Click ‘Cancel’ to discard any changes you have entered in the parameter fields.
Note:
Unless a system controller has SNMP installed (for which you need a license), the command is
disabled.
NV9000-SE Utilities will not let you access the SNMP configuration dialog unless both controllers
(if you have a redundant system) are running properly.
Set/Change Virtual IP
A virtual IP address is an artificial IP address that allows your PC and other systems to address
either system controller of a redundant pair using a single IP address.
When you click ‘Set/Change Virtual IP’, the following dialog appears:
The system controller might have up to 6 Ethernet ports, depending in the controller. An NV960
has up to 6; an NV920 has 3.
You can assign a virtual IP address to any of the six possible ports by selecting one of the radio
buttons identified by number and entering an IP address.
Further work must be done within the system controller itself to make the subnet of the actual
port match the subnet of the virtual IP address. That is outside the scope of this manual.
 After specifying a virtual IP address, you must reboot (not restart) both system controllers of
the redundant pair before the virtual IP address can take effect.
Load Snapshot from . . .
Snapshots are primarily a diagnostic tool for use by Grass Valley technical support.
Snapshots are a way of packaging a configuration and the state of the routers at a specific point
in time. When a snapshot is loaded, the system controller restarts with the configuration from
the snapshot and then sets the router crosspoints to the state specified in the snapshot.
The routers defined in the snapshot should match the routers present in the actual system being
controlled when you do the load. A “match” means that router names are identical and with
partition names and sizes being identical.
