General Routing

  • IPv6 precedence classifier, rewrite CLI is not supported for ACX7000 platforms.PR1587002

  • For queues without any guaranteed bandwidth configured, no queue drop counter statistics could be displayed in the case of continuous traffic congestion. This includes those packets getting dropped on queues due to the fact that:

    • Other queue(s) have 100% of bandwidth configured.

    • Other queue(s) are configured as priority queue(s) without any shaper.

    Traffic flow behaviour is as expected per configuration and no impact due to this issue. PR1732194

  • While disabling and enabling all the lanes of 400G optics together, carrier transition count on random lanes might get incremented. There is no functional impact.PR1779602

Routing Protocols

  • Pruned route entries are not programmed in the case of inclusive tunnels without local receivers. Traffic is dropped in the ingress stage in the PE, hence route resolve does not happen. Thus, this multicast route is not maintained in RPD and the Packet Forwarding Engine. PR1742233
