TDynamic Buffer Allocation for an IronStack
9
PowerConnect#qd-buffer 1 2 76 2
Syntax: qd-buffer <DeviceNum> <PortTypeVal> <NumBuffers> <PriorityQueue>
"DeviceNum: 0-x
"PortTypeVal: 1 for 1 Gbps or 2 for 10 Gbps
"NumBuffers: Number of buffers to allocate (minimum 1, maximum 4095)
"PriorityQueue: Designates a specific queue (0 to 7).
Sample Configuration
This sample configuration assumes a four-unit stack with the following topology. Note that there is
no packet processor number 3 or 7, because stack units 2 and 4 are 24-port devices.
Stack unit 1, 48 ports - packet processor numbers 0 and 1
Stack unit 2, 24 ports - packet processor number 2
Stack unit 3, 48 ports - packet processors 4 and 5
Stack unit 4, 24 ports - packet processor number 6
Configuration Command Example
The following commands allocate available buffers to be used by priority 0 queues in the four-unit
stack:
