2 ports down ethernet

Mohi1 — Wed, 04 Jun 2025 09:48:58 GMT

We are encountering two ports down error on a cluster.

there is no business impact, and the alert is there from a long time

we are planning a upgrade, but this needs to get cleared before that

Do you have cables physically plugged into e0j in node 1 and e0f in node 2? I see a SFP in ifconfig from ASUP on node 2. It looks like this isn't physically cabled right.

I just used the node shell "ifconfig -a" output. I don't want to share publicly. This can be resolved by fixing the cabling or reconfiguring the networking ports.

A " ::> system node run -node <nodename> -command ifconfig -vvv " would give you more information as well, about how the LACP config. is being stablished (More info. at How to troubleshoot LACP issues in ONTAP 9.2+ - NetApp Knowledge Base)
