Interfaces

  • On the NFX350 device, even though the ethernet cable is physically plugged in and the show interface command displays Front panel LED status as up, the front panel LED is not ON.PR1702799

  • When issuing request support information, there was a syntax error when looking at the nfx-back-plane (was nfx-backplane, instead of nfx-back-plane)

    PR1720228

  • On Junos NFX350 Platforms, if you disable any RJ-45 interface through configuration, auto-negotiation at the MAC (Media Access Control) level on the remaining ports of the group of 4 ports (either 0-3 or 4-7) is disabled, resulting in traffic disruption. The impact isconfined to the group of ports on which the port is disabled and the other group is not affected.

Software Installation and Upgrade

  • Two-step Downgrade (NFX150, NFX250 NextGen, and NFX350)—You cannot downgrade Junos OS Release 23.1R1 directly to certain releases (listed in the Target Release column in Table 1). As a workaround, you can perform downgrade as a two-step activity, in which you downgrade Junos OS Release 23.1R1 first to a corresponding intermediate release (listed in Table 1), and then to the target release.

    Any 22.3x release earlier than 22.3R2. 22.3R2

    • Any 22.2x release earlier than 22.2R3.

    • Any 22.1x release or earlier releases.

VPNs

  • IPSec tunnel is down if IKE external-interface is configured with IPv4 and IPv6 address. As a workaround, specify the local-address inside the ike gateway object if the configured external-interface contains both IPv4 and IPv6 address hosted on it.

VNFs

  • On Junos NFX350 Platforms, in spite of disabling the Auto Negotiation (AN) on the interface through configuration, it stays enabled on the copper ports.This could result in mismatch of AN settings with the remote side configuration and disrupt traffic.
