Ontap 9.8 The link aggregation port is down

marcinmf — Wed, 04 Jun 2025 10:02:24 GMT

We have a fresh installation of 9.8P7 in a switchless dual node FAS8020.

The desired network setup that i am trying to create is SVM with ISCSI.

Controller 1

2 ports e1a, e1b > If Group > Vlan 1201 > Logical Interface with ip 10.100.10.1/24

Controller 2

2 ports e1a, e1b > If Group > Vlan 1201 >Logical Interface with ip 10.100.10.2/24

Immediately after creating Link Aggregation Group from giu or cli the ifgroup is down. "The link aggregation group is down"

The individual ports are up.

Because group is down i believe vlan is down , lif is down as well. I tried to add and removed Broadcast domain info from group, bring it up / down it stays down nonmatter what i do.

I can create lifs directly on physical ports then svm can use them and everything is connected, however i rather use interface group.

Here is some cli info:

I would appreciate any pointers.

It’s the switch

make sure the switch port channel is mode ACTIVE

i see people all the time do mode ON which is NOT LACP. The ports are up but the channel is down

also, as a habit, the ports connecting to the Netapp should also have ports fast enabled

That is correct. Switch was not configured. Ports are up now.

Thank you.
