 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 source MAC addresses do not match OUI addresses. If security mode is not enabled, the port forwards all the packets. Security Mode Packet Type Processing Mode Enable UNTAG packet When the source MAC address of the packet is the OUI address that can be identified, the packet can be Packet with voice transmitted in the voice VLAN. Otherwise, the packet will VLAN TAG be discarded. Packet with VLAN TAG other The processing mode for the device to deal with the packet is determined by whether the port permits the VLAN or not, independent of voice VLAN security mode. Disable UNTAG packet Do not check the source MAC address of the packet and all Packet with voice the packets can be transmitted in the voice VLAN. VLAN TAG Packet with VLAN TAG other The processing mode for the device to deal with the packet is determined by whether the port permits the VLAN or not, independent of voice VLAN security mode. Table 10-3 Security mode and packets processing mode Note : Don't transmit voice stream together with other business packets in the voice VLAN except for some special requirements. The Voice VLAN function can be implemented on Global Config, Port Config and OUI Config pages. 10.3.1 Rate Limit Rate limit functions to control the ingress/egress traffic rate on each port via configuring the available bandwidth of each port. In this way, the network bandwidth can be reasonably distributed and utilized. Choose the menu QoS→Bandwidth Control→Rate Limit to load the following page. 160
