Monitor the HCM Status

To monitor the HCM status:

1. Check HCM LEDs
2. Check HCM Environmental Status
3. Check the Companion Routing Engine Status

Check HCM LEDs

Purpose

To monitor the HCM status by checking the HCM LEDs on the component faceplate.

Action

To check the HCM LEDs, look at the component faceplate at the bottom left front of the M10i router chassis (see Table 1).

Two LEDs indicate HCM status—a green PWR LED and a blue MSTR LED. describes the LED states.

Check HCM Environmental Status

Purpose

To isolate problems in the HCM by checking the environmental status.

Action

To check the HCM environmental status, use the following command:

Sample Output

HCM 0 status:
			 State 												Online Master
			 FPGA Revision 								27
		 HCM 1 status:
			State 												Present Standby
			FPGA Revision 									27

Meaning

The command output shows that the HCM status, including slot number, operating state, and field programmable gate array (FPGA) revision.

To display the environmental status of a particular HCM, use the following command:

Check the Companion Routing Engine Status

Purpose

The HCM in the slot labeled HCM0 is paired with the Routing Engine in the slot labeled RE0. Likewise, the HCM in the slot labeled HCM1 is paired with the Routing Engine in the slot labeled RE1. By default, the HCM in the slot labeled HCM0 is the master.

When HCM mastership changes because of failure, Routing Engine mastership changes as well.

Action

To check Routing Engine status, use the following command:

Sample Output

Routing Engine status:
  Slot 1:
	  Current state                  Backup
	  Election priority              Backup (default)
	  Temperature                35 degrees C / 95 degrees F

	  Uptime                      30 days, 12 hours, 41 minutes, 15 seconds

Meaning

The command output displays the operating state of both Routing Engines installed in the router chassis, including slot number, current state, and default election priority—master or backup. The command output also displays the Routing Engine temperature, amount of memory, and the percentage of memory and CPU utilization. The command output displays the Routing Engine model number, serial number ID, start time, and total operating time.

Look at the Routing Engine LEDs by using the show chassis routing-engine command or by looking at the component faceplate at the front of the router. The Routing Engine has four LEDs that tell operating status: a green LED labeled HDD, a blue LED labeled MASTER, a red LED labeled FAIL, and a green LED labeled ONLINE. Table 2 describes the Routing Engine LED states.
