ip dhcp pool pool-name

exit
Purpose
Creates a name for the DHCP server address pool
and enters DHCP pool configuration mode.
Specifies the IP address of the DHCP address pool
and the optional mask or number of bits in the
address prefix, preceded by a forward slash.
Specifies the TFTP server address from which the
Cisco IP phone downloads the image configuration
file. This needs to be the IP address of Cisco Unified
CM.
Specifies the router to which the 
Cisco Unified IP phones are connected directly.
This router should be the Cisco Unified SRST
•
router because this is the default address that is
used to obtain SRST service in the event of a
WAN outage. As long as the Cisco IP phones
have a connection to the Cisco Unified SRST
router, the phones are able to get the required
network details.
Exits DHCP pool configuration mode.
