3750 with Shoretel Phones

Hello All,

I am configuring a new 3750 switch that will trunk both voice and data on the same ports. My port config is the following.

 switchport access vlan 11
 switchport mode access
 switchport voice vlan 8
 no cdp enable
 spanning-tree portfast

 

The issue I am running into is the phone cannot contact the HQ server on a different VLAN.

The workstation gets the proper IP and works fine.

If I change the port to switchport access vlan 8 the phone works fine, but not when I try to use the trunk.

I have attached my full config, any help to troubleshoot this trunking issue would be great.

 

Cheers

The configuration that you

The configuration that you show us with an access vlan for data and a voice vlan works well when the phones are Cisco but appears to not work with your Shoretel phones. I would suggest that you configure these ports as trunk ports (and probably limit the trunks to vlans 8 and 11).
