After an upgrade from ONTAP 9.7x or earlier to ONTAP 9.8, you should verify your network configuration. After the upgrade, ONTAP automatically monitors layer 2 reachability.
Use the following command to verify each port has reachability to its expected broadcast domain:
network port reachability show -detail
The command output contains reachability results. Use the following decision tree and table to understand the reachability results (reachability-status) and determine what, if anything, to do next.
reachability-status | Description |
---|---|
ok |
The port has layer 2 reachability to its assigned broadcast domain. |
misconfigured-reachability |
The port does not have layer 2 reachability to its assigned broadcast domain; however, the port does have layer 2 reachability to a different broadcast domain. |
no-reachability |
The port does not have layer 2 reachability to any existing broadcast domain. |
multi-domain-reachability |
The port has layer 2 reachability to its assigned broadcast domain; however, it also has layer 2 reachability to at least one other broadcast domain. |
unknown |
If the reachability-status is "unknown", then wait a few minutes and try the command again. |
After you repair a port, you need to check for and resolve displaced LIFs and VLANs. If the port was part of an interface group, you also need to understand what happened to that interface group. For more information, see Repair port reachability.
