Additional Features

We have extended support for the following features to these platforms.

• RPM and TWAMP support (EX4100, EX4400, and EX4650 switches). Starting in Junos OS Release 24.2R1, these EX Series switches fully support RPM and Two-Way Active Measurement Protocol (TWAMP):

  • You can configure RPM probe generation, reception, and reflection and enable timestamps on RPM probe messages.

  • You can also use RPM probes to detect link status and to change the preferred-route state on the basis of the probe results. RPM-tracked routes can be IPv4 or IPv6, and support up to 16 next hops for each IPv4 or IPv6 RPM-tracked static route. You can configure route preference and tag values for each IPv4 or IPv6 destination prefix.

  • You can also configure RPM services to automatically determine whether a path exists between a host device and its configured BGP neighbors. You can view the results of the discovery using an SNMP client. The results are stored in pingResultsTable, jnxPingResultsTable, jnxPingProbeHistoryTable, and pingProbeHistoryTable.

  • For TWAMP, we support IPv4 and IPv6 (including link-local addresses) traffic for control sessions and test sessions.

  • For TWAMP Light, we support IPv4 and IPv6 traffic, including IPv6 link-local addressing.

• Seamless EVPN-VXLAN stitching (EX4100-48MP, EX4400-24MP, EX4400-24P, EX4400-24T, EX4400-24X, EX4400-48F, EX4400-48MP, EX4400-48P, EX4400-48T). We support the seamless stitching of unicast and broadcast, unknown unicast, and multicast (BUM) routes in an interconnected Ethernet VPN–Virtual Extensible LAN (EVPN-VXLAN) environment.

• Supported transceivers, optical interfaces, and DAC cables Select your product in the Hardware Compatibility Tool (https://apps.juniper.net/hct/product/) to view supported transceivers, optical interfaces, and direct attach copper (DAC) cables for your platform or interface module. We update the HCT and provide the first supported release information when the optic becomes available.
