The shutdown of the cascade port might lead to the invalidation of the MPC linecard

In Fusion scenario, on the MPC2E/3E NG HQoS or MPC5E 3D Q linecard, if the cascade port is down (e.g., disabled, deactivated), all the interfaces of the linecard might be unusable.

On PTX10001 and ACX6360 - 100G-LR4 optics and 100G-ER4 optics are not supported

PTX10001 and ACX6360 : 100G LR4 and100G ER4 optics are not yet supported. Please use 100G SR10 optics.

Image installation on SD fails with error " Unable to read reply from software add command to re1; error 1"

Upgrading satellite devices (SDs) with "upgrade-groups" option may fail if any of the SD already has that SNOS software version.

EDVT-GI-MIC2 : "Interfaces not coming up for bidirection module SFP-100BASE-BX10-U & SFP-100BASE-BX10-D"

SFP-100BASE-BX10-U & SFP-100BASE-BX10-D are not supported on 20x1Ge/2x10Ge MACsec MIC due to a Microsemi PHY limitation.

Traffic might get into blackhole when CoS configuration is changed on a PS interface

In CoS scenario, if PS interface uses RLT as PS anchor, all traffic might be dropped on PS interface when deactivating or activating rewrite rules.

vSRX3.0 AppQos Functionality

On vSRX3.0, when using the .vmdk image to install, the AppQos feature may have unpredictable behaviour and srxpfe might core.

SSH is not working if [edit system services ssh hostkey-algorithms] is set or in FIPS mode

When setting the [system services ssh hostkey-algorithm] hierarchy or in FIPS mode, ssh/scp stops working due to faulty entries being inserted into ssh_config.

Flows are getting exported before the expire of the configured active timeout value

The export of the Jflow records is seen at the collector before the expire of the configured active timeout value. This export result might not be the expected.

GMIC2: Input framing errors

In rare situations at heavy traffic loads, input frame check sequence counter may get incremented.

Regression Issue: IPv4 and IPv6 VIP Routes are not withdrawn after AE+VLAN with IRB FLAP

When an interface flapped, VIP routes are not withdrawn during the period of interface flaps, causing packets lost on the AE+VLAN interface.

QFX5K EVPN/VXLAN: Failed to forward the Ipv6 NS packet from remote VTEP to localhost

When clear IPv6 neighbors command is done on L3-GW box, IPv6 ND is not getting resolved on for hosts connected peer L2-GW box. This is because IPv6 NS packets coming on network interface over vtep on QFX5K acting as L2-GW is dropped and not forwarded to access network hosts. Workaround to overcome this issue is to configure no-arp-suppression on QFX5K L2-GW box.

MF classifier: Loss-priority "high" action result in all packets dropped.

Customers should avoid "loss-priority high" action in the firewall filters (MF classifiers).
