General Routing

  • On the ACX7100-48L platform running Junos OS Evolved, you cannot clear or reset the disk option specified in the scheduled request node reboot command. The node reboots with the disk option last specified. PR1517596

  • Error messages are observed while accessing the supercon scratch pad registers on bootup and there is no functional impact. PR1594136

  • With IGMPv3 reports received at a higher rate more than 1600 pps, packets are dropped due to control plane rate limit. Therefore, it is not possible to form 2,56,000 IGMP groups. Need to tweak DDOS configuration for reaching 2,56,000 IGMP groups. PR1599998

  • In scaled environment, the interfaces do not come up during FEB offline - online since the Packet Forwarding Engine state does not transition to the online state though FEB has transitions to the online state. PR1601158

  • PTP to PTP noise transfer fails for frequencies 1. 0.03125 HZ 2. 0.123125 HZ. PR1608786

  • The syncE to PTP and syncE to 1pps noise transfer tests fails for frequencies 1. 0.00781 HZ 2. 0.01563 HZ 3. 0.03125 HZ 4. 0.06156 HZ 5. 0.12313 HZ.PR1608866

  • The syncE to PTP and syncE to 1pps transient response marginally fails. This happens when the servo gets the initial 100 nano seconds jump in one measurement window and the next 100 nano seconds in the next measurement window adjusting less initially. PR1608934

  • A restart of DHCP takes more time because of the internal issues with the SIGTERM event. PR1610229

  • PTP to PTP noise transfer fails for frequency 0.03125 HZ. PR1611838

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

  • Default DSCP IPv6 classification might not work in ACX7100 platform. PR1614249

  • Testing G.8275.1 performance with a mix of FEC modes might result in performance that is just outside class C, but still meets class B. Some variability is seen on each reboot. PR1623957
