I have enabled Ter mon,
And the command that I used for debug are: debug ip dhcp server packet
detail, debug ip dhcp server events, debug ip dhcp server class.
here is the config:
ip dhcp pool Voice
network 177.3.11.0 255.255.255.0
default-router 177.3.11.1
option 150 ip 177.1.254.3
class Phone1
address range 177.3.11.50 177.3.11.50
class Phone2
address range 177.3.11.60 177.3.11.60
!
!
ip dhcp class Phone1
option 60 hex 123456
!
ip dhcp class Phone2
option 60 hex 123456
R3#sh debug
DHCP server packet detail debugging is on.
DHCP server event debugging is on.
DHCP server class debugging is on.
And here is the debug output that I get using those debug command:
Nov 21 15:49:49.307: DHCPD: Sending notification of ASSIGNMENT:
