ping6
Syntax
ping6 {<IPv6-ADDR> | <HOSTNAME>} [data-fill <PATTERN> | datagram-size <SIZE> |
interval <TIME> | repetitions <NUMBER> | timeout <TIME> | vrrp <VRID> | vrf <VRF-NAME>]
Description
Pings the specified IPv6 address or hostname with or without optional parameters. The VRRP option is provided to self-ping the configured link-local address on the VRRP group.
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.
vrrp <VRID>
Specifies the VRRP group ID.
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.
