[cisco-voip] Simple VOIP question: Switch related

[Gheorghe PLETEA]

The way that I configured the interfaces is :
 

switchport mode access

switchport voice vlan 2

switchport access vlan 3          ; Data VLAN

 
Please try this configuration on the switch, and clean the phone config
with "Erase Configuration" on the     Setings -> Network Configuration .
 
After that let me know if it was solved or not.

I'm having the worst time trying to figure out a problem.

 

The issue is that a 7912 phone seems to be getting an IP address in the
data subnet.  We've tried two configurations on the switchport level and
neither are working...

 

Interface fa0/1

switchport mode access

switchport voice vlan 2

srr-queue bandwidth share 10 10 60 20

priority-queue out

mls qos trust cos

auto qos voip trust

spanning-tree portfast

 

AND/OR

 

Interface fa0/1

Switchport mode trunk

switchport trunk encapsulation dot1q

switchport voice vlan 2

srr-queue bandwidth share 10 10 60 20

priority-queue out

mls qos trust cos

auto qos voip trust

spanning-tree portfast

 

And yet the phone keeps receiving an IP address in the data subnet.

 

We've verified the following:
- helper-address on the router

- correct DHCP scope
