Use this command to determine whether another computer is on the network. Ping provides a synchronous response when initiated from the CLI and web interfaces.



For information about the ping command for IPv6 hosts, see ping ipv6.
  • The default count is 1.
  • The default interval is 3 seconds.
  • The default size is 0 bytes.
Format ping {ip-address| hostname | {ipv6 {interface {unit/slot/port | vlan 1-4093 | loopback loopback-id | network | serviceport | tunnel tunnel-id } link-local-address} | ip6addr | hostname} [count count] [interval 1-60] [size size] [source ip-address | ip6addr | {unit/slot/port | vlan 1-4093 | serviceport | network}] [outgoing-interface {unit/slot/port | vlan 1-4093 | serviceport | network}]
  • Privileged EXEC
  • User EXEC

Using the following options, you can specify the number and size of Echo Requests and the interval between Echo Requests.

Parameter Description
ip-address IPv4 or IPv6 addresses to ping.
count Use the count parameter to specify the number of ping packets (ICMP (Internet Control Message Protocol) Echo requests) that are sent to the destination address specified by the ip-address field. The range for count is 1 to 15 requests.
interval Use the interval parameter to specify the time between Echo Requests, in seconds. Range is 1 to 60 seconds.
size Use the size parameter to specify the size, in bytes, of the payload of the Echo Requests sent. Range is 0 to 65507 bytes.
source Use the source parameter to specify the source IP/IPv6 address or interface to use when sending the Echo requests packets.
hostname Use the hostname parameter to resolve to an IPv4 or IPv6 address. The ipv6 keyword is specified to resolve the hostname to IPv6 address. The IPv4 address is resolved if no keyword is specified.
ipv6 The optional keyword ipv6 can be used before the ipv6-address or hostname argument. Using the ipv6 optional keyword before hostname tries to resolve it directly to the IPv6 address. Also used for pinging a link-local IPv6 address.
interface Use the interface keyword to ping a link-local IPv6 address over an interface.
link-local-address The link-local IPv6 address to ping over an interface.
outgoing-interface Use the outgoing-interface parameter to specify the outgoing interface for multicast IP/IPv6 ping.

The following are examples of the CLI command.
