Provisioning the iMG/RG Datafilling the Triple Play Form - Examples

AlliedView NMS Administration Guide
Examples where this type of communication is useful include:
• Sharing a networked printer in a home where there are multiple PCs
• Recording TV broadcast to a DVR and viewing on demand content from the DVR to a PC or STB
• Viewing video, pictures and music libraries stored in a PC on a 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 a single IP interface - This model uses a single upstream VLAN and also a single IP address for
the 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.
Figure 7-88 shows the basic configuration.
FIGURE 7-88 Mediaroom Configuration
The figure shows the separate upstream VLANs model to support the Mediaroom configuration with the iMG. On the
upstream side the VLANs follow the existing model, but on the iMG all LAN ports used for Mediaroom 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 Mediaroom 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 is configured to assign IP addresses to all media devices using
DHCP.
Several configuration fields are required for Mediaroom functionality. These fields are part of the General, Internet and
Video profiles.
