Configuring Voice VLAN
Voice VLAN Configuration
Security Mode
For packets that will be forwarded in the voice VLAN, you can configure the
security mode to prevent malicious traffic with faked voice VLAN tag.
For packets to other VLANs, how the switch processes the packets is determined
by whether the selected ports permit the VLAN or not, independent of voice VLAN
security mode.
Disable
: For packets to the voice VLAN, the switch does not check the source
MAC address and the selected ports forward all these packets in the voice VLAN.
The security mode is disabled by default.
Enable
: For packets to the voice VLAN, the selected ports forward only voice
packets whose source MAC addresses match OUI addresses to the voice VLAN,
and discard others.
We recommend that you do not mix voice traffic with data traffic in the voice
VLAN. If necessary, make sure the security mode is disabled.

2.2 Using the CLI
Follow these steps to configure the voice VLAN:
Step 1
configure
Enter global configuration mode.
Step 2
show voice vlan oui
Check whether the OUI address of your voice device is in the OUI table.
Step 3
voice vlan mac-address
mac-addr
mask
mask
[
description
descript
]
If the OUI address of your voice device is not in the OUI table, add the OUI address to the table.
mac-addr
: Enter the OUI address of your device.
mask
: Specify a mask to determine the depth of the OUI that the switch uses to check source
addresses of received packets.
descript:
Give an OUI address description for identification.
Step 4
voice vlan priority
pri
Set the priority for voice packets.
pri:
Specify the priority that will be tagged on voice packets. A bigger value means a higher
priority. The range is 0 to 7; the default is 6. This is an IEEE 802.1p priority, and you can further
configure its schedule mode if needed. For details about schedule mode, please refer to
