NO DHCP Address assigned

Hi

I'm studying for part one of CCNA, but meantime my new job has thrown me in feet first into their Nexus3000/1841/1811 plus some HP procurve switch environment and I"m expected to know advanced troubleshooting.

 

So the problem, we have a Ruckus wifi controller here in our main office and two remote sites connect via MPLS but with public data access for guest user access that is blocked form our domain

In one remote office (NYC) they have one Access point with two LAN ports, one is vlan1 for office connectivity and goes though network switch to rest of network. That side is fine.

On the second LAN port  (vlan2) the guest network where they need to be provided a temporary token to login and enter this on a web page. They are SUPPOSED to get DHCP assignment from the 1811

This is config on DHCP

no ip dhcp use vrf connected
ip dhcp excluded-address 10.1.1.1
!
ip dhcp pool GuestUsers
   network 10.1.1.0 255.255.255.240
   dns-server 192.168.1.182 192.168.1.76
   default-router 10.1.1.1

 

And used on VLan2 interface connected to Fastethernet3

interface FastEthernet3
 switchport access vlan 2
 speed 10
 no cdp enable

!
interface Vlan2
 description Guest Users DMZ
 ip address 10.1.1.1 255.255.255.240
 ip access-group 120 in
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 ip wccp web-cache redirect in
 ip flow ingress
 ip nat inside
 ip virtual-reassembly in
 ip tcp adjust-mss 1412

 

and the access list

access-list 120 permit udp any host 192.168.1.76 eq domain
access-list 120 permit udp any host 192.168.1.182
access-list 120 permit ip host 192.168.20.181 any
access-list 120 deny   ip 10.1.1.0 0.0.0.255 192.168.0.0 0.0.255.255
access-list 120 permit ip 10.1.1.0 0.0.0.255 any
access-list 120 permit udp any eq bootpc any eq bootps

 

where the 192.168.x.x  are internal DNS and a Web filtering device.

 

Before I arrived this stopped working, (so I know I didn't do it) they are not getting any response from the DHCP server,

  DHCP server: ANY (255.255.255.255)
    Leases:   0
    Offers:   0      Requests: 0     Acks : 0     Naks: 0
    Declines: 0      Releases: 0     Query: 0     Bad: 0
    Forcerenews: 0      Failures: 0

 

Anyone have a guess, can I configure VRF to force the interface to use the DHCP scope defined?

 

Any help is appreciated.

 

Thanks

David

The first question that comes to mind is what does the F3 interface connect to? Assuming it is a switch, then is that port in the proper VLAN?
