NAME

sys_attrs_atm, sys_attrs_atmilmi3x, sys_attrs_atmip, sys_attrs_atmuni, sys_attrs_lane, sys_attrs_uni3x - Asynchronous Transfer Mode (ATM) subsystem attributes  

DESCRIPTION

This reference page lists and describes attributes for the following Asynchronous Transfer Mode (ATM) kernel subsystems: 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 (lane) ATM Forum signaling (uni3x) Refer to the sys_attrs(5) reference page for an introduction to the 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: 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
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: 0
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 Compaq Computer Corporation support personnel or by patch kit documentation.
Default value: 30 (seconds)
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 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: 64 (buckets)
Minimum value: 16
Maximum value: 512
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
 

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
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
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

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.
