Table 64: show chassis feb

Field Name

Field Description

State

State of the FEB:

  • Offline—FEB is powered down.
  • Online—FEB is operational and running.
  • Check—FEB is in alarmed state where the Switch Interface Board (SIB) plane is partially operational for the following reasons:
    • FEB is not inserted properly.
    • Two or more links between the FEB and Packet Forwarding Engine fail.

Temp (C) or Intake temperature

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

CPU Utilization (%)

Percentage of CPU being used:

  • Total—Total percentage of CPU being used by the FEB processor.
  • Interrupt—Of the total CPU being used by the FEB processor, the percentage being used for interrupts.

Memory DRAM (MB)

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

Utilization (%)

Percentage of memory utilization:

  • Heap—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—Percentage of buffer space being used by the FPC processor for buffering internal messages.

Exhaust A temperature

Temperature of the air flowing past Exhaust A.

Exhaust B temperature

Temperature of the air flowing past Exhaust B.

Total DDR DRAM

Amount of double data rate dynamic random access memory (DDR DRAM) available to the FEB CPU.

Total RLDRAM

Amount of reduced latency dynamic random access memory (RLDRAM) available to the FEB CPU.

Start time (Detail output only)

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

Uptime (Detail output only)

How long the Routing Engine has been connected to the FEB, and therefore, how long the Flexible PIC Concentrator (PIC) has been up and running.
