Figure 6.1 DHCP service running on a WS5100.
DHCP allows hosts on an IP network to request and be assigned IP addresses and discover information about
the network to which they are attached. The Network administrator configures address pools for each
subnet. Whenever a DHCP client in subnet requests IP address, the DHCP server assigns an IP address from
the address pool configured for that subnet.
When the DHCP server allocates an address for a DHCP client, the client is assigned a lease. The lease
expires after an interval defined by the administrator. Before leases expire, the clients to which leases are
assigned are expected to renew them to continue to use the addresses. Once a lease has expired, the client
is no longer permitted to use the leased IP address.

6.2 Managing the DHCP Server

The purpose of the DHCP Server is to assign IP addresses to hosts and provide a method clients can request
IP addresses and configuration information.
DHCP can be configured using either:
• CLI
• SNMP
• Web UI

6.3 Configuring DHCP Server using the CLI

DHCP configuration is accomplished by creating pools and mapping them to L3 interfaces (SVI).
A pool can be configured either as a network pool or host pool.
• A Network pool is the pool having include ranges. When this network pool is mapped to a L3 interface,
the DHCP clients requesting IPs from this L3 interface will get an IP from a range of available addresses.
• A host pool is used to assign static/fixed IP address to DHCP clients.
