Slope Policy Parameters
The elements required to define a slope policy are:
•
•
•
A slope policy is defined with generic parameters so that it is not inherently an access or an
network policy. A slope policy defines access egress buffer management properties when it is
associated with an access port buffer pool and network egress buffer management properties when
it is associated with a network port buffer pool.
Each access egress buffer pool and network egress pool can be associated with one only slope
policy ID.
Slope policy ID default is reserved for the default slope policy. The default policy cannot be
deleted or changed. The default slope policy is implicitly applied to all access and networkbuffer
pools which do not have another slope policy explicitly assigned.

The high and low RED slope shapes for the buffer pool: settings for the high-priority and
low-priority RED slopes.
The high-slope ( for tcp in-profile packets), low-slope (for tcp out-of-profile packets)
and non-tcp slope( for non-tcp packets). All three slopes are on a per port per queue basis.
And configurable parameters on each slope are start-avg, max-avg,max-prob and time-
averaging-factor.
