STP Incompatibility Between Netgear XS708T and MS510TXUP
Hi
I'm encountering a peculiar issue while trying to configure LAG (Link Aggregation Group) in my network, and I'm hoping someone here can help me figure it out.
I have a mix of Netgear switches: an XS708T, an MS510TXUP, and an S3300-28X. Currently, I'm running a stable daisy-chain setup via the SFP+ ports, but I really want to move to LAG for better performance and redundancy.
The problem is that the STP (Spanning Tree Protocol) options are drastically different between the XS708T and MS510TXUP:
XS708T and S3300-28X offer six different STP modes:
Src MAC, VLAN, EType, incoming port
Dest MAC, VLAN, EType, incoming port
Src/Dest MAC, VLAN, EType, incoming port
Src IP and Src TCP/UDP Port fields
Dest IP and Dest TCP/UDP Port fields
Src/Dest IP and TCP/UDP Port fields
MS510TXUP is limited to only two modes:
Src/Dest MAC, incoming port
Src/Dest IP and TCP/UDP Port fields
The strange thing is that LAG works perfectly fine between the XS708T and S3300-28X, but as soon as I involve the MS510TXUP, the entire network freezes. This happens in an environment with no VLANs configured.
Has anyone here encountered similar problems, or do you have any tips on how I can resolve this? I'm wondering:
Is there any way to configure LAG with these different STP options?
Is this perhaps a software limitation of the MS510TXUP, and if so, are there any plans for an update?
Any tips and advice would be greatly appreciated!

These control selections are to select the policies on how the traffic is distributed on the two or more physical links on a LAG. Every chipset vendor and OEM does typically have different sets available - at the end of the day, a switch with a correct configured and working LAG does not care about. Unrelated to STP - however, STP must sometimes be explicitly configured and enabled on the LAG "device".
