-length range is from 17 to 31.
4 Display the current pool conguration.

After an IP address is leased to a client, only that client may release the address. Dell EMC Networking OS performs a IP + MAC source
address validation to ensure that no client can release another clients address. This validation is a default behavior and is separate from IP
+MAC source address validation.
