Interfaces and Chassis

  • On ACX Series router, when link-speed is configured explicitly, aggregate interface goes down permanently after reboot. PR1022248

  • In a normal software MAC learning mode, when incremental MAC traffic of range higher than the profile is received, then after feb restart the MAC entries is not seen in the software table, although present in the hardware table. As a workaround, in the hardware MAC learning mode, delete the routing instance and reconfigure it again to make the MAC entries seen in the software table. In the software MAC learning mode, deactivate the routing instance, clear the pending entries or allow the pending entries to be aged out and then activate the routing instance to solve this issue.

  • On ACX Series PE routers with Layer 3 VPN configured, when running traceroute on ingress PE to CE, only P hop and CE are displayed. The PE information is not displayed. This is a hardware limitation and a workaround is not available.PR1313013
