transparent-non-std

[rah322]

Can anyone help explain what the "dot1x transparent-non-std enable" configuration command does?  

I'm assuming it's got something to do w/ additional RADIUS request attributes but I haven't a clue as to what non-standard attributes it would apply to.

[10.245.248.2]dot1x transparent-non-std ?
   enable Transport the non-standard attribute enable
