When an IP Address, IP List or IP Range is
selected, pressing the PING function key trans-
mits the PING packet and “Wait” is displayed
until a response is received. A summary of the
PING responses is displayed showing the number of PINGs transmitted and the
number of Good and Bad responses. Pressing the Up/Down cursor key shows,
in numerical order, the results of each PING including the Round Trip Time and if
the received data is identical to the transmitted data (Data:Good) or the data has
been corrupted (Data:Bad).
Pressing the INFO function key displays the MAC address of the PINGed
IP address. If no PING response is received
within specified Timeout time (see Timeout
Setup), “No Response” is displayed. When the
PINGed IP address is in a different subnet than
the Pinger IP address, the unit first attempts to locate the default gateway. If the
gateway does not respond, the Pinger displays a “NOGW” message indicating
either the gateway is not operating properly or an incorrect gateway IP address
was entered. When a PING response is received from another subnet, the MAC
address of the Gateway is shown (GW MAC) by pressing the INFO function key.
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.
lIST RESPONSE ScREEN
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).
RaNGE ScREEN
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.
DHcP ScREEN
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.
