Viewing Switch Temperature

Cisco DCNM includes the module temperature sensor monitoring feature, using which you can view the sensor temperature of a switch. You can choose an interval by which to filter the sensor list. The default interval is Last Day. Only sensors that have historical temperature data is shown in the list. You can choose between Last ten Minutes, Last Hour, Last Day, Last Week, and Last Month.

Note

It is not necessary to configure the LAN credentials under the Configure > Credentials Management > LAN Credentials screen to fetch the temperature monitoring data from the switches.


To view the switch temperature information from the Cisco DCNM Web UI, perform the following steps:

Procedure


Step 1

Choose Monitor > Switch > Temperature.

The Switch Temperature window is displayed with the following columns.

  • Scope: The sensor belongs to a switch, which is part of a fabric. The fabric that it belongs to is shown as its scope. When the scope selector at the top of Cisco DCNM is used, the sensor list is filtered by that scope.
  • Switch: Name of the switch the sensor belongs to.
  • IP Address: IP Address of the switch.
  • Temperature Module: The name of the sensor module.
  • Avg/Range: The first number is the average temperature over the interval that is specified at the top of the table. The second set of numbers is the range of the temperature over that interval.
  • Peak: The maximum temperature over the interval
Step 2

From this list, each row has a chart icon, which you can click.

A chart is displayed, which shows historical data for the sensor. The interval for this chart can be changed as well, between 24 hours, 1 week, and 1 month.

    • Peak Rx/Tx % = Peak Rx/Tx divided by Speed * 100
Note 
If the performance tables do not contain any data, see the Performance Setup Thresholds section to turn on performance.

Monitoring a vPC

The virtual port channel (vPC) feature enables you to view the links that are physically connected to different devices as a single port channel. A vPC is an extended form of a port channel which allows you to create redundancy and increase bisectional bandwidth by enabling multiple parallel paths between nodes and allowing load balancing traffic. Traffic is distributed among two single device vPC endpoints. If there is an inconsistency in the vPC configurations, the vPC does not function correctly.


Note

To view the vPC in vPC Performance, both primary and secondary device should be designated to the user. If either one kind of switch is not designated, vPC information is isplayed.


Cisco DCNM Web Client > Monitor> vPC displays only consistent vPCs displays both the consistent and inconsistent vPCs.

You can identify the inconsistent vPCs and resolve the inconsistencies in each vPC by using the Cisco DCNM Web UI > Configure > Deploy > vPC Peer and Web Client > Configure > Deploy > vPC.

Table 1 displays the following vPC configuration details in the data grid view.
