Psiber Data Systems PINGER Manual Do Utilizador

Pressing the DHCP function key in the Link Screen presents the DHCP

Screen and begins the DHCP client-server test.

Note: The MAC Address of the Pinger
Plus may have to be added to the Access
List of the DHCP Server for the Pinger
messages to be accepted - see your
System Administrator for requirements.

The Pinger Plus transmits a “Discover”

message to locate a DHCP server. If no DHCP Server responds to the
message within the DHCP Timeout period (see Timeout Setup), the Pinger
will retransmit the “Discover” message up to three more times. If no DHCP
Server responds after the fourth attempt, “No Response” is displayed.
Pressing the Repeat function key restarts the DHCP discover process. When
a DHCP Server responds to the message, the Pinger displays “Server

Found” the IP Address of the Server and
the IP Address assigned to the Pinger.

Pressing the INFO key displays the

Gateway IP Address and the Subnet
Mask used with the IP Address assigned

by the DHCP Server. Note: If the DHCP Server does not provide the
Gateway IP Address, a 0.0.0.0 IP Address is displayed.

Pressing the PING key while in the DHCP Client mode presents the

PING screen with a “DHCP” message
displayed and the IP Address of the
Gateway. If Gateway information is not
available, the DHCP Server IP Address is
shown.

Pressing the PING key from the IP Ping Screen transmits a PING that

uses the IP Address, Gateway Address and Subnet Mask provided by the
DHCP Server instead of the IP Address, Gateway Address and Subnet Mask
that were previously entered and stored in the Pinger. The Gateway IP
Address is automatically entered as the address to be PINGed (or the DHCP
Server address when Gateway information is not available). Alternatively, a
new IP Address can be entered or  the Up/Down cursor key can be used to
select a previously stored address. Pressing the EXIT key returns the Pinger
back to the LINK Screen and clears the DHCP Server assigned addresses
and mask. Pressing the Setup key also clears the DHCP Server assigned
information and transmits a DHCP release packet to the DHCP server so that
the IP address is available for reassignment.

Note: When the IP address of the device being PINGed is in the same
subnet/VLAN as the IP address of the Pinger, the Subnet Mask can be “ON”
or “OFF” and a Gateway IP address is not required. When the IP address is
in a different subnet/VLAN, the Subnet Mask must be “ON” with the mask
entered and the IP address of the Gateway must be entered. (See Subnet
Mask Setup and Gateway Setup).
CONTINUOUS PING

When the Pinger is configured to PING continuously (See Ping Count

Setup) the letter “C” is displayed to the left of “Name” in the PING Screen.
Pressing the PING function key displays the number of PINGs that have
been sent and the percent of the PINGs with No Response or that had

corrupted data. Pressing the Info function
key displays the PING Address and the
running average of the Round Trip Times
for all PINGs that received a response.

Pressing the Info function key again displays the PING Address and the
count of PINGs that had no response.
LIST SCREEN

When “IP List” is selected and the PING function key is pressed, each

IP address stored in the IP List (see IP List Setup) is PINGed in turn. The

same “Wait” and “No Response”
messages are displayed as described
above. After completing the PING of the
last stored IP address, the IP List
Reponse screen is shown.

The List Response screen shows the results of the PING to each of the

stored IP addresses. The Up/Down cursor key is used to scroll through each IP
address with Round Trip Time, Data status and MAC address presented for IP

addresses that are found or “No Response”
for IP addresses that did not respond within
the Timeout period. Times less than one
second are shown in milli-seconds (ms).

When “Range” is selected, the Range screen is displayed with start and

stop IP addresses. The first three octets of the start and stop address must

be the same and the fourth octet defines
the range from one to a maximum of 255
IP addresses. Pressing the PING function
key PINGs all the addresses in the range
simultaneously. Each PING response can

be viewed by pressing the Up/Down cursor key. Holding the key will cause
the responses to scroll faster.
PING RESPONDER MODE

The Pinger Plus will respond to a PING request that is sent to the unit’s

IP address. When the unit is in the LINK Screen, a PING to the Pinger Plus

IP address presents the PING Received
screen. The Ping Received screen shows
the IP and MAC addresses of the PING
source.
