get_facts doesn't work on stacked switches

[rgilijamse]

Parsing breaks when multiple results are returned from show commands due to the switches being stacked.

Error:

  File "<PATH>/napalm_procurve/procurve.py", line 254, in get_facts
    serial_number = line.split(" : ")[2].strip()
IndexError: list index out of range

Sample output:

SWITCH# show system

Cool. Thanks for the report. I've never used stacked ProCurve switches so far.

Is there a clear indicator that a switch is stacked? And how do other show xxx commands behave? Do they also merge output from the stack members by prefixing it with "Member :x"?

show interfaces brief seems to work the same, just different port names (1/1, 1/2, etc.)
if you have a quick way to test show_model, let me know.

Edit:
no indicator that it's stacked, but an easy way to check is show stacking. For non-stacked switches output is simple:

SWITCH-2# show stack
Stacking is disabled.

Thank you. What does show stack show on your device?

I still have some 2650s lying around somewhere in a datacenter, I gotta pick them up and test them out to see how the stacking behaves and use it as a test...
