the aging time, the switch will remove this port from voice VLAN. Voice ports are automatically added into or removed from voice VLAN. Manual Mode: You need to manually add the port of IP phone to voice VLAN, and then the switch will assign ACL rules and configure the priority of the packets through learning the source MAC address of packets and matching OUI address. In practice, the port voice VLAN mode is configured according to the type of packets sent out from voice device and the link type of the port. The following table shows the detailed information. Port Voice VLAN Mode Voice Stream Type Link type of the port and processing mode ACCESS: Not supported. TAG voice stream Automatic Mode TRUNK: Supported. The default VLAN of the port can not be voice VLAN. GENERAL: Supported. The default VLAN of the port can not be voice VLAN and the egress rule of the access port in the voice VLAN should be TAG. ACCESS: Not supported. UNTAG voice stream TRUNK: Not supported. GENERAL: Not Supported. ACCESS: Not supported. Manual Mode TAG voice stream TRUNK:Supported. The default VLAN of the port can not be voice VLAN. And the port should belong to the voice VLAN and the default VLAN. GENERAL:Supported. The default VLAN of the port can not be voice VLAN. The port should be an untagged port in its default VLAN, and a tagged port in the voice VLAN. ACCESS: Supported. TRUNK: Supported. The default VLAN of the port should be UNTAG voice voice VLAN, and the port should belong to the default VLAN. stream GENERAL: Supported. The default VLAN of the port should be voice VLAN and the egress port should be configured as an untagged port of the voice VLAN. Table 12-2 Port voice VLAN mode and voice stream processing mode Note: 1. If the 802.1X authentication and Guest VLAN are enabled on the ingress port which received the tagged voice data stream from the IP phone, please assign different VLAN IDs to the voice VLAN, the port's default VLAN and 802.1X Guest VLAN to guarantee each function's normal operation. 2. If the voice data stream sent from the IP phone is untagged, please configure the ingress port's default VLAN as voice VLAN to implement the Voice VLAN function.  Security Mode of Voice VLAN When voice VLAN is enabled for a port, you can configure its security mode to filter data stream. If security mode is enabled, the port just forwards voice packets, and discards other packets whose 256

the tagged voice data stream from the IP phone, please assign different VLAN IDs to the
voice VLAN, the port’s default VLAN and 802.1X Guest VLAN to guarantee each function’s

2.
If the voice data stream sent from the IP phone is untagged, please configure the ingress
port’s default VLAN as voice VLAN to implement the Voice VLAN function.
