CoS commit validation is missing for classifier when using code-point-aliases. The user can configure duplicate code-point-aliases and use them in a classifier. This results in a cosd crash. The system can be recovered by correcting the configuration and applying the restart class-of-service command. PR1766873

On all platforms, MAC-IP route deletion and addition are triggered when re-ARP (Address Resolution Protocol) on MH (Multihoming) device fails in the EVPN-MPLS multihoming scenario resulting in traffic drop.PR1691132

Ungraceful removal (OIR) of FPC or an FPC fault might result in PCIE MAJOR alarm PCI Uncorrected error on dev 0000:00:03.0 which does not get cleared. PR1620197

Ipv6 transit traffic statics output is missing. PR1620197

When TCP main and TCP remain attached together on the physical interface, it is observed that improper scheduler MAP gets configured on HQoS physical interface while sched params modification and bind are performed on the same commit. This is a sequence issue from CoSD (Routing Engine) which is not guaranteed on the Packet Forwarding Engine side.PR1664785

HQoS - VoQ statistics issue during scaled configuration with congestion. In scaled HQOS configuration with congestion across all queues due to unavailability of the system level packet buffers, packets are dropped irrespective of the queue priorities. These dropped packets are not accounted as part of queue statistics.PR1674669

In ACX7509, time error spike is seen with PTP long run.PR1697093

Interface command gives truncated outputs, response stuck and statistics not displayed when unrelated FPC restarts.PR1698532

In Junos OS Evolved ACX platforms we can configure only a single same unique MAC system wide in virtual-gateway-v4-mac and one virtual-gateway-v6-mac for any number of logical interfaces. Configuring different MAC values for different logical interfaces is not supported. However, the MAC value configured for v4 and v6 CLI can be the same MAC or different values.

Trigger: In the scaled setup with SRv6 micro SID for L3VPN VRFs (~2K) enabled in a single commit, few initial VRF might experience traffic outage. Workaround: Deactivating and re-activating only the failed VRFs resolves the problem.PR1726481

We might encounter jdhcpd core file during initialization. The core file is rare, and there is no service impact because of this core file (as the process recovers immediately). PR1730717

1. On L3 interface (inet/inet6/mpls), if user configures IEEE802.1p classifier alone, then all the flow (inet/inet6/mpls) is classified. If additional non IEEE802.1p classifier (DSCP/EXP etc.,) is mapped to the same interface, then the unmapped family is not classified and is handled as best effort mode.

2. In L2 interface (ethernet-switching), if user configures IEEE802.1p classifier alone, then all the flow (l2/v4/v6/exp) is classified. If additional non IEEE802.1p classifier (DSCP/EXP etc.,) is mapped to the same interface, then the unmapped family is not classified and is handled as best effort mode. Work around: User has to configure classifiers for all the families to do proper classification.

ACX7509 :: DHCP Daemon not running in the new primary Routing Engine post GRES, all DHCPv4/v6 sessions are lost. PR1740530

On Junos OS Evolved ACX7100 platforms, the Packet Forwarding Engine process crashes when unsupported port speed is configured and MACSec (MAC Security) is enabled on the interface configured with unsupported port speed. Due to this issue, there is complete traffic loss of forwarding traffic till the Packet Forwarding Engine process restarts. PR1755883

The evo-pfemand process is observed to crash on Junos Evolved platforms with LACP configuration. PR1756648

On Junos OS Evolved ACX Series platforms, VRRP(Virtual Router Redundancy Protocol) processes fail if delegate-processing ae-irb is configured.PR1747838

ACX7332: After multiple reboots, GL is stuck and after power cycle seeing picd and vmcore.
