have to set up a layer 3 switch, with dhcp pools and vlans. I have done this using a method such as:
ip dhcp pool 400
network 10.0.0.0 255.255.255.240
default-router 10.0.0.14
ip dhcp excluded-address 10.0.0.14
int vlan 400
ip address 10.0.0.14 255.255.255.240
ip helper-address 10.0.0.14
ip dhcp pool 800
network 10.0.0.16 255.255.255.240
default-router 10.0.0.30
ip dhcp excluded-address 10.0.0.30
int vlan 800
ip address 10.0.0.30 255.255.255.240
ip helper-address 10.0.0.14
etc
My issue is, every DHCP pool works, for every vlan in the correct range. But it just randomly stops sending out IP's for all VLANS at the same time, it usually does it for about a total of 10-20 PCs with in the network. When I go to show ip dhcp pools, it shows there is still more addresses that can be leased. But when I flick from static to DHCP again, it will auto to a 169 - even though other PC's on the same switch, under the same VLAN will have the corecct 10. address, if I unassign a pc and quickly assign a pc onto dhcp it will then go to the correct address. If I assign statically it works too. I honestly don't know what I am doing wrong... but it seems like the dhcp pools are reaching a limit at the same time? Even thought hey shouldn't be :o
I have also excluded all gateways, to avoid conflicts. I have checked for further conflicts and even tried to remove them(even though there was none)
I have attached the packet tracer file and will post the L3 config file, below this in a comment.
Thanks for any help in advance
