LABEL DESCRIPTION
Voice VLAN Global Setup
Voice VLAN Click the second radio button if you want to enable the Voice VLAN feature. Enter a
VLAN ID number that is associated with the Voice VLAN.
Click the Disable radio button if you do not want to enable the Voice VLAN feature.
Priority Select the priority level of the voice traffic from 0 to 7. Default setting is 5. The higher the
numeric value you assign, the higher the priority for this voice traffic.
Apply Click Apply to save your changes to the Switch's run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel
to save your changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this section afresh.
Clear Click Clear to reset the fields to default settings.
Voice VLAN OUI Setup
OUI address Enter the IP phone manufacturer's OUI MAC address. The first 3 bytes is the manufacturer
identifier, the last 3 bytes is a unique station ID.
OUI mask Enter the mask for the specified IP phone manufacturer's OUI MAC address to determine
which bits a packet's MAC address should match.
Enter "f" for each bit of the specified MAC address that the traffic's MAC address should
match. Enter "0" for the bits of the matched traffic's MAC address, which can be of any
hexadecimal characters. For example, if you set the MAC address to 00:13:49:00:00:00
and the mask to ff:ff:ff:00:00:00, a packet with a MAC address of 00:13:49:12:34:56
matches this criteria.
