Dynamic Host Configuration Protocol

  • When DHCP trace options are enabled, there is a possibility that jdhcpd could generate a core file. In general, traceoptions should be enabled only for debugging. They should be disabled once debuffing is done.PR1771121

General Routing

  • When ingress policer is configured, to drop ingress traffic, on an interface with upMep the CFM packets generated from the upMep is also be dropped due to the policer. This leads to CFM session going down.PR1754938

  • This is day-1 issue of Juniper server. It exists on all ACX Series platforms where Juniper Networks server runs. Once the asymmetry configured at the backup port, The error propagated to the down stream eventually causes this performance issue of spike.PR1793926

  • SRv6 dynamic sid missing in Packet Forwarding Engine (PFE) and losing 100% VPN traffic after locator address is modified. The issue can be rectified by: Delete the locator/block: commit; re-configure the new locator/block prefix or restart rpd on the primary and backup Routing Engine. In case of ACX Series, please use the restart evo-pfemand on both Routing Engines after the changes to restore consistency.PR1828806

  • Ingress interface-specific IPv6 filters might not work for logical interfaces like aggregated Ethernet/IRB/FTI after events like Packet Forwarding Engine (PFE)/router restart. PR1855552

Multicast

  • On all Junos Evolved platforms, when MVPN (Multicast Virtual Private Network) configured device receives PIM join or IGMP report from the remote peer installs route in next-hop and not in multicast composite next-hop, causing the rpd process to crash. PR1777774

  • When multicast packets transit ACX7100 devices through VXLAN VTEP or core interface without multicast configurations, errors are seen. Suggested to use DDOS configurations provided with the workaround. PR1796501

Precision Time Protocol (PTP)

  • syncE to PTP and syncE to 1pps transient response marginally fails. This happens when the servo gets the initial 100ns jump in one measurement window and the next 100ns in the next measurement window adjusting less initially. PR1611848

Storm Control

  • Storm Control is not working when it is configured on aggregated Ethernet. PR1611848
