Additional Features

We've extended support for the following features to these platforms.

• Backup liveness detection on EVPN dual-homed peers (EX9204, EX9208, and EX9214)

  [See Backup Liveness Detection on EVPN Dual Homing, node-detection (EVPN-VXLAN), and bfd-liveness-detection (EVPN Node Detection).]

• EVPN loop detection (EX4100-24MP, EX4100-24P, EX4100-24T, EX4100-48MP, EX4100-48P, EX4100-48T, EX4100-F-12P, EX4100-F-12T, EX4100-F-24P, EX4100-F-24T, EX4100-F-48P, EX4100-F-48T, EX4100-H-12P, EX4100-H-12P-DC, EX4100-H-24F, EX4100-H-24F-DC, EX4100-H-24P, EX4100-H-24P-DC, EX4300-MP, EX4300VC, EX4400-24MP, EX4400-24P, EX4400-24T, EX4400-24X, EX4400-48F, EX4400-48MP, EX4400-48P, EX4400-48T, EX4600-VC, EX4650, and EX4650-48Y-VC)—We’ve added support for monitoring all VLANs on a logical interface with the vlan-id all configuration statement at the [edit protocols loop-detect] hierarchy level. This enhancement detects network loops across multiple VLANs and interfaces, improving network stability and performance.

  The listed devices show the following additional behavioral changes for this feature:

  • The revert-interval configuration is not effective for scale loop-detect sessions, making them non-revertive. You must issue the clear loop-detect enhanced interface command to clear the loop condition.

  • The receive statistics for loop-detect PDUs does not increment for scale loop-detect sessions during a loop condition.

  • Only a 1-second transmit interval is supported for scale loop-detect sessions.

  [See EVPN-VXLAN Lightweight Leaf to Server Loop Detection and loop-detect (EVPN).]

• EVPN-VXLAN to EVPN-VXLAN seamless stitching for EVPN Type 5 routes (EX9204, EX9208, and EX9214).

  [See Understanding EVPN Pure Type 5 Routes.]

• Filter-based forwarding using group-based policy (GBP) tags tags (EX4100-48P, EX4400-48F, EX4650, and QFX5120-48T).

  [See Example: Micro and Macro Segmentation using Group Based Policy in a VXLAN.]

• Support for additional firewall matches (EX4100-24P and EX4400-48F). We've added support for the source-port, destination-port, ip-source-address, ip-destination-address, source-prefix-list, and destination-prefix-list firewall filter match conditions for egress port firewall filters and egress VLAN firewall filters. You must use the egress-l2-extended-match configuration statement to enable these firewall filter match conditions.

  [See egress-l2-extended-match.]

• Supported transceivers, optical interfaces, and DAC cables (EX Series and QFX Series)—Select your product in the Hardware Compatibility Tool 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.

• PoE and PoE++ support (EX4100-H-12MP)—We have added PoE and PoE++ features in EX4100-H-12MP. If the perpetual PoE is enabled, power to the connected power device (PD) remains uninterrupted even when the PSE switch is rebooting. Perpetual PoE and Fast PoE are independent to each other and can co-exist. When the switch goes for power cycle, Fast PoE will be applicable, if enabled. When switch goes for reload through Junos CLI reboot command, Perpetual PoE will be applicable, if enabled.

  [See Understanding PoE on EX Series Switches.]

• AR integrated with OISM in an EVPN-VXLAN ERB fabric (EX4400-24MP, EX4400-24P, EX4400-24T, EX4400-24X, EX4400-48F, EX4400-48MP, EX4400-48MXP, EX4400-48XP, EX4400-48P, and EX4400-48T).

  • We support AR with OISM on these devices only with VLAN-based and VLAN-aware MAC-VRF EVPN instances.

  • You can configure the AR leaf role on these devices when they are also acting as OISM border leaf or server leaf devices.

  • You can configure the standalone AR replicator role on other devices in the EVPN-VXLAN network that support the AR replicator role.
