PING, “Dupe IP Error” is displayed indicating a duplicate IP address is present on the network. If no PING response is received within ten seconds, “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 “No Gateway Found” message indicating either the gateway is not functioning properly or an incorrect gateway IP address was entered. When a gateway is located, a “Gateway Found” message is displayed and the PING test continues as described above. When a PING response is received from another subnet, the MAC address of the Gateway is shown (GW MAC) when the Info key is pressed.
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)
IP LIST SCREEN
When “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 “Waiting” 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 presented.
IP LIST RESPONSE SCREEN
The IP 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 ad- dresses that are found or “No Response” for IP addresses that did not respond within ten seconds. Times that are less than one second are shown in
IP RESPONDER MODE
The Pinger will respond to a PING request that is sent to the unit’s IP address. When the unit is in the LINK Screen showing speed/polarity, a PING to the Pinger IP address presents the PING Received screen.
The Ping Received screen shows the IP and MAC addresses of the PING source. The data packet in the PING request is limited to no more than 128 bytes or else the request will be discarded by the Pinger.
