a)
The target box shows all zeros, which means that any packet destined to the subnets
shown here causes the VMS to set up a mesh connection.
b) Enter a Label that is easy to remember, such as the name of the target remote (e.g.,
Remote 2 ).
c) Enter the network Address for the remote subnet.
d)
Enter the subnet
Mask
.
e) Click [Add] . The network Address and subnet Mask appear in the Destinations window.
3. Add CDD-880 Expansion Units to Antenna View . To set up a mesh, the VMS must have
available CDD-880 Expansion Units at the target remote site. Remote site mesh units must
be dropped on the antenna and made available as shown here:
Note that this is the antenna view for R2 (Remote 2) and Demodulator #1 of this remote
site’s CDD-880 Expansion Unit is already involved in a mesh with R1 (Remote 1).
4. Define your filtering rules. The VMS dynamically enters filters at the Hub demodulator(s)
when it sets up a mesh. It does this to prevent loops and duplicate packets on the network.
Filters are also a function of the mesh location at the remote site. The CDD-880 HTTP
Interface Configuration | Network | Routing page ( Figure F-3 ) defaults the Mesh Location
to
Hub
.
To ensure proper operation and to prevent network loops, you MUST make
sure that each remote site CDD-880 Expansion Unit has its Mesh Location set to
Remote. The inset in Figure F-3 shows such a Mesh Location setting.
See Sect. 6.3.3.3.1 Configuration | Network | Routing in Chapter 6. ETHERNET-
BASED REMOTE PRODUCT MANAGEMENT in this manual for details about using
this interface.
