offload-type (TWAMP)

Syntax

Hierarchy Level (Junos OS)

For information about the Junos OS Evolved offload-type statement, see test-session (Junos OS Evolved).

Description

By default for most platforms, timestamps are set in the Packet Forwarding Engine host processor. To account for latency in the communication of probe messages, you can offload timestamping of the probe packets to the Packet Forwarding Engine hardware. This kind of timestamping is called inline timestamping, where the timestamping is done in hardware at the generator or the reflector, right before the packet leaves the device. Support for this offloading and inline timestamping varies by release, platform, and line card support. You cannot configure this statement for cRPD or SRX Firewalls.

Options

inline-timestamp

For those MX line cards that support it, timestamping performed inline in the Packet Forwarding Engine hardware at the generator, and reflection performed in the hardware at the reflector. An MX device often has a mixture of supported and unsupported line cards. When the packets reach the unsupported cards, those cards timestamp on the Packet Forwarding Engine host processor instead.

If si- interfaces are configured on an MX router for TWAMP, then this option is the default for timestamping. To debug the si- interface implementation, you need to configure either the none or the pfe-timestamp option.

none

Timestamping performed on the Routing Engine. Default for cRPD.

pfe-timestamp

(Default for most platforms) Timestamping performed in the Packet Forwarding Engine host processor.
