63.7 ping
Command:
ping [[src ] { | host }]
Function:
Issue ICMP request to remote devices, check whether the remote device can be reached by the switch.
Parameters:
<source-address> is the source IP address where the ping command is issued, with IP address in dotted decimal
format. <destination-address> is the target IP address of the ping command, with IP address in dotted decimal
format. > is the target host name of the ping command, which should not exceed 64 characters.
Default:
5 ICMP echo requests will be sent. The default packet size and time out is 56 bytes and 2 seconds.
Command Mode:
Admin mode
Usage Guide:
When the ping command is entered without any parameters, interactive configuration mode will be invoked. And ping
parameters can be entered interactively.
Example:
Example 1: To ping with default parameters.
Switch#ping 10.1.128.160
Type ^c to abort.
Sending 5 56-byte ICMP Echos to 10.1.128.160, timeout is 2 seconds.
...!!
Success rate is 40 percent (2/5), round-trip min/avg/max = 0/0/0 ms
In the example above, the switch is made to ping the device at 10.1.128.160. The command did not receive
ICMP reply packets for the first three ICMP echo requests within default 2 seconds timeout. The ping failed for
the first three tries. However, the last two ping succeeded. So the success rate is 40%. It is denoted on the switch “.”
for ping failure which means unreachable link, while “!” for ping success, which means reachable link.
Example 2: Use ping command with source address configuration, and leave other fields to default.
Switch#ping src 10.1.128.161 10.1.128.160
Type ^c to abort.
Sending 5 56-byte ICMP Echos to 10.1.128.160, using source address 10.1.128.161, timeout is 2 seconds.
