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

  • (Applies to an NFX350 device with MACsec on the layer 2 interfaces) After you reboot an NFX350 device or restart the Packet Forwarding Engines on the device, the MACsec connectivity is not established on some of the links.

    Workaround—Delete the layer 2 interface configuration for the affected links and then reconfigure it. PR1640451
