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 100
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 100
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.

| NOTE: From the above output, we can see that the DHCP server provided us with two DNS servers as specified by the line: DNS0: 172.16.1.254, DNS1: 172.16.2.254 as well as two WINS servers, as specified by the line NBNS0: 10.1.1.254, NBNS1: 10.2.2.254. The Subnet mask is /24 and the DNS domain provided is howtonetwork.net. If a workstation, such as a Windows-based computer were provided IP addressing information from the same DHCP server and we issued ipconfig /all at the command prompt, we would see:
