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 advantagecom,
Thanks for your response. I had wondered if that was the case without actually knowing spanning-tree would be the cause - must have read it somewhere.
I had the ports admin'd down when I configured the lag thinking that might be enough. I guess spanning tree being disabled on the lag doesn't mean its disabled on the physical ports?
I will disconnect the cables and delete and recreated the LAG before I reconnect the cables but I wonder if I'm configuring the LAG correctly in the first place. Could you tell me roughly how you would configure it?
I'm guessing you..
1. Create the port-channel in global config mode.
load-balance - Would I want to use 5 or 6?
linktrap - I'm assuming this only sends snmp traps for monitoring?
system - Configure port channel system priority (LAG)???
2. Go into physical interface mode for 4/0/1
addport 0/3/1
3. Go into physical interface mode for 4/0/2
addport 0/3/1
Do I need to change anything under lacp in physical interface mode?
actor Configure LACP actor.
admin Configure LACP admin key.
collector Configure LACP collector Max delay time.
partner Configure LACP partner.
Do I need to change anything under the port channel interface mode 0/3/1?
Is there anywhere/anything else I should be configuring??
Thanks again for your help,
Pat
