server from the interface address pool to the client. 
Use the undo dhcp server tftp-server ip-address command to remove the TFTP server address from 
DHCP interface address pool for the client. 
No TFTP server address is specified in a DHCP interface address pool by default. 
Using the dhcp server tftp-server ip-address command repeatedly will overwrite the previous 
configuration.

# Specify the TFTP server IP address 10.1.1.1 in the DHCP interface address pool of VLAN-interface 1 
for the client.
