-q: Presence of this parameter indicates that only statistics are displayed. By default, all information is displayed.

-r: Records routes. By default, routes are not recorded.

-spacket-size: Specifies length (in bytes) of an ICMP echo request, in the range 20 to 8100. The default value is 56.

-ttimeout: Specifies the timeout value (in milliseconds) of an ICMP echo request, in the range 0 to 65535. It defaults to 2000.

-tostos: Specifies type of service (ToS) of an echo request, in the range 0 to 255. The default value is 0.

-v: Displays non ICMP echo reply received. By default, the system does not display non ICMP packets echo reply.

-vpn-instancevpn-instance-name: Specifies the name of an MPLS VPN instance, which is a string of 1 to 31 characters. It is case sensitive.

remote-system: IP address or host name (a string of 1 to 20 characters) of the destination device.

Description Use the ping command to verify whether the destination device in an IP network is reachable, and to display the related statistics.

Note that:

■You must use the command in the form of ping ip ip instead of ping ip if the destination name is a key word, such as ip.

■Only the directly connected segment address can be pinged if the outgoing interface is specified with the -iargument.

Example # Check whether the device with an IP address of 10.1.1.5 is reachable.
