- Cluster management network
Issue
- Management interface is not reachable after ONTAP Upgrade from 9.1P16 to 9.3P21
- Admin
SVM
has two interfacesmgmt
andintercluster
:Mgmt LIF
is configured with ip address10.0.0.5/24
on porte0M
Intercluster LIF
is configured with ip address172.16.1.8/24
on porte0a
- The client is on the same subnet as the
intercluster LIF
and has IP 172.16.1.5/24 - The only static route configured for the
SVM
is a default route that points to10.0.0.1/24
- The client connects to the
mgmt LIF
(one0M
) that is remote to its subnet, sending a packet to10.1.1.254
- When ONTAP looks up the return route for this traffic, it will note that it has a directly connected route via the port
e0a
on the172.16.1/24 subnet
where the172.16.1.5 (intercluster) LIF
is configured - The return traffic will exit of the node's
e0b
port directly to the client
