ping

Syntax

ping <IPv4-address | hostname> [ data-fill <pattern> | datagram-size <size> | interval <time> | repetitions <number> | timeout <time> | tos <number> | ip-option (include-timestamp | include-timestamp-and-address |record-route ) | vrf <vrfname>]

Description

Pings the specified IPv4 address or hostname with or without optional parameters.

Command context

Operator (>) or Manager (#)

Parameters

<IPv4-ADDR>

Selects the IPv4 address to ping.

<HOSTNAME>

Selects the hostname to ping. Range: 1-256 characters

data-fill <PATTERN>

Specifies the data pattern in hexadecimal digits to send. A maximum of 16 "pad" bytes can be specified to fill out the ICMP packet. Default: AB

datagram-size <SIZE>

Specifies the ping datagram size. Range: 0-65399, default: 100.

interval <TIME>

Specifies the interval between successive ping requests in seconds. Range: 1-60 seconds, default: 1 second.

repetitions <NUMBER>

Specifies the number of packets to send. Range: 1-10000 packets, default: Five packets.

timeout <TIME>

Specifies the ping timeout in seconds. Range: 1-60 seconds, default: 2 seconds.

tos <NUMBER>

Specifies the IP Type of Service to be used in Ping request. Range: 0-255

ip-option [include-timestamp | include-timestamp-and-address | record-route]

Specifies an IP option (record-route or timestamp option).

include-timestamp

Specifies the intermediate router time stamp.

include-timestamp-and-address

Specifies the intermediate router time stamp and IP address.

record-route

Specifies the intermediate router addresses.

vrf <VRF-NAME>

Specifies the virtual routing and forwarding (VRF) to use. When VRF option is not given, the default VRF is used.

Authority

Operators or Administrators. Users without administrator authority can execute this command from the operator context (>) only.
