Networking Tools
The
Networking Tools
page provides the possibility to check the Internet connection.
Ping
sends four ICMP (Internet Control Message Protocol) requests with a default size of 64 bytes to the destination (IP address or host name)
specified in the text field
Ping Target
. The response times are logged, and the round trip time (the time required from being sent until being received
again) is measured. The minimum and maximum round trip time and its average as well as the percentage of lost and of received frames results are
displayed in the lower area of the page.
Traceroute
checks the Internet connection by triggering the routers (hops) that are passed to reach the destination specified in the
Traceroute
Target
text field.
Trace routing gives feedback on the routers passed by packets on the way toward the destination and the round trip delay of
packets to these routers.
Attention:
No
Traceroute
is possible if a high priority Firewall has been enabled (see chapter
Firewall and NAT
).
For the purpose of tracerouting, several IP packets are sent out. UDP (User Datagram Protocol) is used to send packets and ICMP (Internet Control
Message Protocol) is used to receive information about the routers. In their headers, the TTL (Time To Live) value increases from 1 to 30. When the
first IP frame is received by the first router, its IP address will be returned in its acknowledgement.
The second frame delivers the IP address of the second
router and so on and so forth. The results of
Traceroute
are
displayed on the lower area of the page.
Ping
Target
requires the destination (IP address or host
name) for the ping request. If
Use ICMP
checkbox is
selected, an ICMP request will be send to the ping destination
(MS Windows standard). Otherwise, if checkbox is not
selected, a UDP request will be send (Linux standard).
The
Ping
button starts pinging the specified ping target.
Traceroute
Target
is used to enter the IP address or host
name of the destination to be trace routed.
The
Traceroute
button is used to process the router
triggering to check the Internet connection.
In the field below these, the output of the Ping or Traceroute
procedure is shown.
Fig. II-58: Networking Tools page
To Check the Internet connection
1.
Specify the destination address for the ICMP request in the
Ping Target
text field.
2.
Press
the
Ping
button to process the ICMP request.
3.
Specify the destination address to trace the route.
4.
Press

SNMP Settings
The
Simple Network Management Protocol
(SNMP) is an application layer protocol that facilitates the exchange of management information
between network devices and is used by network administrators to manage network performance, find and solve network problems, and plan for
network growth.
On Quadro, SNMP agent is running to allow administrators to remotely manage Quadro’s network and the device’s configuration. Remote
administration is being performed by means of special SNMP monitoring programs (SNMP Manager), which can automatically feedback by the
certainly configured actions on some events on the Quadro or remotely modify Quadro’s settings.
SNMP Settings
page is divided into two pages:
Global SNMP Settings
and
SNMP Trap Settings
.
Global SNMP Settings
are used to enable the
SNMP agent on the Quadro, to select the SNMP protocol version for communication with the administrating application and to define the community
for administrating application to connect the Quadro.
Enable SNMP
checkbox is used to enable SNMP agent on the Quadro.
System Location
text field requires optional information to describe the network where SNMP management is performed.
