The Device Manager module in Network and Security Manager (NSM) enables you to
configure the managed Juniper Networks security devices in your network. You can edit
configurations after you add or import a managed device, or create configurations when
you model a device. For details about adding, importing, or modeling a device, see the
Network and Security Manager Administration Guide.
This chapter details the device configuration parameters, and provides configuration
examples when possible. For instructions on configuring specific device settings, see the
Network and Security Manager Online Help.
After you edit or create a configuration for a device, you must update the configuration
on the managed device for your changes to take effect. For details on updating devices,
see the Network and Security Manager Administration Guide.
Use security policies to configure firewall and VPN rules that control traffic on your
network. Use the VPN Manager to configure VPNs.
