Services Applications

  • TWAMP Light IPv4 support (MX Series, PTX Series)—Starting in Junos OS Release 21.1R1, we support the Two-Way Active Measurement Protocol (TWAMP) Light, as defined in Appendix I of RFC 5357. TWAMP Light is a stateless version of TWAMP, where test parameters are predefined instead of negotiated. All test packets received by the server on a test port are reflected back and forgotten right away.

    [See twamp.]

  • Support for inline active flow monitoring (PTX10008 and PTX10016)—Starting in Junos OS Release 21.1R1, we support inline active flow monitoring for the PTX10K-LC1105 line card. Inline active flow monitoring supports version 9 and IPFIX flow collection templates. Both the IPFIX and the version 9 templates are supported for IPv4, IPv6, and MPLS, and use UDP as the transport protocol.
