Troubleshoot An Under-Voltage Condition; Buffer Tuning - Dell Force10 S4810P Configuration Manual

Troubleshoot an under-voltage condition

To troubleshoot an under-voltage condition, check that the correct number of power supplies are installed
and their Status LEDs are lit.

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 S-Series 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. 1G and
10G interfaces use different FPs.
