ping6

Syntax

ping6 {<IPv6-ADDR> | <HOSTNAME>} [data-fill <PATTERN> | datagram-size <SIZE> |
 interval <TIME> | repetitions <NUMBER> | timeout <TIME> | vrf <VRF-NAME>]

Description

Pings the specified IPv6 address or hostname with or without optional parameters.

Command context

Operator (>) or Manager (#)

Parameters

IPv6-ADDR

Selects the IPv6 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.

vrf <VRF-NAME>

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

Authority

Operators or Administrators or local user group members with execution rights for this command. Operators can execute this command from the operator context (>) only.
