SFP monitoring guidelines and default settings

The SFP class groups areas that monitor the physical aspects of SFPs. An SFP class alarm alerts

you to an SFP malfunction fault. SFP performance monitoring is not supported on VE_Ports or

VEX_Ports.

NOTE

SFPs connected to GbE ports are not monitored.

SFP class areas

Table 7 lists Product Name areas in the SFP class and describes each area. Configure the SFP

class using the thConfig command.

NOTE

SFPs connected to GbE ports are not monitored.

SFP monitoring setting guidelines

Use the SFP default settings. The default alarm configuration (log all alarms only to the error log) is

sufficient. It is recommended that you do not allow alerts to go out as SNMP traps. If other Port

class issues are reported, review the error log for any supporting data for SFP issues.

TABLE 7 SFP class areas

Area Description

Temperature Measures the physical temperature of the SFP, in degrees Celsius. A high temperature

indicates that the SFP might be in danger of damage.

Receive power

(RXP)

Measures the amount of incoming laser, in µwatts, to help determine if the SFP is in good

working condition. If the counter often exceeds the threshold, the SFP is deteriorating.

Transmit power

(TXP)

Measures the amount of outgoing laser, in µwatts. Use this to determine the condition of the

SFP. If the counter often exceeds the threshold, the SFP is deteriorating.

Current Measures the amount of supplied current to the SFP transceiver. Current area events

indicate hardware failures.

Voltage Measures the amount of voltage supplied to the SFP. If this value exceeds the threshold, the

SFP is deteriorating.

State Changes Indicates whether the state of the SFP is normal or faulty, on or off. A faulty or off state

means that you must reinsert, turn on, or replace the SFP. Fabric Watch monitors only the

digital diagnostic SFP.

Note: SFPs connected to GbE ports are not monitored.
