I have a 3750G fiber distribution switch that I just replace. None of the switched connected to the fiber switch have working phones. All other phones in the campus work.
here is the interface config for the uplink to the core switch.
the phones are on vlan 10 and from the switch I can ping the voice equipment.
<code>
interface GigabitEthernet1/0/1
description UPLINK to FOX052202LT
switchport access vlan 17
switchport trunk encapsulation dot1q
switchport trunk native vlan 17
switchport mode trunk
</code>

Hey,
You need to add vlan 10 to this switch. Go to global configuration mode and add:
#vlan 10
#exit
As from last command output:
Acad_Library_3508#sh vlan id 10
VLAN id 10 not found in current VLAN database
Its telling that vlan 10 is not configured on this switch.
HTH.

Hey,
Make sure you have vlan 10 configured on this replacement switch. Check with command 'show vlan brief' and it should show vlan 10 and list the ports associated to it. Also change the uplink configuration to:
interface GigabitEthernet1/0/1
description UPLINK to FOX052202LT
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk native vlan 17

This is just a distribution switch VLAN17 is the trunk port. the 6500 on the other side does have vlan 10 configured on it. I have changed the config above and added vlan10 to the switch, but phones are still not comming up.

Hey,
Paste the 'show interface trunk' and 'sh vlan id 10' output from this switch.
