Sad news everyone - I just labbed this up as well using 12.2(15)T16
code.....NONE of it seems to work as documented.
Indeed the default values are not what is documented....AND - it took me
like 25 flaps before I could get the interface to dampen. The penalty
assigned did not appear to be anything close to 1000 - and the penalty would
decay at a rate much faster than the configured or default Half Life.
I only pray that Cisco grades this feature based on the documentation - and
not on how the feature actually behaves in production.
These are the things that make this journey rather frustrating and at times
- in fact - bordering on ludicrous.
