    Details

      Description

      Noticed following issues with OLT reboot on a successful installed SEBA POD

      • Rebooted OLT after a successful authentication/DHCP and Ping, pings failed after OLT reboot and ONU states was shown as UNKNOWN in GUI
      • ONOS did not show any respective flows for the OLT. UNI ports were missing.
      • But OLT/ONU states were shown fine in the VOLTHA
      • ATT Service instances do not come up until `device-remove` remove is performed in ONOS
      • Noticed that after `device-remove` , flows on the OLT show EAPOL as if authentication needed to be performed for the existing subscriber
