Slope policy parameters

The elements required to define a slope policy are:

• a unique policy ID

• on 7210 SAS-T, 7210 SAS-Sx/S 1/10GE and 7210 SAS-Sx 10/100GE, only two slopes per queue is available

• the high and low RED slope shapes for the buffer pool: settings for the high-priority and low-priority RED slopes

All slopes are available per queue and the following parameters are configurable for each slope:

• start-avg

• max-avg

• max-prob

• Time average factor (TAF)

A slope policy is defined with generic parameters so that it is not inherently an access or a 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.

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 network buffer pools which do not have another slope policy explicitly assigned.

The following table lists the default values for 7210 SAS-T, 7210 SAS-Sx/S 1/10GE, and 7210 SAS-Sx 10/100GE in network mode.
