[c-nsp] broadcast storm control - linked to int or negotiated speed?

[Christian MacNevin]

Hello,
In 12.2SX, is storm control (as a percentage) definitely linked to the
negotiated speed/duplex of the port? Or is it based on the
hardware capability of the port? ie: will 15% on a gig port limit to 150Mb
regardless of negotiated speed? Or will it adjust to 15Mb
for 100meg negotiated host?
Cheers
Christian.
