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

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

Default value: -1 (use
global_msg_level
value)

to set this limit on a per-driver basis.
-
Default value: 0 (percent)
-
Minimum value: 0
-
Maximum value: 100
atmilmi3x Kernel Subsystem
This section lists and describes attributes for the ATM Forum Integrated
Layer Management Interface (atmilmi3x) kernel subsystem.

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)
-
Minimum value: -1
-
Maximum value: 2
atmip Kernel Subsystem
This section lists and describes attributes for the Classical IP services
(atmip) kernel subsystem.
-
The level of verbosity for messages displayed by the ATMIP
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)
-
Minimum value: -1
-
Maximum value: 2
atmuni Kernel Subsystem
This section lists and describes attributes for the ATM Forum signaling
and Integrated Layer Management Interface support (atmuni)
kernel subsystem.
-
The level of verbosity for messages displayed by the ATMUNI
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)
-
Minimum value: -1
-
Maximum value: 2
lane Kernel Subsystem
This section lists and describes attributes for the ATM Forum LAN Emulation
(lane) kernel subsystem.
-
The number of LE_ARP hash table buckets. The LE_ARP table
is used in resolving Ethernet MAC addresses into ATM addresses.
-
Default value: 64 (buckets)
-
Minimum value: 16
-
Maximum value: 512

global_msg_level
value)
-
Minimum value: -1
-
Maximum value: 2
-
The maximum number of emulated LANs that you can configure
on a system. The maximum number is determined by the number of End System
Identifiers (ESIs) available on the system.

Default value: 4 (ELANs)
-
Minimum value: 0
-
Maximum value: 64
uni3x Kernel Subsystem
This section lists and describes attributes for the ATM Forum signaling
(uni3x) kernel subsystem.
-
The maximum number of ATM adapters that can use ATM signaling.
If you increase the default value, you increase the amount kernel memory required
by the ATM subsystem.
-
Default value: 16 (adapters)
-
Minimum value: 1
-
Maximum value: 64
-
The maximum number of ATM connections (SVCs) allowed by the
system. If you increase the default value, you increase the amount kernel
memory required by the ATM subsystem.
-
Default value: 4096 (connections)
-
Minimum value: 16
-
Maximum value: 262144

amount kernel memory required by the ATM subsystem.
-
Default value: 1024 (connections)
-
Minimum value: 16
-
Maximum value: 262144
-
The maxiumum number of parties (endpoints) allowed on a point-to-multipoint
virtual circuit (VC).
-
Default value: 32768 (endpoints)
-
Minimum value: 1
-
Maximum value: 32768

-
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)
-
Minimum value: -1
-
Maximum value: 2
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.
