LACP load balance on 8600

[wmil1105]

Can you configure load balance on LACP links to use IP instead of mac address

For Link aggregation path selection, the 8600 does load distribution for a given packet path based on s sourceXOR/dest IP address hash if its a routed frame. If its straight bridge/switched frame, then the IP is never seen, and used just the MAC address with the same equivalent algorithm (sourceXOR/dest MAC address hash).

Remember, the 8600 is a Layer 3 switch, and as such, can process Layer 2 or Layer 3 with equivalent speeds.

This has changed slightly on the R-modules, such that a new hardware-assisted hash mechanism is added to the source and destination MAC/IP addresses for better distribution.

So, the simple answer is that its already doing that for routed frames, its not for bridged frames.

In order to see which link is being used:
config sys set hash-calc getmltindex traffic-type

I hope this helps.
