You need to allow vlan 402 as well as vlan 498. You should also be able to use the 'switchport voice vlan' command without the switchport trunk commands.

After a lot of fiddling around and getting nowhere, I'll ask you :) I am trying to set up a test port - for an IP phone actually - with the office WS VLAN (402) native untagged, and the Voice VLAN (498) tagged on this 3560-48 (12.2(25)SEE4). My config looks like this: #sh run int f0/44 interface FastEthernet0/44 description ekb Testport switchport access vlan 402 switchport trunk encapsulation dot1q switchport trunk native vlan 402 switchport trunk allowed vlan 498 switchport mode trunk load-interval 30 end #sh vlan dot1q tag native dot1q native vlan tagging is disabled #sh int f0/44 switchport Name: Fa0/44 Switchport: Enabled Administrative Mode: trunk Operational Mode: trunk Administrative Trunking Encapsulation: dot1q Operational Trunking Encapsulation: dot1q Negotiation of Trunking: On Access Mode VLAN: 402 (VL-workstation) Trunking Native Mode VLAN: 402 (VL-workstation) Administrative Native VLAN tagging: enabled # !!! Voice VLAN: none Administrative private-vlan host-association: none Administrative private-vlan mapping: none Administrative private-vlan trunk native VLAN: none Administrative private-vlan trunk Native VLAN tagging: enabled Administrative private-vlan trunk encapsulation: dot1q Administrative private-vlan trunk normal VLANs: none Administrative private-vlan trunk private VLANs: none Operational private-vlan: none Trunking VLANs Enabled: 498 Pruning VLANs Enabled: 2-1001 Capture Mode Disabled Capture VLANs Allowed: ALL Protected: false Unknown unicast blocked: disabled Unknown multicast blocked: disabled Appliance trust: none The "enabled" in the output seems to be the show's mistake, if a few web pages are to be believed, but... The trunk link to the phone works nicely, but connecting a stupid win xp laptop (phone removed from in between) does not seem to work. Wireshark shows me outgoing broadcast packets (DHCP queries) from my laptop untagged. I see no responses coming in though. Does anyone have an idea where I could find the culprit...?
