Cisco 3750 Switch "DHCP: XID did NOT MATCH in dhcpc_for_us()" ERROR

Receiving the following error on my 3750 switch after connecting to an ADTRAN switch. I trunked the Cisco switch ports with a native VLAN.

Cisco Switch port config;

interface GigabitEthernet3/0/23
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 10
 switchport mode trunk
!
interface GigabitEthernet3/0/24
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 10
 switchport mode trunk

What is the error related to as the Cisco switch is not a DHCP server.

What is the port channel connected to?  Also, can you post similar output from the adtran?

SouljaCommented:
Are you sure dhcp isn't enabled? Can you post the config? Also the two trunk configs, are they part of a port channel or is one blocked by spanning tree?

dhcp helper address is actually enabled on the vlan interfaces

Boom! Exactly! :)

Remove and see if the errors still occur.

solarisjunkieAuthor Commented:
the addresses are acquired via an AD server so if I take the ip helper off that vlan how will they know where to get the dhcp address from. Do I make it a global dhcp helper command?
The adtran switch is servicing our phones which are pulling an ip address from dhcp. Those Adtran switches are connected to the Cisco switches via the trunk ports and they are aslo trunked.

Okay, so you don't want to remove that command, but it's definitely coming from you dhcp relay agent.

Can you post your output for:

sh int trunk

sh spanning-tree vlan 10
