DHCP handing out wrong ip on ports.

[pgreen]

I have my access ports set up like this:

PC is tethered from phone on it's internal switch.

interface 2/0/1

switchport access plan 11

switchport voice vlan 130

In the VLANs I have ip helper-address set to my DHCP server.

The phones and the computers pick up either a .11.X address or the default vlan 10.10.2.x

If I manually set the phones to pick up VLAN 11 on the pc port and vlan 130 on the WAN port, it works fine.  I shouldn't have to touch the phones though.  Right?

the phone not select the correct VLAN, 
check mac address is it add to correct vlan ?

[pgreen]

Here’s the exact config

interface GigabitEthernet2/0/5
switchport access vlan 11
switchport voice vlan 130
spanning-tree portfast edge

Here’s the show mac address-table for that interface.

-------------------------------------------

Vlan Mac Address Type Ports
---- ----------- -------- -----
11 3814.287c.d89c DYNAMIC Gi2/0/5
11 805e.c072.3531 DYNAMIC Gi2/0/5
130 805e.c072.3531 DYNAMIC Gi2/0/5

as you can see the VLAN one time 11 and other is 130, 
so return back to the dot1x if you use it there is something misconfig.

[pgreen]

What should the “dot1.q” look like?

[MHM Cisco World]

this all config under the interface 
interface GigabitEthernet2/0/5
switchport access vlan 11
switchport voice vlan 130
spanning-tree portfast edge

what is the SW model you use ?

[MHM Cisco World]

if you dont use dot1x then this bug in cisco switch, take look to link below

I need to know the phone model and SW. 
thanks

try using LLDP instead of CDP and check result, you must see VoIP mac in voice VLAN only. 

[MHM Cisco World]

Yealink Phones <<- use LLDP not CDP and check again 

note:- do this in one port and if you success apply it to other ports

[Reza Sharifi]

Are you using Cisco phones? If yes, the voice vlan (according to your port config) should always be 130 and your data vlan 11. You also need option 150 configured on the DHCP server for the voice vlan.

They are Yealink Phones.

I have configured my access ports as follows:

- The PC is connected via tethering from a phone on the internal switch.
- Interface: 2/0/1
- Switchport access plan: 11
- Switchport voice VLAN: 130

In my VLAN configuration, I have set the "ip helper-address" to my DHCP server.

Currently, both the phones and computers are obtaining IP addresses either from the .11.X subnet or the default VLAN 10.10.2.X subnet.

Ideally, I shouldn't have to manually configure the phones to pick up VLAN 11 on the PC port and VLAN 130 on the WAN port. The configuration should work automatically without any additional manual intervention. Is my understanding correct?
