Table 59. SNMP Traps and OIDs
OID String OID Name Description
Receiving power
.1.3.6.1.4.1.6027.3.10.1.2.5.1.6 chSysPortXfpRecvPower OID to display the receiving
power of the connected optics.
Transmitting power
.1.3.6.1.4.1.6027.3.10.1.2.5.1.8 chSysPortXfpTxPower OID to display the transmitting
power of the connected optics.
Temperature
.1.3.6.1.4.1.6027.3.10.1.2.5.1.7 chSysPortXfpRecvTemp OID to display the Temperature
of the connected optics.
NOTE: These OIDs are only
generated if you enable the
enable optic-info-
update-interval
command.
Hardware MIB Buffer Statistics
.1.3.6.1.4.1.6027.3.16.1.1.4 fpPacketBufferTable View the modular packet buffers
details per stack unit and the
mode of allocation.
.1.3.6.1.4.1.6027.3.16.1.1.5 fpStatsPerPortTable View the forwarding plane
statistics containing the packet
buffer usage per port per stack
unit.
.1.3.6.1.4.1.6027.3.16.1.1.6 fpStatsPerCOSTable 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 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.
