www.dell.com | support.dell.com The simple network management protocol (SNMP) traps and OIDs in Table 39-2 provide information about environmental monitoring hardware and hardware components. Table 39-2. SNMP Traps and OIDs OID String Receiving power .1.3.6.1.4.1.6027.3.10.1.2.5.1.6 OID Name chSysPortXfpRecvPower Transmitting power .1.3.6.1.4.1.6027.3.10.1.2.5.1.8 chSysPortXfpTxPower Temperature .1.3.6.1.4.1.6027.3.10.1.2.5.1.7 chSysPortXfpRecvTemp Hardware MIB Buffer Statistics .1.3.6.1.4.1.6027.3.16.1.1.4 fpPacketBufferTable .1.3.6.1.4.1.6027.3.16.1.1.5 fpStatsPerPortTable .1.3.6.1.4.1.6027.3.16.1.1.6 fpStatsPerCOSTable Description OID to display the receiving power of the connected optics. OID to display the transmitting power of the connected optics. OID to display the Temperature of the connected optics. Note: These OIDs are only generated if you enable the CLI enable optic-info-update-interval is enabled command. View the modular packet buffers details per stack unit and the mode of allocation. View the forwarding plane statistics containing the packet buffer usage per port per stack unit. View the forwarding plane statistics containing the packet buffer statistics per COS per port. 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 circuit (ASICs) implement the key functions of queuing, feature lookups, and forwarding lookups in the 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. 10G and 40G interfaces use different FPs. You can tune buffers at three locations (Figure 39-7). 1. CSF - Output queues going from the CSF. 2. FP Uplink-Output queues going from the FP to the CSF IDP links. 3. Front-End Link-Output queues going from the FP to the front-end PHY. 656 | Debugging and Diagnostics
