Determining the type of device

Sometimes it is useful to find out what kind of device the script is running on, so that it can be deployed on multiple types of PremierWave devices without modifying.

The code below creates the pwDevice class. When an instance of this class is created, it will first find out what the MAC address of the device is. This can be useful to use as a unique identifier. It will then determine which type of device it is. As an example, it also creates a property called import_file which is a string with the path of the file used for importing configuration. This will become useful if a program needs to change configuration of the device.

class pwDevice:
	def __init__(self):
		mac = commands.getoutput("ifconfig eth0| grep HWaddr | awk '{ print $5 }'").strip()			
		self.mac = mac.translate(None,':')
		if os.path.exists('/ltrx_user/pwxcr/pwxc_hspa_import.xcr'):
			self.type = "PremierWave XC HSPA+"
			self.import_file = '/ltrx_user/pwxcr/pwxc_hspa_import.xcr'
		elif os.path.exists('/ltrx_user/pwxcr/pwxn_import.xcr'):
			self.type = "PremierWave XN"
			self.import_file = '/ltrx_user/pwxcr/pwxn_import.xcr'
		elif os.path.exists('/ltrx_user/pwxcr/pwen_import.xcr'):
			self.type = "PremierWave EN"
			self.import_file = '/ltrx_user/pwxcr/pwen_import.xcr'
		elif os.path.exists('/ltrx_user/pwxcr/pwse1000_import.xcr'):
			self.type = "PremierWave SE1000"
			self.import_file = '/ltrx_user/pwxcr/pwse1000_import.xcr'
		else:
			self.type = "Unknown"
