VLAN Management
Voice VLAN
• DSCP—Displays DSCP values to be used by the LLDP-MED as a voice network policy.
• Root Switch MAC Address—The MAC address of the Auto Voice VLAN root device that discovers or
is configured with the voice VLAN from which the voice VLAN is learned.
• Switch MAC Address—Base MAC address of the device. If the device's Switch MAC address is the
Root Switch MAC Address, the device is the Auto Voice VLAN root device.
• Voice VLAN ID Change Time—Last time that voice VLAN was updated.
STEP 2
The Voice VLAN Local Table displays voice VLAN configured on the device, as well as any voice VLAN
configuration advertised by directly-connected neighbor devices. It contains the following fields:
• Interface—Displays the interface on which voice VLAN configuration was received or configured. If
N/A appears, the configuration was done on the device itself. If an interface appears, a voice
configuration was received from a neighbor.
• Source MAC Address— MAC address of a UC from which the voice configuration was received.
• Source Type— Type of UC from which voice configuration was received. The following options are
available:
- Default—Default voice VLAN configuration on the device
- Static—User-defined voice VLAN configuration defined on the device.
- CDP—UC that advertised voice VLAN configuration is running CDP.
- LLDP—UC that advertised voice VLAN configuration is running LLDP.
- Voice VLAN ID—The identifier of the advertised or configured voice VLAN
• Voice VLAN ID—The identifier of the current voice VLAN.
• CoS/802.1p—The advertised or configured CoS/802.1p values that are used by the LLDP-MED as a
voice network policy.
• DSCP—The advertised or configured DSCP values that are used by the LLDP-MED as a voice
network policy.
• Best Local Source—Displays whether this voice VLAN was used by the device. The following
options are available:
- Yes—The device uses this voice VLAN to synchronize with other Auto Voice VLAN-enabled
switches. This voice VLAN is the voice VLAN for the network unless a voice VLAN from a higher
priority source is discovered. Only one local source is the best local source.
