sical IP services (atmip) ATM Forum signaling and Integrated Layer Man‐

atm Kernel Subsystem
This section lists and describes attributes for the base ATM (atm) ker‐
nel 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 Connec‐
tion Management Module (CMM). If the value is greater than -1,
it overrides the value of the global_msg_level attribute. Sub‐
system 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 Hewlett-Packard 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 Inte‐
grated 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 ser‐
vices (atmip) kernel subsystem.
The level of verbosity for messages displayed by the ATMIP sub‐
system. If the value is greater than -1, it overrides the value
of the global_msg_level attribute. Subsystem Message Level Val‐
ues 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 sub‐
system.
The level of verbosity for messages displayed by the ATMUNI sub‐
system. If the value is greater than -1, it overrides the value
of the global_msg_level attribute. Subsystem Message Level Val‐
ues 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 Emu‐
lation (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 sub‐
system. If the value is greater than -1, it overrides the value
of the global_msg_level attribute. Subsystem Message Level Val‐
ues 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 ker‐
nel 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 sys‐
tem. 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
Maximum value: 262144
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 resolu‐
tion
Minimum value: 2
Maximum value: 100
The level of verbosity for messages displayed by the UNI3X sub‐
system. If the value is greater than -1, it overrides the value
of the global_msg_level attribute. Subsystem Message Level Val‐
ues 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. Infor‐
mational 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. Ver‐
bose 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.
