This is a last resort mechanism intended to prevent a manual power cycle.Buffer tuningBuffer Tuning allows you to modify the way your switch allocates buffers from its available memory, andhelps prevent packet drops during a temporary burst of traffic.The S-Series ASICs implement the key functions of queuing, feature lookups, and forwarding lookups inhardware.• Forwarding Processor (FP) ASICs provide Ethernet MAC functions, queueing and buffering, as wellas store feature and forwarding tables for hardware-based lookup and forwarding decisions. 1G and10G interfaces use different FPs.Table 62-1 describes the type and number of ASICs per platform.You can tune buffers at three locations, as shown in Figure 62-6.Note: Non-management member units do not support this functionality.Command Descriptionhardware watchdog Enable the hardware watchdog mechanism.Table 62-1.
