Ping Test

Use the Ping page to send one or more ping requests from the switch to a specified IP address. You
can use the ping request to check whether the switch can communicate with a particular host on an IP
network. A ping request is an Internet Control Message Protocol (ICMP) echo request packet. The
information you enter on this page is not saved as part of the device configuration.
To display the Ping page, click 

Diagnostics

Ping Test

 in the navigation pane.

Figure 54. Ping Page

 

Table 44. Ping Fields 

Click 

Start

 to ping the specified host and 

Stop

 to end a ping in progress. If you do not click 

Stop

, the

pings continue until the number of pings specified in the Count field has been reached—even if you
navigate way from the Ping page.

Field

Description

IP Address

Specify the IP address you want to reach.

Count

Specify the number of packets to send. The range is 1 to 15 packets and the default is 3 packets.

Interval

Specify the delay between ping packets. The range is from 1 to 60 seconds, and the default is 3 seconds.

Size

Specify the size of the ping packet to be sent. Changing the size allows you to troubleshoot connectivity 

issues with a variety of packet sizes, such as large or very large packets. The range is from 0 to 13000 

bytes, and the default is 0 bytes. 

Status

The current status of the ping test, which can be one of the following:

Not Started—The ping test has not been initiated since viewing the page.

In Progress—The ping test has been initiated and is running.

Stopped—The ping test was interrupted because the user clicked the Stop button.

Done—The test has completed, and information about the test is displayed in the Results area.

Results

The results of the ping test, which includes the following information:

The IP address of the device that was pinged.

The Internet Control Message Protocol (ICMP) number of the packet, starting from 0.

The time it took to receive a reply, in microseconds.

The number of ping packets sent and received, the percent of packets that were lost, and the mini-

mum, average, and maximum round-trip time for the responses in milliseconds.
