General Routing

  • On the NFX350, if you change the device operational mode to custom mode, ovs-vswitchd cores might be seen on the device. PR1634245

  • On an NFX250 NextGen device, if you delete a vRR VNF and then add it back, the show virtual-network-functions command might show the vRR liveliness state as down.

    Workaround: Configure dhcp force-discover on the em0 interface of the vRR VNF. PR1648041

High Availability

  • On an NFX350 chassis cluster, when FPC0 (when node0 is primary) or FPC7 (when node1 is primary) is restarted by either using the request chassis fpc slot slot restart node local command or due to dcpfe core files on the primary, it restarts FPC1 or FPC8. This might break the preexisting TCP sessions and fail to restart the TCP sessions. The TCP sessions might require a manual restart. PR1557607

Interfaces

  • On the NFX250, the LACP subsystem does not start automatically when the dc-pfe process is restarted.

    Workaround—Deactivate and then activate the aggregated Ethernet interface. PR1583054
