Everything in the Cisco DOCCD says otherwise. It says it's metered,
policed, etc.... I for one would like to know if it works like you say or
if it works like the DOCCD. The DOCCD seems to say that it does not exceed
the priority value when the link is congested. Your statement says
otherwise, unless I'm misunderstanding it. Here's the LLQ section. I
thought the whole purpose of it not to exceed the policer rate was to not
starve the lower queues and let other traffic through???????
