This can be done byadding the port to the voice VLAN manually.Access Not supportedTrunkSupportedMake sure the default VLAN of the port existsand is not a voice VLAN, and the access portpermits the traffic of the default VLAN and thevoice VLAN.Tagged voicetrafficHybridSupportedMake sure the default VLAN of the port existsand is not a voice VLAN, and the default VLANand the voice VLAN is in the list of the taggedVLANs whose traffic is permitted by the accessport.AccessSupportedMake sure the default VLAN of the port is avoice VLAN.TrunkSupportedMake sure the default VLAN of the port is avoice VLAN and the port permits the traffic ofthe VLAN.ManualUntaggedvoicetrafficHybridSupportedMake sure the default VLAN of the port is avoice VLAN and is in the list of untaggedVLANs whose traffic is permitted by the port.IP phones acquiring IP address and voice VLAN through manual configuration canforward only tagged traffic, so the matching relationship is relatively simple, as shown inTable 1-3:
