The ping command enables you to send ICMP echo messages to a remote IP device.
The ping command is available for both the user and administrator privilege levels.
ping {vr vr-name} {continuous|count|dont-fragment|interval|start-size|tos|ttl|udp} {mac|mpls|ipv4|ipv6} {from|with}
| Parameter | Description |
|---|---|
| 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 are 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. |
| vrid | Specifies the virtual router name 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
Switch Engine v33.1.1 Licensing Guide
document.
|
| ipv4 |
Specifies IPv4 transport. |
| ipv6 | Specifies IPv6 transport. Note: If you are contacting an IPv6 link local address, you must
specify the VLAN 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. |
If a ping request fails, the switch stops sending the request after three attempts. Press [Ctrl] + [C] to interrupt a ping request earlier. The statistics are tabulated after the ping is interrupted or stops.
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 that 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
