[c-nsp] Catalyst 4500/Sup5 - carrier-delay supported?

[Clinton Work]

I'm trying to figure out of the Catalyst 4500s running Sup5 with IOS 
12.2SG support the carrier-delay command. The interface capabilities 
show that the old Catalyst link debounce feature isn't supported on 
WS-X4306 GigE interfaces , however the switch allows you to configure 
carrier-delay.  For example:

conf t
interface g5/5
carrier-delay msec 100
end

According to the 12.2(46)SG configuration guide, you can only configure 
link debounce on 10GE interfaces.   I can't find any references to 
support for carrier-delay.
