I'm putting in some rack time to review certain QoS features. Configuration
is not really a problem. MQC makes this really easy :->
However, I am attempting to observe results, and I am finding that I am
unable to make bad things happen, such as packet drops.
I am pinging from three different routers on a token ring to 3 other routers
via a 64K frame relay. The router that bridges the token ring and frame
networks has the policy configured.
class-map match-all pingr6
match ip precedence 6
class-map match-all pingr7
match ip precedence 7
class-map match-all pingr5
match ip precedence 5

I'm using extended ping, and setting the packet size to 1500, and the ToS
bit to match the values in the class-maps.
Replies appear to be slow, but nothing is being dropped, as I would expect.
Even when I throw in traffic from the border router just to fill up
bandwidth.
Anyone got some thoughts on "proof of concept" for policing?
