The Realtime Monitor is a module of NSM User Interface. It contains the Device Monitor, the
VPN Monitor, and the NSRP Monitor.
The number of collisions on the line detected by the Carrier Sense Multiple Access Collision
Detection (CSMA/CD) protocol.
The process of importing a route into the current routing domain from another part of the
network that uses another routing protocol. When this occurs, the current domain has to
translate all the information, particularly known routes, from the other protocol. For example,
if you are on an OSPF network and it connects to a BGP network, the OSPF domain has to
import all the routes from the BGP network to inform all of its devices about how to reach all
the devices on the BGP network. The receipt of all the route information is known as route
redistribution.
A list of routes the current routing domain imported from another routing domain using a
different protocol.
A Remote Settings object defines the DNS and WINS servers that are assigned to L2TP RAS
users after they have connected to the L2TP tunnel.
Report Manager is a module of the NSM User Interface. Use Report Manager to generate and
view reports summarizing log and alarm originating from the managed security devices in your
network. You can use these reports to track and analyze log incidents, network traffic and
potential attacks.
The RPC is a protocol that one program can use to request a service from a program located
in another computer in a network.
Role-based administration enables you to define strategic roles for your administrators and
create domains to organize your network devices. Use role-based administration to create a
security environment that reflects your current offline administrator roles and responsibilities.
BGP provides a technique to block the advertisement of the route somewhere close to the
source until the route becomes stable. This method is called flap damping. Route flap damping
allows routing instability to be contained at an AS border router adjacent to the region where
instability is occurring. The impact of limiting the unnecessary propagation is to maintain
reasonable route change convergence time as a routing topology grows.
Route maps are used with BGP to control and modify routing information and to define the
conditions by which routes are redistributed between routing domains. A route map contains
a list of route map entries, each containing a sequence number and a match and a set value.
The route map entries are evaluated in the order of an incrementing sequence number. Once
an entry returns a matched condition, no further route maps are evaluated. Once a match has
been found, the route map carries out a permit or deny operation for the entry. If the route map
entry is not a match, then the next entry is evaluated for matching criteria.
Route redistribution is the exporting of route rules from one virtual router to another.
