This message indicates that the specied card is not receiving enough power. In response, the system rst shuts down Power over
Ethernet (PoE). If the under-voltage condition persists, line cards are shut down, then the RPMs.
Troubleshoot an Under-Voltage Condition
To troubleshoot an under-voltage condition, check that the correct number of power supplies are installed and their Status light emitting
diodes (LEDs) are lit.
The following table lists information for SNMP traps and OIDs on the environmental monitoring hardware and hardware components.
Table 92. 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 displays 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 displays the transmitting power of the
connected optics.
Temperature
.1.3.6.1.4.1.6027.3.10.1.2.5.1.7 chSysPortXfpRecvTemp OID displays the temperature of the
connected optics.
NOTE: These OIDs only generate if
you enable the enable optic-
info-update-interval is
enabled command.

Buer Tuning
Buer tuning allows you to modify the way your switch allocates buers from its available memory and helps prevent packet drops during a
temporary burst of trac.
The application-specic integrated circuit (ASICs) implement the key functions of queuing, feature lookups, and forwarding lookups in
hardware.
Forwarding processor (FP) ASICs provide Ethernet MAC functions, queueing, and buering, as well as store feature and forwarding tables
for hardware-based lookup and forwarding decisions. 1G and 10G interfaces use dierent FPs.
The following table describes the type and number of ASICs per platform.
