Small Business sg550xg 8f8t master / backup / slave behavior
I am facing a strange behavior and i want to know if it's by design or if i misunderstood something.
The unit 1 is stack master.
if second Unit as ID 2 it become Backup.
if second Unit as ID 3 it become Slave.
As a slave i can create a link aggregation with port 1/1 and port 3/1 in an active active configuration (lacp). But if the master crash the slave become unresponsive.
As a backup i can't create a link aggregation with port 1/1 and port 2/1 in an active active configuration (lacp). the port 2/1 act as standby in the LAG. But if the master crash the backup take the master role and network operations continu working.
With a SG500XG 8f8t (installed at another customer) i can have a backup switch with link aggregation active/active lacp.
My name is Rozana and i am an engineer from the SMB team.
I would need more information to understand the origin of the issue ( for example what are the other switches in both stacks) I think it would be best to call our support line and create a support ticket for the SG550 switch. Then we will gather all necessary information, ask you some detailed questions about the issue and properly troubleshoot this issue.
