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.
