Base ATM support (atm) ATM Forum Integrated Layer
Management Interface (atmilmi3x) Classical IP services
(atmip) ATM Forum signaling and Integrated Layer Management
Interface support (atmuni) ATM Forum LAN Emulation

topic of kernel subsystem attributes.
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: 1
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
The percentage of each ATM driver's total interface
bandwidth that is available to constant bit rate
(CBR) circuits in the forward or outgoing direction.
Use the atmconfig command to set this limit
on a per-driver basis.
Default value: 10 (percent)
Minimum value: 1
Maximum value: 100
The level of verbosity for messages displayed by
all components in the ATM subsystem. Subsystem
Message Level Values lists the attribute values and
their meaning.
Default value: 0 (normal message level)
Minimum value: 0
Maximum value: 2
The number of seconds after which unused reserved
resources are revoked via an ATM_CME_RESV_EXPIRE
exception notification.
Do not modify the default setting for this
attribute unless instructed to do so by HewlettPackard
Company support personnel or by patch kit
documentation.
Default value: 30 (seconds)
Minimum value: 1
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 or incoming and forward
or outgoing direction. Use the atmconfig command
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.
The level of verbosity for messages displayed by
the ATMILMI3X 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: 128 (buckets)
Minimum value: 32
Maximum value: 1024
The level of verbosity for messages displayed by
the LANE 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
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
The maximum number of mbufs enqueued on a virtual
circuit's (VC's) output queue before packets are
dropped.
Default value: 512 (bytes)
Minimum value: 0
Maximum value: 65535
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
The maximum number of point-to-multipoint ATM connections
allowed by the system. If you increase the
default value, you increase the amount kernel memory
required by the ATM subsystem.
Default value: 1024 (connections)
Minimum value: 16

The maxiumum number of parties (endpoints) allowed
on a point-to-multipoint virtual circuit (VC).
Default value: 32767 (endpoints)
Minimum value: 1
Maximum value: 32768
The number of ticks per second of the signaling
module timers. If you increase this value, you
achieve better precision, but with greater processor
overhead.
Default value: 10 (ticks per second), or 100-millisecond
resolution
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 [Toc] [Back]
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.
