AlliedView NMS Administration Guide (Provisioning the iMG/RG)
• Sharing a networked printer in the home where there are multiple PCs
• Recording TV broadcast to DVR and viewing on demand content from DVR to PC or STB
• Viewing video, pictures and music library stored in PC to TV
• Future applications may also include networked appliances (e.g. smart refrigerator, etc.)
The iMG/RG can support three configurations:
1. Separate upstream VLANs - This model uses a separate upstream VLAN for each service and also requires a separate
management VLAN. This is a model already supported by the NMS.
2. Single upstream VLAN with multiple virtual IP interfaces - This model uses one upstream VLAN and separate virtual
interfaces for management, data and voice. A single VLAN simplifies WAN VLAN setup but adds configuration for new
virtual interfaces (Virtual interface configuration support is new in iMGs 3-8).
3. Single upstream VLAN with single IP interface - This model uses a single upstream VLAN and also a single IP address
for iMG. Network configuration is simplified using one VLAN for all services but is less secure because video, data
(Internet) and management traffic are using the same VLAN.
The NMS initially supports Model 1, which is already supported by the NMS. Therefore, the overall steps do not change, but
there are additions to the profiles to provision the iMG.
The following figure shows the basic configuration.
FIGURE 7-87 Media Room Configuration
The figure shows the separate upstream VLANs model to support the media room configuration with the iMG. On the
upstream side the VLANs follow the existing model, but on the iMG all LAN ports used for media room are added to the
local VLAN, with the local network shared with multiple NAT instances that route local traffic to the VLANs configured to
provide service to the connected media room device. In this model the management and voice VLANs are unchanged
because these are not attached to LAN ports. All data and video traffic is routed at the CPE from the local VLAN to upstream
VLAN (no bridged Internet), and the local VLAN will be configured to assign IP addresses to all media devices using
DHCP.
Since the basic provision mechanism is the same as provisioning services without media room, the provisioning flow will
not change but several configuration fields required to support media room are added to General, Internet and Video and pro-
files.
