Buffer Tuning

Buffer tuning allows you to modify the way your switch allocates buffers from its available memory and
helps prevent packet drops during a temporary burst of traffic.
The application-specific integrated circuits (ASICs) implement the key functions of queuing, feature
lookups, and forwarding lookups in hardware.
Forwarding processor (FP) ASICs provide Ethernet MAC functions, queueing and buffering, as well as
store feature and forwarding tables for hardware-based lookup and forwarding decisions. The 1G and
10G interfaces use different FPs.
You can tune buffers at three locations.
1. CSF — Output queues going from the CSF.
2. FP Uplink — Output queues going from the FP to the CSF IDP links.
