The default WRED network queue profile is WRED profile 57.
The default WRED service ingress queues profile is WRED profile 1.
The default WRED service egress queues profile is WRED profile 33.
Each created queue will have WRED profile applied to it. Either the user configured WRED
profile or, in case that the user does not configure WRED profile, the default policy will be
applied.
The user will not be able to delete or configure profiles 1, 33, 57.
HQoS Granularity Table
The following table shows the extent to which a larger entity is subdivided. For an example:
Network queues CIR and PIR values in the range of 4096Kbps - 16384Kbps have 64Kbps "step"
between each other, or "only" 192 "real" values. If "4159" is entered for CIR, the CLI will "round"
it down to "4096".
