I’m having the worst time trying to figure out a problem.<br>
<br>
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…<br>
<br>
Interface fa0/1<br>
switchport mode access<br>
switchport voice vlan 2<br>
srr-queue bandwidth share 10 10 60 20<br>
priority-queue out<br>
mls qos trust cos<br>
auto qos voip trust<br>
spanning-tree portfast<br>
<br>
AND/OR<br>
<br>
Interface fa0/1<br>
Switchport mode trunk<br>
switchport trunk encapsulation dot1q<br>
switchport voice vlan 2<br>
srr-queue bandwidth share 10 10 60 20<br>
priority-queue out<br>
mls qos trust cos<br>
auto qos voip trust<br>
spanning-tree portfast<br>
<br>
And yet the phone keeps receiving an IP address in the data subnet.<br>
<br>
We’ve verified the following:<br>
- helper-address on the router<br>
- correct DHCP scope<br>
<br>
