Version 6.8 115 Mediant 500 E-SBC
Parameter Description
Underlying Interface
CLI: underlying-if
[DeviceTable_UnderlyingInterface] Assigns an Ethernet Port Group to the VLAN (mandatory field).
For configuring Ethernet Port Groups, see Configuring Ethernet
Port Groups on page
111 .
Name
CLI: name
[DeviceTable_DeviceName]
Defines a name for the VLAN. This name is used to associate
the VLAN with an IP network interface in the Interface table
('Underlying Device' field - see ''Configuring IP Network
Interfaces'' on page
115 ) and/or with a static route in the Static
Route table ('Device Name' field - see ''Configuring Static IP
Routing'' on page
123 ).
By default, the device automatically assigns a name using the
following syntax: "dev <next available table row index>" (e.g.,
"dev 3").
12.4 Configuring IP Network Interfaces
You can configure a single VoIP network interface for all applications, including OAMP
(management traffic), call control (SIP signaling messages), and media (RTP traffic), or
you can configure multiple logical, IP network interfaces for these applications. You may
need to logically separated network segments for these applications for administration and
security. This can be achieved by employing Layer-2 VLANs and Layer-3 subnets. The
figure below illustrates a typical network architecture where the device is configured with
three network interfaces, each representing the OAMP, call control, and media
applications. The device is connected to a VLAN-aware switch for directing traffic from and
to the device to the three separated Layer-3 broadcast domains according to VLAN tags
(middle pane).
Figure 12-4: Multiple Network Interfaces
The device is shipped with a default OAMP interface. For more information, see ''Default
OAMP IP Address'' on page
27 . The Interface table lets you change this OAMP interface
and configure additional network interfaces for control and media, if necessary. You can
configure up to 12 interfaces, consisting of up to 11 Control and Media interfaces including
a Maintenance interface if your device is deployed in a High Availability (HA) mode, and 1
OAMP interface. Each IP interface is configured with the following:
