Creating a dhcp pool for a subinterface

[npranger]

Hello,

I have a subinterface on port 0/0 on a 2911 Cisco router.  This is a gigabit port.  However I don't see a command to create a dhcp pool for each of the vlans.  Please help lead me to the correct syntax on this particular router.  Thanks

the router dont care about VLAN except the case you have EtherModule
in your case what you need only 
ip dhcp pool POOL1
default router <subinterface-IP1>

ip dhcp pool POOLx
default router <subinterface-IPx>

that it 
NOTE:- add network command under dhcp pool in same subnet with subinteface you select as default router

Thank you, do i put this command under the
Config-if# interface g0/0
Or under just
Config#

Thanks for such a quick response. Much appreciated

You are so so welcome 
if you face issue share the config you run and I will check it.
NOTE:- also please if you can share topology

It seems a large part of the issue of the original poster is where are the commands entered (in which config mode) and the answer is that the dhcp pool is configured in global config mode. The dhcp pool has parameters for the subnet that will match the subnet configured on the router subnet. So the subinterface will use the dhcp pool but the pool is not configured on the subinterface.

Not sure what you are expecting to see, The dhcp scopes will relate to the L3 interfaces on the router ( including sub -interfaces)

example:
int gigx/x.10
encapsulation dot1q 10
ip address 10.10.10.254 255.255.255.0

int gigx/x.20
encapsulation dot1q 20
ip address 20.20.20.254 255.255.255.0

ip dhcp pool lan
network 10.10.10.0 255.255.255.0
network 20.20.20.0 255.255.255.0 secondary
override default-router 20.20.20.254
default-router 10.10.10.254
lease 0 8
