3850 Switch port based DHCP not working

[MarkStites_2]

I have a 3850 WS-C3850-48T-E. I've been trying to get port based DHCP working by following this guide:

http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipaddr_dhcp/configuration/xe-3se/3850/dhcp-xe-3se-3850-book/dhcp-prt-bsd-aa.html

It is not working. I've tried a number of interface names such as "Gi1/0/31" and "GigabitEthernet1/0/31" but none of these work. Plain Jane normal, DHCP works just fine.

I'm experiencing this issue with the following IOS's:

cat3k_caa-universalk9ldpe.SPA.03.06.00.E.152-2.E.bin
cat3k_caa-universalk9.SPA.03.03.03.E.150-1.EZ3.bin

----config snippet------

ip dhcp use subscriber-id client-id
ip dhcp subscriber-id interface-name
ip dhcp excluded-address 172.16.0.1 172.16.6.0
!
!
ip dhcp pool test
 network 172.16.0.0 255.255.248.0
 default-router 172.16.6.254
   address 172.16.6.1 client-id "Gi1/0/31" ascii

   !!!!! Have also tried: address 172.16.6.1 client-id "GigabitEthernet1/0/31" ascii !!!!!!

Any hints? I've Wiresharked the port in question and the DHCP events look normal. My client only receives the first available normal DHCP 172.16.6.2. I always makes sure I release the binding on the client and the switch when trying different combinations.

I have a funny feeling the interface nomenclature may be at fault.

Thanks!

Hi

My take on this is, lets say for interfaces gi1/0/31-48

!
ip dhcp use subscriber-id client-id
ip dhcp subscriber-id interface-name
ip dhcp excluded-address 172.16.0.1 172.16.6.0
!
!
ip dhcp pool test
 network 172.16.0.0 255.255.248.0
 default-router 172.16.6.254
 domain-name yournet.com
 dns-server 1.1.1.1 2.2.2.2 3.3.3.3 
!
!
int range gi1/0/31 - gi1/0/48
ip dhcp server use subscriber-id client-id
!
end

Can you test something like that

Regards
Alex

I have the same problem with a new 3850.  The Port-Based DHCP worked on a 3750, but after transferring the config it does no work on the 3850.
