Uncertain about RLS2.3, but I know RLS2.1 didn't support
LACP, and load balancing was based on VLAN assignment across
member links.

RLS2.4 definitely supports LACP, but load balancing is not
supported. All traffic flows over a single link.
RLS2.5 has a lot of goodies, including flow-based load
balancing (src/dst address hashing). But like RLS2.1, only
up to 4 member links are supported (RLS2.4 supports only 2).
Although I'm currently on RLS2.6, I'm fuzzy on any positive
differences between it and RLS2.5, but this is what I know
is relative to QoS until RLS2.6:
- neither ingress nor egress QoS is supported on the port
-channel interface (future feature).
- QoS needs to be applied on the member links, but...
- only egress QoS is supported on the member links.
Hope this helps.
Cheers,
Mark.
