Does anyone know why (Exadata hosts) VPC/LACP becomes "I" when one of Leaf switches gets recycled? It's NOT related to LACP time-out (TAC already verified it).
whenever one of the switches get recycled/disconnected (i.e.: LAB-LEAF8), Port-Channel stays as “Individual” -> NOT_IN_SYNC:
LAB-LEAF7# show lacp interface e1/1
Interface Ethernet1/1 is up
Channel group is 6 port channel is Po6
