PFE crash might be seen and the FPC may remain down on ACX710 platform
Product-Group=junos |
On ACX710 platform, after the PTP(Precision Time Protocol) configuration is removed and the router is rebooted, the PFE might crash and the FPC remains down if PTP traffic is still coming into the router. This issue might also happen when SyncE is configured. This causes the router to crash and not come up. |

BGP multi-pathed traffic might not fully load-balanced for a while after adding a new path for load sharing
Product-Group=junos |
On all Junos platforms with the BGP-ECMP (Equal Cost Multi-Path) scenario, if adding a new path for load sharing, the traffic might not fully load-balanced for a while. The worst-case scenario is much traffic moving to the new path and lead to a link oversubscription. |

[chassisd] [troubleshooting_fru] MX2020 :: Omni MX2K-UNIVERSAL-HV-PSM - PSM firmware upgrade should not allow multiple PSM upgrade in parallel to avoid the firmware corruption and support mutliple firmwares for different Hw Revs
Product-Group=junos |
Running parallel multiple firmware upgrades on the PSMs can result in firmware corruption. This change does not allow to launch a upgrade process when another instance is already running |

Traffic might be affected on QFX10002/QFX10008/QFX10016 platform
Product-Group=junos |
On QFX10002/QFX10008/QFX10016, on the interfaces which map to h/w stream 0, if enhanced transmission selection (ETS), which in JunOS implementation is Hierarchical port scheduling configurations, change while high rate traffic is flowing, the chip might be wedged, thus no traffic flow is seen. Hierarchical port scheduling is the Junos OS implementation of enhanced transmission selection (ETS), as described in IEEE 802.1Qaz. |

The MACSec session might fail to be established if 256-bit cipher suite is configured for MACsec connectivity association being assigned to a logical interface
Product-Group=junos |
On MX platforms except MPC10E/11E, if 256-bit cipher suite (i.e. gcm-aes-256 and gcm-aes-xpn-256) is configured for MACsec connectivity association (CA) and the CA is assigned to a logical interface (IFL), the current MACsec hashing algorithm will use the first 128-bit out of the 256-bit key to calculate the hash value. This might not be compatible with other vendors and even MPC10E/11E on MX. The MACsec session will not be established when interoperating with incompatible device. This PR changed the implementation of MACSec hashing algorithm to resolve the compatibility issue with other vendors and MPC10E/11E on MX. The following CLI knob has been added to provide the backward compatibility with previous Junos versions which use 128-bit hash key implementation.

The multicast traffic might be dropped due to hash mismatch when there are AE and ECMP links involved in multicast tree
Product-Group=junos |
On MX platforms with MPC10 or MPC11 line cards, the multicast traffic over an AE or ECMP interface may be dropped because the hash calculation on the egress line card could be different than on the ingress line card. This could happen if the encapsulation on the egress interface changes a field in the packet that is used in the hash calculation. |
