Voice VL AN

Cisco Small Business 200 Series Smart Switch Administration Guide 111

• The Voice VLAN QoS is applied to candidate ports that have joined the

Voice VLAN, and to static ports.

• The voice flow is accepted if the MAC address can be learned by the FDB.

(If there is no free space in FDB, no action occurs).

Configuring Voice VLAN Properties

Use the

Voice VLAN Properties Page

to globally configure the Voice VLAN feature

by configuring the following:

• VLAN ID of the Voice VLAN

• Traffic-class received by the traffic

• Time interval that the port remains in the Voice VLAN after the last VoIP

frame is identified as having an OUI in the table

To enable the feature on a port, it must be globally enabled in the Interface

Settings Page.

To configure Voice VLAN properties:

STEP 1 Click VLAN Management > Voice VLAN > Properties. The

Voice VLAN Properties

Page

opens.

STEP 2 Enter the values for the following fields:

• Voice VLAN Status—Select this field to enable the Voice VLAN feature.

• Voice VLAN ID—Select the VLAN that is to be the Voice VLAN.

• Class of Service—Select to add a CoS level to untagged packets received

on the Voice VLAN. The possible values are 0 to 7, where 7 is the highest

priority. 0 is used as a best-effort, and is invoked automatically when no other

value has been set (default).

• Remark CoS—Select to reassign the CoS level to packets received on the

Voice VLAN. If this option is selected, the outer user priority will be the new

CoS. Otherwise, the outer user priority will be the original CoS, since Trust

mode is used.

• Auto Membership Aging Time—Enter the interval of time after which the

port exits the voice VLAN, if no voice packets are received. The range is from

1 minute to 30 days.
