General Routing
-
In ACX7509 devices, after multiple FPC online or offline, FPCs are going to fault state. PR1616227
-
It is non impacting message in journal logs, without any functional impact. PR1647592
-
On ACX7024 ::Pseudo Wire setup and tear down rate might be low, due to system CPU limitation. PR1659593
-
If a FEB goes to fault state due to a power-fault (real or artificially triggered for testing), then the subsequent FEB offline can take a few minutes (instead of completing within a minute for a normal offline). There is no other collateral due to this. A FEB online subsequent to the delayed offline will work normally and the FEB will become fully functional again. PR1671719
EVPN
-
On all Junos OS Evolved platforms that support EVPN-MPLS (Ethernet Virtual Private Networks -Multiprotocol Label Switching) services, during switchover or l2-learning restart, some EVPN next hops are not correctly associated with routing-instance in RE (Routing Engine) impacting the traffic forwarding. PR1633344
-
On performing Graceful Routing Engine swithchover on ACX7509 platform with EVPN services, some logical interfaces are missing. The logical interfaces come up post reboot.PR1646722
Services Applications
-
A Paragon Active Assurance (PAA) Test Agent running on the ACX7100 and ACX7509 might report significant jitter spikes, sometimes exceeding 40ms in latency measurements, even in an idle system. These spikes might originate from the device and do not necessarily represent actual network latency. The data plane forwarding performance is not affected by this issue. PR1680309
User Interface and Configuration
-
The system might ask for your password when you try to save configuration file. PR1665008
