GSM7352S LACP LAGs
Hi there. Im having a small config issue witha GSM7352, i have created 2 LAG's both with 2 port members. Servers are setup for teaming through server 2012. When i try to enable LACP on the sw...
Since you failed to provide a good amount of details in your question.. Here is some details to help you out.
GSM7352S for LAG support LACP with default hash as L3+L4 (IP and port) as the default setting which is preferred between switches. If you have 2012 server and not R2, then I suggest you either stick to switch independent mode with HyperV port setting. If you want to be switch dependent.. then I suggest
Server 2012
LACP + Address Hash + none for standby.
Switch
LACP + L2 (Src/dst mac) hash + Static disabled
For Server 2012 R2
LACP + Address Hash + none for standby
Switch
LACP + L3/L4 (Src/dst ip and port) hash + Static disabled.
Use powershell to verify the hash perference on server 2012 is TCP port or IP.
There is plenty of resource on this... already if you search since none of above is preferred method as it depends on what you gonna use the server for.. if you gonna do a lot of VM ports on 2012 R2 then switch independent with HyperV port is preferred based on benefits... but again you need to figure out what you are trying to gain from it.
ok, my steps were to create a lag, add my 2 ports into it, static disabled, connected my server via 2 ports set as static teaming.
when i try to enable LACP on the server i loose connectivity.
on the switch i have noticed under port configuration i can enable or disable lacp, when i try to do either i get an error.
Error - Failed to set LACP to enable.

im running 2 servers, both 2012 r2 running hyper-v role.
they are setup both with intel pro dual port server adapters, both servers have have a 2 port team setup LACP + HyperV port.
this worked fine on the GS724T i pulled out earlier today, since putting the GSM7352 in i cannot get connectivity to the servers while they are set to LACP.
Sorted it thanks, it was all down to the hash and the PVID of the LAG.
