Lab 70 Solution: Configuring IOS DHCP Server

Task 1:

For reference information on configuring hostnames, please refer to:

Lab 35 Configuration and Verification Task 1

Task 2:

Sw1#config t

Enter configuration commands, one per line.  End with CNTL/Z.

Sw1(config)#vlan 50

Sw1(config-vlan)#name DHCP_VLAN

Sw1(config-vlan)#exit

Sw1(config)#interface range fastethernet0/2 — 3

Sw1(config-if-range)#switchport mode access

Sw1(config-if-range switchport access vlan 50

Sw1(config-if-range)#spanning-tree portfast

%Warning: portfast should only be enabled on ports connected to a single

host. Connecting hubs, concentrators, switches, bridges, etc… to this

interface  when portfast is enabled, can cause temporary bridging loops.

Use with CAUTION

%Portfast will be configured in 2 interfaces due to the range command

but will only have effect when the interfaces are in a non-trunking mode.

Sw1(config-if-range)#no shutdown

Sw1(config-if-range)#end

Task 3:

R1#config t

Enter configuration commands, one per line.  End with CNTL/Z.

R1(config)#ip dhcp pool CCNA-DHCP-POOL

R1(dhcp-config)#network 172.16.1.0 255.255.255.0

R1(dhcp-config)#dns-server 10.1.1.254

R1(dhcp-config)#netbios-name-server 10.2.2.254

R1(dhcp-config)#default-router 172.16.1.1

R1(dhcp-config)#domain-name howtonetwork.net

R1(dhcp-config)#lease 5 0 30

R1(dhcp-config)#end

R1#show ip dhcp pool CCNA-DHCP-POOL

Pool CCNA-DHCP-POOL :

1 subnet is currently in the pool :

Current index        IP address range                    Leased addresses

172.16.1.1           172.16.1.1       – 172.16.1.254      0

Task 4:

R1#show ip dhcp binding

Bindings from all pools not associated with VRF:

IP address          Client-ID/              Lease expiration        Type

Hardware address/

User name

172.16.1.2          0100.1d09.d402.38       Mar 06 1993 04:12 AM    Automatic
