   atm Kernel Subsystem
       This section lists and describes attributes for the base ATM (atm) kernel subsystem.

	      The  percentage of each ATM driver's total interface bandwidth that is available to constant bit rate (CBR) circuits in the backward
	      or incoming direction. Use the atmconfig command to set this limit on a per-driver basis.

	      Default value: 10 (percent)

	      Minimum value: 0

	      Maximum value: 100

	      The level of verbosity for messages displayed by the ATM Connection Management Module (CMM). If the value is  greater  than  -1,	it
	      overrides the value of the global_msg_level attribute.  Subsystem Message Level Values lists the attribute values and their meaning.

	      Default value: -1 (use global_msg_level value)

	      Minimum value: -1

	      Maximum value: 2

	      Default value: 10 (percent)

	      Minimum value: 0

	      Maximum value: 100

	      Minimum value: 0

	      Maximum value: 3000

	      The percentage of each ATM driver's total interface bandwidth that is available to constant bit rate (CBR) circuits in the  backward

       subsystem.

	      Minimum value: 2

	      Maximum value: 100

	      The level of verbosity for messages displayed by the UNI3X subsystem. If the value is greater than -1, it overrides the value of the
	      global_msg_level attribute. Subsystem Message Level Values lists the attribute values and their meaning.

	      Default value: -1 (use global_msg_level value)

   Subsystem Message Level Values
       This section lists the valid values for setting the message level for the atm, atmilmi3x, atmip, atmuni, lane, and uni3x kernel subsystems.
       Normal  message	level.	Displays subsystem initialization messages, important state changes, and significant error conditions. This is the
       default level for the global_msg_level configuration attribute.	Informational level. In addition to information displayed at the  previous
       level,  displays  messages for normal virtual circuit (VC) release events, transient errors, and signaling and ILMI state changes.  Verbose
       level. In addition to information displayed at the previous level, displays detailed information on connection failures, state changes, and
       unexpected events that is needed for diagnosing ATM problems.
