HP ArubaOS-CX: power-consumption starting with version FL.10.13.xxxx - permanent power changes logged

[TerraTalpi]

Hello dear team,

the ArubaOS-CX switches in Version FL.10.13.xxxx introduce a new sub-command show environment power-consumption with the following example output:

Power Consumption Averaging Period : 600 seconds

                                    Instantaneous     Average
Name Description                        Power (W)   Power (W)
---------------------------------------------------------------
1    6300M 24SFP+ 4SFP56 Swch               52.00       51.73

The parameter power-consumption was not available in the previous Long Support Release (LSR) Version FL.10.10.xxxx. The Power(W) values always change and produce a new change in odixized every time scanned. I guess this should be easily fixable by doing something like the fix for the fan speed in the current version, see commit ed094ff2e93d1ab4627d0cb183d4bd9273745a42 and/or pull-request #2865. I will try to implement this change and create a pull-request if possible.

@alextremblay has checked my pull request and informed me, that there is still a change produced with my currently submitted regex, since the number of digits could change. Therefore, I will test the regex again against this example output with a stack consisting of three switches, each with a different power consumption:

show environment power-consumption

Power Consumption Averaging Period : 600 seconds

                                    Instantaneous     Average
Name Description                        Power (W)   Power (W)
---------------------------------------------------------------
1    6300M 24SFP+ 4SFP56 Swch               52.00       51.73
2    6300M 48G 4SFP56 Swch                 156.00      155.94
3    6300M 48G 4SFP56 Swch                1156.00     1155.94

Please note that this is not an actual command output, but created by me, since I lack a switch (stack) that consumes more than 1000 Watts.

I have now further investigated this issue and checked the AOS-CX 10.13 Command-Line Interface Guide documentation about that command in the newest version FL.10.13.xxxx for various switch series. CLI Guides link:

• 6000 and 6100 switch series
• 6300 and 6400 switch series
• 832x switch series
• 8360 switch series
• 8400 switch series
• 10000 switch series

The output differs depending on the following factors:

• Switch Model
• VSF stack or standalone
• chassis switch with linecards

The different outputs may be the ones I posted previously for a VSF or standalone switch, but also the following (copied copied from the AOS-CX 10.13 Command-Line Interface Guides of multiple switch types):

Please note, that I had to manually insert the spaces again, since they could not be copied out of the PDF.

I will create Regex expressions for the above outputs and add them to the pull request.
