Buffer Pools - Alcatel-Lucent 7210 SAS M OS Quality Of Service Manual

QoS Overview

Buffer Pools

Buffer pools cannot be created or deleted in the 7210 SAS. The default pools created by the
system are distributed among various ports.
The 7210 SAS M when operating in network mode and access-uplink mode, only supports port
egress buffer pools. The egress buffer pools are distributed as network egress buffer pool and
access egress buffer pools. During system initialization, based on the maximum number of ports to
be supported for access and network, the total buffer is distributed into the access egress buffer
pool and the network egress buffer pool. The distribution of the buffers into access and network
egress pools take care of the buffer requirements at the port level for various queue shaping/
scheduling mechanisms and for various packet sizes varying from 64 bytes to jumbo frames.
