Cross-stack LAG with new SG350X and SG550X

[Michael Muenz]

Hey guys,

just checked the datasheet of the new 10G SMB switches and there's a little difference in "true stacking" between SG500 and SG550X.

The keyword "LAG" was added, which should mean that we can run LACP over multiple hardware chassis!?

Sadly the administration guide doesn't point to that feature (just LAG).

Can anyone confirm that cross-stack LAG will work with the new SG switches?

Thanks!

SG550X supports link aggregation across multiple units in a stack.

Do you know how you can setup a stack on LAGs? e.g. 4x 10G on Switch 1 and 4x 10G on Switch 2 with the result of 40 GBit inter-stack bandwidth?

Thanks,

Thomas

Thanks to chat support: the answer is too easy:

when you create a stack and add multiple connections / links / cables, the stack will automatically use them in parallel (if they are active).

You can check the link status via cli:
