Enables you to send User Datagram Protocol (UDP) or ICMP (Internet Control Message Protocol) echo messages or to a remote IP device.
| count | Specifies the number of ping requests to send. |
| start-size | Specifies the size, in bytes, of the packet to be sent, or the starting size if incremental packets are to be sent. |
| continuous | Specifies that UDP or ICMP echo messages to be sent continuously. This option can be interrupted by pressing [Ctrl] + C. |
| end-size | Specifies an end size for packets to be sent. |
| udp | Specifies that the ping request should use UDP instead of ICMP. |
| dont-fragment | Sets the IP to not fragment the bit. |
| ttl | Sets the TTL value. |
| tos | Sets the TOS value. |
| interval | Sets the time interval between sending out ping requests. |
| vr | Specifies the virtual route to
use for sending out the echo message. If not specified,
VR-Default is used. Note: User-created VRs are supported only on the
platforms listed for this feature in the ExtremeXOS 22.6 Feature License Requirements document.
|
| ipv4 | Specifies IPv4 transport. |
| ipv6 | Specifies IPv6 transport. Note: If you are contacting an IPv6 link local
address, you must specify the VLAN (Virtual LAN)
you are sending the message from: ping ipv6
link-local address
%vlan_name
host
.
|
| host | Specifies a host name or IP address (either v4 or v6). |
| from | Uses the specified source address. If not specified, the address of the transmitting interface is used. |
| with record-route | Sets the traceroute information. |

The ping command is used to test for connectivity to a specific host.
You use the ipv6 variable to ping an IPv6 host by generating an ICMPv6 echo request message and sending the message to the specified address. If you are contacting an IPv6 link local address, you must specify the VLAN you are sending the message from, as shown in the following example (you must include the % sign):
ping ipv6 link-local address %vlan_name host.
The ping command is available for both the user and administrator privilege level.
When the IPv6 host ping fails, the following error message displays:

If you have an asymmetric routing to a specific destination (where the traffic from the source to the destination uses one path, and the return traffic uses another), use this command with option 7, with record-route.
For example:
ping <destination address> with record-route
ping <destination address> from <source-address> with record-route
For more information about this option, see enable ip-option record-route.
The following example enables continuous ICMP echo messages to be sent to a remote host:
ping continuous 123.45.67.8
The following example uses the with record-route option:
ping 10.2.1.1 from 10.2.1.2 with record-route Ping(ICMP) 10.2.1.1: 4 packets, 8 data bytes, interval 1 second(s). 16 bytes from 10.2.1.1: icmp_seq=0 ttl=63 time=10 ms RR: 10.2.1.2 10.2.0.21 10.2.1.1 10.2.1.1 10.2.0.1 10.2.1.2
This command was first available in ExtremeXOS 10.1.
The ipv6 option was added in ExtremeXOS 11.2.
The IPv6 error message was modified in ExtremeXOS 15.2.
