Max. incomplete TCP/UDP sessions Default 10: Maximum number of incomplete TCP/UDP sessions from the same host
number from same host .
Metric When a router receives a routing update that contains a new or changed destination
network entry, the router adds 1 to the metric value indicated in the update and
enters the network in the routing table.
NAS-ID Defines the request identifier of the Network Access Server.
NAT Configures Address Mapping, virtual server and special applications.
Network Address Destination IP address.
Network Address Enter the IP address of the remote computer for which to set a static route.
Netmask The subnetwork associated with the destination.
This is a template that identifies the address bits in the destination address used for
routing to specific subnets. Each bit that corresponds to a ‘1’ is part of the subnet
mask number; each bit that corresponds to ‘0’ is part of the host number.
Normal Filtering Table Displays the IP address (or an IP address range) filtering table.
Operation data/Defect indication • Noise Margin Maximum upstream and downstream noise margin.
• Attenuation Maximum reduction in the strength of the upstream and
downstream signal.
• Fast Path FEC Correction There are two latency paths that may be used: fast and
interleaved. For either path, a forward error correction
(FEC) scheme is employed to ensure higher data
integrity. For maximum noise immunity, an interleaver
may be used to supplement FEC.
• Interleaved Path FEC to introduce An interleaver is basically a buffer used
a delay, allowing for Correction additional error correction techniques to
handle noise. Interleaving slows the data flow
and may not be optimal for real-time signals
such as video transmission.
Operation Mode Disable: RIP disabled on this interface.
Poison Reverse A method for preventing loops that would cause endless retransmission of data
traffic.
Pre-shared key type Select the key type to be used in the Pre-shared Key.
Pre-shared Key Type in the key here.
Protocol Protocol used for the connection.
Re-Authentication Period Defines a maximum period of time for which the authentication server will
dynamically re-assign a session key to a connected client.
RIP mode Globally enables or disables RIP.
Route Sets the routing parameters and displays the current routing table.
Secret Key The secret key shared between the authentication server and its clients.
Security Log Displays illegal attempts to access your network.

Server Type RADIUS authentication server.
Server IP The IP address of your authentication server.
Server Port The port used for the authentication service.
Session Idle timeout Defines a maximum period of time for which the connection is maintained during
inactivity.
Silent: Listens for route broadcasts and updates its route table.
It does not participate in sending route broadcasts.
SNMP Community string and trap server settings.
