Hi Folks,

i have a strange problem whereby my dchp scope exclusions do not seem to be taking effect... as you can see I have defined my excluded address ranges but the pools show 254 addresses.  Why?

no ip dhcp use vrf connected

ip dhcp excluded-address 192.168.16.1 192.168.16.100

ip dhcp excluded-address 192.168.17.1 192.168.17.10

!

ip dhcp pool ITS

   network 192.168.16.0 255.255.255.0

--More--            option 150 ip 192.168.16.1

   default-router 192.168.16.1

   dns-server 192.168.1.25 192.168.1.2 64.115.0.9 64.115.0.10

!

ip dhcp pool ITS_Phones

   network 192.168.17.0 255.255.255.0

   option 150 ip 192.168.16.1

   default-router 192.168.17.1

   dns-server 192.168.1.25 192.168.1.2 64.115.0.9 64.115.0.10

 

Pool ITS :

Utilization mark (high/low)    : 100 / 0

Subnet size (first/next)       : 0 / 0

 Total addresses                : 254

Leased addresses               : 28

Pending event                  : none

1 subnet is currently in the pool :

Current index        IP address range                    Leased addresses

192.168.16.185       192.168.16.1     - 192.168.16.254    28

 

Pool ITS_Phones :

Utilization mark (high/low)    : 100 / 0

Subnet size (first/next)       : 0 / 0

 Total addresses                : 254

Leased addresses               : 12

Pending event                  : none

1 subnet is currently in the pool :

Current index        IP address range                    Leased addresses

192.168.17.21        192.168.17.1     - 192.168.17.254    12

Hi,
try to type command "show ip dhcp binding" to see which addresses are assigned to clients.

You will see that excluded addresses are not assigned.
