WLC Best Practice - split LAG?


Reading "Wireless LAN Controller Configuration Best Practices" document from Cisco I see this:

"Do not configure a LAG connection that spans across multiple switches. When you use LAG, it must be with all ports that belong to the same EtherChannel that goes to the same physical switch."

My question: Is it considered good or bad design to split the WLC LAG across multiple physical switches also when using virtual switches like VSS in 6500? Or to connect the LAG to different 3750 stack-members in the same stack?

LAG works best if it goes to one LOGICAL switch.

Re: WLC Best Practice - split LAG?

Does this mean that it will still work if LAG connected to multiple switches?

As leolaohoo wrote, a 3750 stack or 6500 VSS are considered as  one logical switch, and you will not have any problem connect a LAG to  diffrent switches within the stack or VSS.
