ATM Forum LANE Configuration MIB

This is the MIB module for managing ATM Emulated LANs as well as LAN Emulation Configuration Server (LECS). It provides mechanism for constructing and destroying ELANs, for distributing members of an ELAN and for figuring out the topology of an ELAN. It also provides management information for LECS.

elanConfNextId The next available ELAN index provided by the agent. The value of this object can be used as the index to the elanConfTable during creation.

 

ELAN Configuration Table 

up_arrow138b.gif (883 bytes)
This table contains all Emulated LANs (ELANs) this agent manages. An ELAN is defined by the ELAN name, a set of TLVs, and other parameters. After an ELAN is created, members of the ELAN such as the LAN Emulation Server (LES) or Client (LEC) can be added to this ELAN entry in their respective tables. There are four members to an ELAN and they are LECS, LES, BUS (Broadcast and Unknown Server ) and LEC. The support of LECS is optional. The addition and deletion of LECS is done in the elanLecsConfGroup defined in this MIB. The addition and deletion of the LEC are done in the LEC Assignment tables defined in this ELAN Configuration group. The addition and deletion of the LES are also defined in this group. The addition and deletion of the BUS are done in the LES MIB due to the fact that LEC learns the BUS address only from the LES it corresponds to.

Field Descriptions

elanConfIndex A value which uniquely identifies a conceptual row in the elanConfTable.

If the conceptual row identified by this value of elanConfIndex is recreated following an agent restart, the same value of elanConfIndex must be used to identify the recreated row.

elanConfName The name of this Emulated LAN entry. When this object length is zero then the ELAN name is not specified. The clients assigned to this ELAN will also have a zero length string as the ELAN name.

The value of this object is used in the LE CONFIGURE response by the LECS if supported.

Note that ELAN name may be used as cross reference to the LES MIB and BUS MIB though not required. Multiple ELANs with no ELAN name specified will cause conflicts in reference to LES and BUS MIBs.

REFERENCE:
LAN Emulation Over ATM Specification - version 1.0. C5.

elanConfTlvIndex The value of this object identifies one or more rows in the lecsTlvTable which applies to this ELAN. This object is set to zero if 1) LECS is not supported. or 2) there is no TLV associated with this entry.
elanConfLanType The LAN type of this ELAN entry.

REFERENCE:
LAN Emulation Over ATM Specification - version 1.0. S2.

elanConfMaxFrameSize The maximum data frame size of this ELAN entry. The maximum AAL-5 SDU size of a data frame that this ELAN can support. The value of this object is returned to the LEC in the LE CONFIGURE response.

REFERENCE:
LAN Emulation Over ATM Specification - version 1.0. S3.

elanConfRowStatus This object is used to create or delete entries in the elanConfTable.

REFERENCE:
RFC 1443, [10] Textual Conventions for version 2 of the Simple Network Management Protocol (SNMPv2).

 

ELAN LES  Table

up_arrow138b.gif (883 bytes)
This table contains all LESs for each ELAN specified in the elanConfTable. Each ELAN can have more than one LES providing LAN Emulation services. Each LES can service only one ELAN. The table is indexed by the elanConfIndex which points to the ELAN this LES is providing service to, and elanLesIndex which uniquely identifies a LES. This table is used for configuration of an ELAN only, that is, creating a LES in this table does not instantiate a LES in the network. It is done in the LES MIB.

Field Descriptions

elanLesIndex An arbitrary number which uniquely identifies the LES this entry pertains to.
elanLesAtmAddress The ATM address of the LES entry. If LECS is supported, the value of this object is the LES ATM address LECS returns to the LEC in the CONFIGURE response. If LECS is not supported, the value of this object pertains to the LES ATM address network manager provides to the LEC.
elanLesRowStatus This object is used to create or delete entries in the elanLesfTable.

REFERENCE:
RFC 1443, [10] Textual Conventions for version 2 of the Simple Network Management Protocol (SNMPv2).

 

ELAN Policy Table

up_arrow138b.gif (883 bytes)
This table contains all policies this agent supports for assigning a LEC to an ELAN. A set of policies with the same or different priorities can be selected by the entity which provides ELAN configuration service such as the LECS. The policy with the highest priority or with the smallest elanPolicyPriority , is evaluated first. The policies with the same elanPolicyPriority are evaluated at the same time with the AND operation. When LECS receives a configure request, it checks it's policies selected from this table to determine which ELAN and LES the LEC will join. This table is indexed by a selector index and a policy index. The policy index uniquely identifies a policy and the selector index allows multiple policies be selected by one LECS or an entity that is providing ELAN configuration service.

Field Descriptions

elanPolicySelectorIndex The value of this object indicates a group of policies that can be selected by the ELAN configuration service provider such as the LECS.
elanPolicyIndex The value of this object uniquely identifies a single policy entry in this table.
elanPolicyPriority The priority of this policy entry. Policies are evaluated by the entity which provides ELAN configuration service (LECS) by their priorities. Policies with the same priority values should be evaluated at the same time with an AND operation. That is, if one of the policy with the same priority is not met, the evaluation should fail. The value 1 has the highest priority.
elanPolicyType The value of this object must reference a definition of a type of policy. Some of such definition exist within the elanAdminPolicyVal subtree. Others may be defined within enterprise specific subtrees. The agent is not required to support every types defined within the elanAdminPolicyVal subtree.
elanPolicyRowStatus This object is used to create or delete entries in the elanPolicyTable.

This table is indexed by the elanConfIndex which points to the ELAN this LEC belongs, the elanLesIndex which points to the LES this LEC should join, the LEC's ATM address and an ATM address mask. Portions of ATM address can be used in determining ELAN membership by using both the ATM address and the mask.

Field Descriptions

elanLecAtmAddress The value of this object is the ATM address of a LAN Emulation client. This object and the object elanLecAtmMask are used to form an ATM address or portion of an ATM address to be used by the LECS in determining the ELAN membership when the policy of this LECS is by ATM address.
