Objects represent reusable information, such as network addresses, individual users and user
groups, and commonly used configuration data. In NSM, objects are shared objects, meaning
they are shared between the global domain and all subdomains. Objects are the building
blocks of the NSM management system.
A module of the NSM User Interface that contains the objects used in your NSM system. An
object is a re-usable, basic NSM building block that contains specific information; you use
objects to create device configurations, policies, and VPNs. All objects are shared, meaning
that they can be shared by all devices and policies in the domain.
The person who installs a configlet using Rapid Deployment.
A dynamic routing protocol intended to operate within a single Autonomous System.
Packet filtering is a router/firewall process that uses access control lists (ACL) to restrict flow
of information based on protocol characteristics such as source/destination IP address,
protocol, or port used. Generally, packet-filtering routers do not track sessions except when
doing NAT (which tracks the session for NAT purposes).
Packet Data Protocol.
A user session on a GPRS network.
Protocol Data Unit.
See Neighbor.
The ping of death is an intentionally oversized or irregular ICMP packet that can trigger a Denial
of Service condition, freezing, or other adverse system reactions. You can configure a security
device to detect and reject oversized or irregular packet sizes.
Public Land Mobile Network. A public network dedicated to the operation of mobile radio
communications.
A non-broadcast network where OSPF treats connections between routers as point-to-point
links. There is no election of a designated router and no LSA generated for the network. A router
in a point-to-multipoint network sends Hello packets to all neighbors with which it can directly
communicate.
Joins two routers over a Wide Area Network (WAN). An example of a point-to-point network
is two security devices connected via an IPSec VPN tunnel. On point-to-point networks, the
OSPF router dynamically detects neighbor routers by sending Hello packets to the multicast
address 224.0.0.5.
