Configuration Guide 34 Document #: LTRT-31657
Configure the third zone, which accepts packets whose DHCP option 60’s value contains
the text “phone”:
(config-if-VLAN-1)# ip dhcp-server zone z3
(conf-zone z3)# selector option 60 substr phone
(conf-zone z3)#network 20.20.30.5 20.20.30.200 255.255.255.0
(conf-zone z3)#lease 0 1 0
(conf-zone z3)#exit
Configure the default zone to have an address pool in the same subnet as its IP and
activate the dhcp server:
(config-if-VLAN-1)# ip address 20.20.1.1 255.255.0.0
(config-if-VLAN-1)# ip dhcp-server 20.20.1.5 20.20.1.200
255.255.0.0
(config-if-VLAN-1)# ip dhcp-server lease 0 1 0
(config-if-VLAN-1)# service dhcp
