Grass Valley SiteConfig v.2.1 - Manual (Page 37)

The term "unmanaged network" refers to a network that is administered by an external entity such
as DNS\DHCP or prebuilt hosts files. If a system manages IP addresses using an external entity,
you can create an unmanaged network in SiteConfig to indicate that one or more devices you add
to SiteConfig connects to to the unmanaged network. When configuring network interfaces on
discovered devices, you can specify the interface(s) that connect to an unmanaged network.
SiteConfig can toggle a network connection on a device. SiteConfig can assign the network connection
to use DHCP managed addressing if you specify that the connection/interface connects to a defined
unmanaged network. Or SiteConfig can assign the network connection to use static IP addresses
specified by a managed network you define in SiteConfig.
If there are third party devices that provide name/IP resolution by using a prebuilt hosts file, you
can create an unmanaged network and supply a hosts file to SiteConfig. SiteConfig can then merge
the contents of this hosts file into the hosts file that SiteConfig maintains.
Types of networks
SiteConfig categorizes networks based on the following attributes:
• Data link layer protocol - You can specify whether a network uses Ethernet or Fibre Channel
• Usage - Specify what the network is used for, such as storage networking, control, or streaming
• Redundancy - Specify whether a particular network is the primary or backup path for a network
connection. Some devices might have dual paths in the networking infrastructure to support fault
tolerance by connecting one network interface to the primary path or network and another interface
to the backup network. You can then use SiteConfig to specify which network interface on a
device connects to the primary network and which one connects to the backup network and if it
is a managed network, SiteConfig can configure an appropriate static IP address from the choice
made.
Rules for networks
When adding networks to sites, you are indicating that all devices under that site can connect to the
network. If you edit the network interfaces of any device that you add to that site, SiteConfig shows
you only the networks that are within "scope", which are networks defined in each immediate site
parent going up the hierarchy to the System node.

Network considerations and constraints
• Do not use any 10.1.0.n IP addresses. These are used by the K2 RAID (NEC Condor) maintenance
port and must be reserved for that purpose. If these addresses are otherwise used, maintenance
port communication errors occur.
Creating or modifying a network
1. In the Network Configuration | Networks tree view, select a System node or a Site node.
The networks under that node are displayed in the list view.
