Description

Check the reachability of a Segment Routing with IPv6 data plane (SRv6) network.

Options

`host`	IPv6 loopback address or SRv6 Segment Identifier (SID) of the remote system to ping.
count `requests`	(Optional) Number of ping requests to send. The range of values is 1 through 1,000,000. The default value is 5.
detail	(Optional) Include in the output the interface on which the ping reply was received.
instance `routing-instance-name`	(Optional) Name of the routing instance for the ping attempt.
interval `seconds`	(Optional) How often to send ping requests. The range of values, in seconds, is 0 through 2,147,483,647.
logical-system `logical-system-name`	(Optional) Run the command from the specified logical system.
nexthop-address `IPv6-address`	Nexthop IPv6 address of the outgoing interface.
nexthop-interface `interface-name`	Interface name of the outgoing interface.
pattern `hex-string`	(Optional) Specify a hexadecimal fill pattern to include in the ping packet.
sids `value`	Specify the SRv6 SIDs in the SRv6 stack. Add a set of values.
size `bytes`	(Optional) Size of ping request packets. The range of values, in bytes, is 0 through 65,468.
source `source-address`	(Optional) IP address of the outgoing interface. This address is sent in the IP source address field of the ping request. If this option is not specified, the default address is usually the loopback interface.
sweep	(Optional) Automatically determine the size of the maximum transmission unit (MTU).
tos `type-of-service`	Type-of-Service (TOS) value to include in the ping request (IPv6). The range of values is 0 through 255.
ttl `value`	(Optional) Time-to-live (TTL) value to include in the ping request (IPv6). The range of values is 0 through 255.

Output Fields

When you enter this command, you are provided feedback on the status of your request. An exclamation point (!) indicates that an echo reply was received. A period (.) indicates that an echo reply was not received within the timeout period. An x indicates that an echo reply was received with an error code. Packets with an error code are not counted in the received packets count. They are accounted for separately.
