to activate Auto Voice VLAN:
-
Immediate —Auto Voice VLAN on the device is to be activated and put into operation immediately
if enabled.
-
By External Voice VLAN Trigger —Auto Voice VLAN on the device is activated and put into
operation only if the device detects a device advertising the voice VLAN.
NOTE Manually re-configuring the voice VLAN ID, CoS/802.1p, and/or DSCP from their default values
results in a static voice VLAN, which has higher priority than auto voice VLAN that was learned from
external sources.

Auto Voice VLAN Settings
If Auto Voice VLAN mode is enabled, use the Auto Voice VLAN page to view the relevant global and
interface parameters.
You can also use this page to manually restart Auto Voice VLAN, by clicking Restart Auto Voice VLAN.
After a short delay, this resets the voice VLAN to the default voice VLAN and restarts the Auto Voice VLAN
discovery and synchronization process on all the switches in the LAN that are Auto Voice VLAN enabled.
NOTE This only resets the voice VLAN to the default voice vlan if the Source Type is in the
Inactive state.
To view Auto Voice VLAN parameters:
STEP 1 Click VLAN Management > Voice VLAN > Auto Voice VLAN.
The Operation Status block on this page shows the information about the current voice VLAN and its
source:
• Auto Voice VLAN Status—Displays whether Auto Voice VLAN is enabled.
• Voice VLAN ID—The identifier of the current voice VLAN
• Source Type—Displays the type of source where the voice VLAN is discovered by the root device.
• CoS/802.1p—Displays CoS/802.1p values to be used by the LLDP-MED as a voice network policy.
