To remove the default gateway, DNS server addresses, and WINS server information for a 
particular VLAN, use the following command:

unconfigure {vlan} <vlan_name> dhcp-options {[ default-gateway | dns-server 

{primary | secondary} | wins-server]}

 

To remove all the DHCP information for a particular VLAN, use the following command:

unconfigure vlan <vlan_name> dhcp

 

You can clear the DHCP address allocation table selected entries, or all entries. You would 
use this command to troubleshoot IP address allocation on the VLAN. To clear entries, use 
the following command:

clear vlan <vlan_name> dhcp-address-allocation [[all {offered | assigned | 

declined | expired}] | <ipaddress>]

 

Displaying DHCP Information

To display the DHCP configuration, including the DHCP range, DHCP lease timer, network 
login lease timer, DHCP-enabled ports, IP address, MAC address, and time assigned to each 
end device, use the following command:

show dhcp-server {vlan <vlan_name>}

 

To view only the address allocation of the DHCP server on a VLAN, use the following 
command:

show vlan <vlan_name> dhcp-address-allocation

 

To view only the configuration of the DHCP server on a VLAN, use the following command:

show {vlan} <vlan_name> dhcp-config
