Table 1: show chassis afeb

Field Name

Field Description

State

State of the compact Forwarding Engine Board:

  • Offline—FEB is powered down.

  • Online—FEB is operational and running.

  • Check—FEB is in alarmed state because of the following reasons:

    • Hardware error.

    • PFE is unable to boot.

Temperature

Temperature of the air passing by the FEB, in degrees Celsius or in both degrees Celsius and degrees Fahrenheit.

CPU Utilization

Total percentage of CPU being used.

Interrupt Utilization

Of the total CPU being used by the FEB processor, the percentage being used for interrupts.

Heap Utilization

Percentage of heap space (dynamic memory) being used by the FEB processor. If this number exceeds 80 percent, you might experience a software problem (memory leak).

Buffer Utilization

Percentage of buffer space being used by the FEB processor for buffering internal messages.

Total CPU DRAM

Total DRAM, in megabytes, available to the FEB processor.

Start time

Time when the Routing Engine detected that the FEB was running.

Uptime

How long the Routing Engine has been connected to the FEB and, therefore, how long the compact Forwarding Engine Board has been up and running.
