CLI: Ping Test
The Ping (Packet InterNet Groper) test uses Internet Control Message
Protocol (ICMP) echo requests and ICMP echo replies to determine if another
device is alive. It also measures the amount of time it takes to receive a reply
from the specified destination. The Ping command has several extended
commands that allow advanced checking of destination availability.
Syntax: ping <ip-address | hostname | switch-num> [repetitions <1-10000>]
[timeout <1-60>] [source <ip-address> | <vlan-id>] [data-size <0 - 65471>]
[data-fill <0-1024>]
ping6 <ip-address | hostname | switch-num> [repetitions <1-10000>]
[timeout <1-60>] [source <ip-address> | <vlan-id>] [data-size <0 - 65471>]
[data-fill <0-1024>]
Sends ICMP echo requests to determine if another device is alive.
Note: For information about ping6, see the “IPv6 Configuration
Guide” for your switch.
<ip-address | hostname>
Target IP address or hostname of the destination node being
pinged.
repetitions <1-10000>
Number of ping packets sent to the destination address.
Default: 1
timeout <1-60>
Timeout interval in seconds; the ECHO REPLY must be
received before this time interval expires for the Ping to be
successful.
Default: 5
