General Routing

  • syncE to PTP and syncE to 1pps noise transfer tests fail for frequencies on ACX7100-32C

    • 0.00781 HZ

    • 0.01563 HZ

    • 0.03125 HZ

    • 0.06156 HZ

    • 0.12313 HZ

    PR1611911

  • On ACX Series routers, 400G DAC flap might be seen after OIR, FPC restart, device reboot, enabling or disabling interface. PR1618488

  • ACX7024: With high scale of L3VPN VRF instances system CPU usage might continue to be high.PR1655310

  • Due to low CPU on ACX7024, aggregated Ethernet interface takes longer time to come up after deactivating or activating in multi-D scale set up.PR1677809

  • When test agents participating to UDP measurement are close by and time is not well synchronised, reporting results is paused due to measured negative one way delay.PR1684358

  • Current DHCP server implementation on ACX7100 uses set access address-assignment pool pool-name family inet network configuration to allocate all possible IP's from the subnet. One possible workaround is to adjust the netmask according to either increase or decrease the pool size. Full functionality of authd is not available on ACX7100 as it is a small-size platform.PR1689194

  • When testing for Class-C performance using channelised 50g interface speed with 100g and 25g as other port, the average cTE marginally exceeds the Class-C mask.PR1695674

  • For ACX platforms, protocol mtu (inet, inet6) need to be configured at the family level otherwise family level mtu is not enabled. For example; set interfaces interface_name unit 0 family inet mtu mtu value. PR1696370

  • On all Junos OS Evolved platforms, when remote side is applied with 2x100G configuration, and the device is configured with 100g (default speed also), the device's link and the first channel on the remote end comes up.PR1699652

  • ACX7024-T-GM: 1PPS, 2Way performance crosses 100 nsec for multi-path scenario in extreme multi-path conditions.PR1707339
