Hi group,
When I configure two options:
shape average 256000 32000
shape peak 256000 32000
I see in the show policy-map int output excessive bits for the average
shaping configuration. However, with average shaping, no traffic
exceeding the cir should be allowed. In the 'increment' column, I do
see with shape average that 32000/8=4000 bytes is entered, whereas for
shape peak it seems to be (Bc+Be)/8.
Can anyone clarify? See config and output below.
