Configure a DHCP Server to Statically Allocate IP Addresses

Network Requirements

  • Device2 acts as a DHCP server to allocate IP addresses, gateway IP addresses, and DNS server IP addresses in a static manner.
  • The DHCP server allocates an IP address to PC in MAC binding mode.

Configuring a DHCP Server to Statically Allocate IP Addresses

Figure 3-1 Configuring a DHCP Server to Statically Allocate IP Addresses

Configuration Steps

Step 1: Configure the IP address of the Device2 interface and works in the DHCP server mode.

Device2#configure terminal
Device2(config)#interface vlan2
Device2(config-if-vlan2)#ip address 1.0.0.3 255.255.255.0
Device2(config-if-vlan2)#ip dhcp server
Device2(config-if-vlan2)#exit

Step 2: Configure the static binding address pool and parameters.

#Configure the address pool mac-binding, and adopt the static mac binding mode to distribute IP address for the PC.

Device2(config)#ip dhcp pool mac-binding
Device2(dhcp-config)#range 1.0.0.4 1.0.0.254 255.255.255.0
Device2(dhcp-config)#bind 1.0.0.11 00e0.00c1.013d
Device2(dhcp-config)#default-router 1.0.0.1
Device2(dhcp-config)#dns-server 1.0.0.2
Device2(dhcp-config)#exit

Step 3: Check the result.

#On Device2, query the associated address pool of the interface via the show ip dhcp server interface vlan2 command.

Device2(config)#exit 
Device2#show ip dhcp server interface vlan2
DHCP server status information: 
DHCP server is enabled on interface: vlan2
Vrf : global 
DHCP server pool information:

1.0.0.3/24        mac-binding          1.0.0.4 – 1.0.0.254  0.00% 

#On Device2, query the binding IP address distributed for the PC via the show ip dhcp pool mac-binding binding command.

Device2#show ip dhcp pool mac-binding binding

------------   -----------------  ------------ ------    ------------

#On Device2, query the address distributed for the PC via the show ip dhcp pool mac-binding lease command.

Device#show ip dhcp pool danymic-pool2 lease 
IP Address        MAC Address        Vendor Id       Type     Time Left(s) 
--------------    ---------------    ----------      -------  -------------
1.0.0.11          00e0.00c1.013d     Global          Lease    107980 

On the PC, check whether the got IP address, gateway IP address, and DNS server address are correct.
