If the switch is powered down or restarted, MSS does not retain the 
values received from the DHCP server. However, if the IP interface goes 
down but MSS is still running, MSS attempts to reuse the address when 
the interface comes back up.

To configure the DHCP client on a 

VLAN, use the following command:

set interface vlan-id ip dhcp-client {enable | disable}

The vlan-id can be the VLAN name or number. 

The following command enables the DHCP client on VLAN corpvlan:

WX1200# set interface corpvlan ip dhcp-client enable
success: change accepted.

You can configure the DHCP client on more than one VLAN, but the 
client can be active on only one VLAN. 

To remove all IP information from a VLAN, including the DHCP client and 
user-configured DHCP server, use the following command:

clear interface vlan-id ip

The IP interface table flags the address assigned by a DHCP server with an 
asterisk ( * ). In the following example, VLAN corpvlan received IP address 
10.3.1.110 from a DHCP server.
