Troubleshooting IPC on OS-6/7/8XXX Series of Switches Troubleshooting the Switch System

LocalPool: Full size is 64, remaining: 64
In socket queues: 0 Not queued: 0:
In DMA queues: 0
Each type of pool has the following listed in the command output:
• Maximum size of buffers available
• Currently available buffers
• Socket Queues being used
• Not Queued in pool
• Direct Memory Access Queues
Currently available buffers should always be around the maximum available in normal operation. In some
scenarios, it might happen that the remaining pools are decrementing at a fast rate and are never freeing up
the buffers. This can lead to problem with IPC.
Iterative use of the command will help to identify the situation.
An example is as follows:
Working: [Kernel]->ipc_pools
UrgentPool: Full size is 1024, remaining: 1024
In socket queues: 0 Not queued: 0:
In DMA queues: 0
ControlPool: Full size is 5096, remaining: 5062
In socket queues: 4 Not queued: 20:
In DMA queues: 10
NormalPool: Full size is 2024, remaining: 2022
In socket queues: 0 Not queued: 2:
In DMA queues: 0
JumboPool: Full size is 256, remaining: 255
In socket queues: 1 Not queued: 0:
In DMA queues: 0
