GSM7352Sv1 Netapp LACP LAG
Hey, Trying to configure an LACP LAG with a GSM7352S and our Netapp FAS2020 SAN but I can only ever get one port to come up. We have an 8 switch stack (GSM7352S). We're using 2/0/14 and 2/0/16 ...
We've run LAGs to Apple Xserve (LACP), Dell PE2950 running CentOS (static LAGs), Supermicro "whitebox" with a Xeon 5500 series main board running OpenSolaris (LACP), and some old 3Com 100Mbps switches (static LAGs). They're all using 2 port LAGs that go to two different GSM7352Sv1 in the same stack. They all work just fine.
It should work. Maybe the Netapp is using a hinky LACP implementation?
That said, your original post didn't say anything about this being done on multiple switches. All the LAGs you referenced used both ports from the same switch. If you were doing this across multiple switches in your stack, the port numbers in the LAG would be something like 1/0/14 and 2/0/14 not 2/0/14 and 2/0/16
Are you certain you don't have other issues here? Dropping an extra $12K on Cisco gear just to solve this problem seems premature.
I still think you may have another problem affecting one of the ports you tried originally. It could be just a simple thing like one of the ports is configured just a little differently or the second cable is plugged into the wrong port. It could be a misapplied ACL. There are numerous problems it could be, but it's next to impossible to figure out without seeing the actual configuration on both ends.
What firmware version are you running on your switch stack?
