Select:
Select the desired port for Storm Control configuration. It is
multi-optional.
Port:
Displays the port number of the switch.
Broadcast Rate
Mode:
Select the broadcast rate mode.

: Specify the threshold in kbits per second.
ratio
: Specify the threshold as a percentage of the
bandwidth.
pps
: Specify the threshold in packets per second.
Broadcast:
Enable or disable broadcast control feature for the port.
Mulitcast Rate
Mode:
Select the multicast rate mode.
Multicast:

port. The packet traffic exceeding the bandwidth will be
discarded. Select Disable to disable the multicast control
function for the port.

Voice VLAN
Overview
The voice VLAN feature is used to prioritize the transmission of voice traffic. Voice traffic is
typically more time-sensitive than data traffic, and the voice quality can deteriorate a lot
because of packet loss and delay. To ensure the high voice quality, you can configure the voice
VLAN and set priority for voice traffic.
OUI Address (Organizationally Unique Identifier Address)
The OUI address is used by the switch to determine whether a packet is a voice packet. An OUI
address is the first 24 bits of a MAC address, and is assigned as a unique identifier by IEEE
(Institute of Electrical and Electronics Engineers) to a device vendor. If the source MAC address
of a packet complies with the OUI addresses in the switch, the switch identifies the packet as a
voice packet and prioritizes it in transmission.
