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 ...
Hi Andrew,
Thanks for getting back to me.
You're right, the example I gave did have both ports on the same switch, I should have given exact info, apologies.
The config we were trying to acheive was:
SAN Controller 1 | Switch Stack
10.192.1.81 | 10.192.1.203
|
e0a <-----------> 2/0/14
vif1< | > LAG1
e0b <-----------> 3/0/37
|
SAN Controller 2 | Switch Stack
10.192.1.82 | 10.192.1.203
|
e0a <-----------> 2/0/16
vif1< | > LAG2
e0b <-----------> 3/0/39
|
And this is what I got working:
SAN Controller 1 | Switch Stack
10.192.1.81 | 10.192.1.203
|
e0a <-----------> 2/0/14
vif1< | > LAG1
e0b <-----------> 2/0/16
|
SAN Controller 2 | Switch Stack
10.192.1.82 | 10.192.1.203
|
e0a <-----------> 3/0/37
vif1< | > LAG2
e0b <-----------> 3/0/39
|
Hope you like my pretty illustration... ;)
Both SAN1 vif1 and SAN2 vif1 are in LACP mode, set to load balance on IP. Mtu's are default (1500). No ACLs, no VLANs.
On the switch stack we had no VLAN's, no ACL's, no subnetting, no QOS. Basically no advanced features.
I had reset the stack to factory defaults and then configured the LAG's and NOTHING else. Everything is in the management VLAN(1). Mtus are default.
With both interfaces on controller 1 or controller 2, connected to different switches, only 1 port comes up. To get it to work, the ONLY config change was to change swith ports 2/0/16 and 2/0/39 on the LAGs and physically, and then both come up as expected. No changes were made on the SAN to get it to work.
I wondered if it was port security or some other config that was causing the problem but I'm a bit of a jack of all trades - master of none!! So I'm not sure.
The firmware version on the switch stack is the most recent - 8.0.3.15. The Netapp FAS2020 is running Ontap 7.3.3.
I've been messing around on creating VLAN's since then but its not saved so tonight, I will reload the stack and then send you the config working and the config not working to see if you spot anything.
I'm not sure how I would get you the config on the Netapp but I'm happy to try if you think it will be helpful?
Can you think of any other possible causes?
Your help is much appreciated.
Cheers,
Pat
