If there are a large number of connections of a particular QoS on a particular port, and these connections begin to slow
down and show signs of congestion, use the
set CACEqBwAllocScheme
command to change the CAC policy to
moderate or conservative.
SmartCell ZX # set caceqbwallocscheme

The SmartCell 6A000 performs buffering using a shared-memory architecture. Buffer space is divided into queues for
each QoS. In turn, ports are allocated some portion of each of the QoS queues. This allocation is controlled on a
per-port basis by the
porttrafficcongestion
commands.
Qos is defined on an end-to-end basis in terms of cell loss ratio, cell transfer delay, and cell delay variation.
