Using Ping

Ping can be used to test the connection status between two devices. You can ping using the basic default settings, or you can set advanced settings to provide more detailed information.

There are three ways to start the Ping utility:

From the Tools menu—Select Device Utilities, and click Ping. You must then manually enter the IP address.

From the Network Workshop—Select the device, right-click, and click Ping. The IP address of the selected device is automatically entered in the Address field.

From the Device Workshop—Select the System folder, right-click, and click Ping. The IP address of the selected device is automatically entered in the Address field.

Using Basic Ping Settings

To ping an IP address using basic settings:

Start the Ping utility by using one of the methods described above.

The Ping dialog box appears.

Select the Origination point (Figure 12):

To Device—Initiates ping from the computer containing the NMC-RX software you are using to a device. Similar to using the ping command in a DOS window.

Device to IP Address—Initiates ping from an E-series router to another IP address.

Figure 12: Setting the Origination Point

Enter the target address and source address (if applicable).

Click Ping.

The results appear in the dialog box.

NOTE: Depending on the origin selected, different results appear.

When you click Ping again, the previous results are cleared, the command is executed, and the new results are displayed.

Using Advanced Ping Settings

To ping an IP address using advanced settings:

Perform Steps 1-3 in Using Basic Ping Settings.

Click Advanced.

Depending on the Origination type selected, one of the following Advanced Ping Options dialog boxes appears.

Set the Advanced Ping options (Table 66 or Table 67).
 Table 66:  NMC-RX to Device Advanced Ping Parameters 

 Parameter
 Description

 Resolve Addresses

 Select to resolve addresses to host names.


 Set Packet Don't Frag Flag

 Select to send a Do Not Fragment flag in the packet. The packet will not be fragmented by gateways on the route. Use in conjunction with Send Buffer Size option.


 Send Buffer Size (bytes)

 Used to increase or decrease the size of the ICMP packets sent in the ping request

   Minimum: 0
   Maximum: 65500



 Echo Count

 Sends Echo packets specified by count. For example, if the Echo Count is four, four pings will be sent.

   Default: 4



 Type of Service

 Sets the ToS value in the ICMP packet for routers that are set up to treat packets with certain types of service differently than others. ToS is not used very often, and most routers ignore it.


 Time to Live

 Sets the number of hops (routers) that the ping request can traverse before it is discarded. The TTL field in the packet is decremented by one each time it passes through a router. When the number reaches zero, the router discards the packet and sends a TTL Expired ICMP message back.


 Timestamp for Hops

 Specifies the timestamp for the number of hops

   Minimum: 1
   Maximum: 4



 Record Route for Hops

 Records the route of the outgoing packet and the returning packet in the record route field

   Minimum: 1
   Maximum: 9



 Timeout (ms)

 Time ping waits for each reply. 

   NMC-RX to Device uses milliseconds (ms)
   Device to IP Address uses seconds (sec)



 Source Route

   Loose



   Identifies certain milestone routers that must be used in route to the destination address. However, any path can be used to get to these milestone routers.
   When selected, routes packets through the hosts specified in the host list
   Consecutive hosts can be separated by intermediate gateways (loose source routed).
   Maximum allowed by IP is 9



 Source Route

   Strict



   Describes a complete path that must be followed to a destination
   When selected, routes packets through the hosts specified in the host list
   Consecutive hosts cannot be separated by intermediate gateways (strict source routed).
   Maximum allowed by IP is 9

 Parameter
 Description

 Timeout (secs) 

 Time ping waits for each reply in seconds


 Data Size

 Specifies the size of the ICMP payload


 Data Fill

 Specifies the contents of the ICMP payload


 Type of Service

 Sets the ToS value in the ICMP packet for routers that are set up to treat packets with certain types of service differently than others. ToS is not used very often, and most routers ignore it.


 Probe Count

 Number of ICMP packets to send


 Max Rows

 Number of rows displayed



 
(Optional) Enter a host IP address (NMC-RX to Device origination only), and click Add.

The address is added to the IP Address list.

Click OK to close the Advanced Ping dialog box.

Click Ping.

The results appear in the dialog box.

NOTE: Depending on the origin selected, different results appear.

When you click Ping again, the previous results are cleared, the command is executed, and the new results are displayed.
