Mediant 500L MSBR
Parameter Description
Web/EMS: Secondary DNS
CLI: secondary-dns
[InterfaceTable_SecondaryD
NSServerIPAddress]
(Optional) Defines the secondary DNS server's IP address (in
dotted-decimal notation), which is used for translating domain names
into IP addresses for the interface.
By default, no IP address is defined.
Web: Underlying Device
CLI: underlying-dev
[InterfaceTable_UnderlyingDe
vice]
Assigns an Ethernet Device to the IP interface. An Ethernet Device is
a VLAN ID associated with a physical Ethernet port (Ethernet
Group). To configure Ethernet Devices, see Configuring Underlying
Ethernet Devices on page
137.
WAN Interface Name
CLI: bind interface <interface
name> voip
[WanInterfaceName]
Assigns a WAN interface to the VoIP traffic (i.e., SIP signaling and
media / RTP interfaces). The available WAN interface options
depends on the hardware configuration (e.g., Ethernet and SHDSL)
and/or whether VLANs are defined for the WAN interface. If VLANs
are configured, for example, for the Ethernet WAN interface, you can
select the WAN VLAN on which you want to run the SIP signaling
and/or media interfaces.
The WAN interface can be assigned to SIP signaling and media
interfaces in the SIP Interface table (see Configuring SIP Interfaces
on page 283) and Media Realm table (see Configuring Media
Realms on page 275), where the WAN interface is denoted as
"WAN".
Once this association is set, VoIP traffic is sent via the WAN and
incoming traffic is identified as coming from the WAN. The device
also automatically configures the required port forwarding and static
NAT rules.
Notes:
 For this parameter to take effect, a device reset is required.
 If you do not assign the WAN interface to SIP and media
interfaces, then the WAN interface may not be used for VoIP
traffic. In such scenarios, the VoIP traffic can be sent and
received within the LAN, or sent to the WAN via a third-party LAN
router. If a third-party router is used as the interface to the WAN,
then you need to define NAT rules (using the NATTranslation
parameter) to translate the VoIP LAN IP addresses (defined in
the Interface table and associated with SIP and media interfaces)
into global, public IP addresses.
 This parameter is applicable only if the data-routing functionality
is supported (i.e., relevant Software License Key is installed on
the device).
