The time after which a port is removed from the Voice VLAN when VoIP traffic is
no longer received on the port. (Range: 10-10,000,000 seconds; Default: 86400
seconds)
Defines a service priority for traffic on the Voice VLAN.
The priority of any received VoIP packet is overwritten with the new priority when
the Voice VLAN feature is active on a port. (Range: 0-7; Default: 7)
The switch provides eight priority queues for each port. For information on how
these queues are used, see the Configuring Egress Port Scheduler section on
page 129.
Specifies if the port will be added to the Voice VLAN. (Default: Disabled)
Disabled - The Voice VLAN feature is disabled on the port. The port will not
detect VoIP traffic or be added to the Voice VLAN.
Auto - The port will be added as a tagged member to the Voice VLAN when VoIP
traffic is detected on the port. You must select a method for detecting VoIP
traffic, either OUI or LLDP (802.1ab).
Note: MSTP must be disabled before the Voice VLAN is enabled (see the
Configuring Global Settings for STA section on page 91), or the Voice VLAN port
mode is set to Auto or Forced. This prevents the spanning tree's ingress filter
from dropping VoIP traffic tagged for the Voice VLAN.
When OUI is selected, be sure to configure the MAC address ranges in the
Telephony OUI list.
The Voice VLAN feature is enabled on the port.
Note: MSTP must be disabled before the Voice VLAN is enabled (see the Config-
uring Global Settings for STA section on page 91), or the Voice VLAN port mode
is set to Auto or Forced. This prevents the spanning tree's ingress filter from drop-
ping VoIP traffic tagged for the Voice VLAN.
Enables security filtering that discards any non-VoIP packets received on the port
that are tagged with the voice VLAN ID.
VoIP traffic is identified by source MAC addresses configured in the Telephony
OUI list, or through LLDP which is used to discover VoIP devices attached to the
switch. Packets received from non-VoIP sources are dropped. (Default: Disabled)
OUI - Traffic from VoIP devices is detected by the Organizationally Unique
Identifier (OUI) of the source MAC address. OUI numbers are assigned to
manufacturers and form the first three octets of a device MAC address. MAC
address OUI numbers must be configured in the Telephony OUI list so that the
switch recognizes the traffic as being from a VoIP device.
LLDP - Uses LLDP (IEEE 802.1ab) to discover VoIP devices attached to the
port. LLDP checks that the telephone bit in the system capability TLV is turned
on. See the Link Layer Discovery Protocol section on page 109 for more
information on LLDP.
Both - Both OUI table lookup and LLDP are used to detect VoIP traffic on a port.
This option only works when the detection mode is set to Auto. LLDP should
also be enabled before setting the discovery protocol to LLDP or Both. Note that
changing the discovery protocol to OUI or LLDP will restart auto detection
process.
