Table 13-1. SNMP Traps and OIDs
Recognize an Overtemperature Condition
An overtemperature condition occurs, for one of two reasons:
• The card is too hot.
• A sensor has malfunctioned.
To discover the cause, inspect cards adjacent to the card reporting the condition.
• If directly adjacent cards are not normal temperature, suspect a genuine overheating condition.
• If directly adjacent cards are normal temperature, suspect a faulty sensor.
When the system detects a genuine over-temperature condition, it powers off the card. To recognize this
condition, look for the system messages shown in Message 3.
To view the programmed alarm thresholds levels, including the shutdown value, use the
show alarms
threshold
command, shown in the following output example.
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

optics.
Note: These OIDs only generate if you enable the
