Asimple way to think of dual-port sub codes is as the decimal equivalent of 7030 + n (expressed in hexadecimal), where n is the card instance number. For example, for the device file x25_1p2, the sub in hexadecimal would be

		7030 + 1 = 7031
		which, when converted to decimal gives you 28721.
		Some sample calculations of the sub code for dual-port
		cards are provided in the table below.
NOTE		When specifying the name of device files in systems
		with dual-port cards, you must use the form
		x25_npx
		where n represents the card number (0 to 15, and the
		first card must be zero), the letter p is a place holder
		(for port), and x represents the interface (port) number
		(1 or 2).
Table 7-6	Dual-port Subnet Interface Codes
		Interface	Calculation	Sub code
			(hexadecimal)	(decimal)
	x25_0p1, x25_0p2		7030 + 0 = 7030	28720
	x25_1p1, x25_1p2		7030 + 1 = 7031	28721
	x25_2p1, x25_2p2		7030 + 2 = 7032	28725
	x25_5p1, x25_5p2		7030 + 5 = 7035	28725
	pri	Specifies the logging priority level. Collects messages
		from the level equal to or less than the value given by
		pri. Values 1 to 6 are allowed for X.25 level 3, 1 to 4 for
		level 2, and 1 to 5 for IP over X.25.
