Physical information about the device includes chassis model, power supply, and fan descriptions. This information is often required when troubleshooting.

The following information is displayed:

> Model (chassisModel)

> Serial Number (chassisSerialNumberString)

> Backplane Type (chassisBkplType)

> Major Alarm (chassisMajorAlarm)

> Minor Alarm (chassisMinorAlarm)

> Temperature Alarm (chassisTempAlarm)

> Fan Status (chassisFanStatus)

> Fan Diagnostic Errors (chassisFanTestResultDisplay)

> Traffic Peak % (sysTrafficPeak)

> Traffic Peak Time (sysTrafficPeakTime)

> Default Power Allocation (cpeExtDefaultAllocation)

> Dot1q Tagging (VlanTrunkPortsDot1qTag)

> Mac Reduction Admin Status (sysMacReductionAdminEnable)

> Mac Reduction Oper Status (sysMacReductionOperEnable)

> STP Fast Start BPDU Guard (stpxFastStartBpduGuardEnable)

> STP Fast Start BPDU Filter (stpxFastStartBpduFilterEnable)

### Model (chassisModel)

Manufacturer’s model number for the chassis.

### Serial Number (chassisSerialNumberString)

The chassis serial number.

### Backplane Type (chassisBkplType)

The chassis backplane type.

### Major Alarm (chassisMajorAlarm)

Whether the chassis major alarm is on or off.

### Minor Alarm (chassisMinorAlarm)

Whether the chassis minor alarm is on or off.

### Temperature Alarm (chassisTempAlarm)

Whether the chassis temperature alarm is on or off.

### Fan Status (chassisFanStatus)

Status of the chassis fan. There are three possible values:

> Minor fault or the number 3 indicates a minor problem with the power supply.

> Major fault or the number 4 indicates a major problem with the power supply.

> Other indicates that the status is none of the above.

Note: If the status is not OK, the Fan Errors field gives more information about the power supply failure condition. Possible errors are 12V+ Bad or 12V- Bad.

### Fan Diagnostic Errors (chassisFanTestResultDisplay)

Test result for the chassis fan. A zero indicates that the supply passed all tests. Bits set in the result indicate error conditions. Possible errors are Temp High, Fan1 Bad, or Fan2 Bad.

### Traffic Peak % (sysTrafficPeak)

Highest percentage of traffic relative to a maximum of 100% on the specified device since it was last rebooted.

### Traffic Peak Time (sysTrafficPeakTime)

Date and time that the traffic peak occurred.

### Default Power Allocation (cpeExtDefaultAllocation)

Indicates the default inline power allocation per port. This is a global configuration parameter that applies to all inline power-capable ports in the system.

Note: The system must consider this object and the per-port configuration object, cpeExtPsePortPwrMax, when determining how much power to allocate to a port. The system will use the lesser of the two values.

### Dot1q Tagging (VlanTrunkPortsDot1qTag)

Indicates whether the tagging on all VLANs, including native VLAN for all 802.1q trunks, is enabled.

Note: Valid only for Cat6K.

### Mac Reduction Admin Status (sysMacReductionAdminEnable)

Indicates whether the Mac Reduction feature, which reduces the number of MAC addresses used in bridge identifier, is administratively enabled on the device or not.

Note: Valid only for Cat6K.

### Mac Reduction Oper Status (sysMacReductionOperEnable)

Indicates whether the Mac Reduction feature, which reduces the number of MAC addresses used in bridge identifier, is operationaly enabled on the device or not.

If the value of this object is true(1), the accepted values for dot1dStpPriority in BRIDGE-MIB should be in multiples of 4096 plus the bridge instance ID (such as VlanIndex). Changing this object value may cause the values of dot1dBaseBridgeAddress and dot1dStpPriority, in BRIDGE-MIB, to be changed.

Note: Valid only for Cat6K.

### STP Fast Start BPDU Guard (stpxFastStartBpduGuardEnable)

Indicates whether BPDU Guard for Spanning Tree Port Fast Start feature is enabled or not.

### STP Fast Start BPDU Filter (stpxFastStartBpduFilterEnable)

Indicates whether BPDU Filtering for Spanning Tree Port Fast Start feature is enabled or not.
