Hi Bob,
Please if you do not mind, can you show us an example of doing that, this
seems to be contradictory of what Brian just sent
"it can use more than the specified bandwidth, however traffic in excess of
the rate is not guaranteed low latency. If there is congestion and traffic
exceeds the rate it will be policed."
Thanks
Victor.-

LLQ does not police if there is no congestion. This has been a point of
confusion over the years, and is "unclear" in lots of documentation. You
can easily verify this by configuring a policy that prioritizes ICMP with a
very low bandwidth. Then do an extended ping with large packet size and
zero timeout.
If you do want to police it when not congested, add a police command to the
class.

Subject: LLQ and policing
Hi,
Just trying to nail down an understanding of LLQ.
When you specify the amount of bandwidth that LLQ traffic can have
prioritized, can that class of traffic utilize more available
bandwidth if there is not congestion on the link? In other words is
the prioritized traffic policed to that specified limit?
Thanks
David
