Configuration Table |
![]() |
This table contains all LAN Emulation Servers this agent manages. The LES is one of
the components in the Emulated LAN which implements the control coordination function. It
is the address resolution server for a given ELAN. The LES provides a facility for
registering and resolving MAC addresses and/or route descriptors to ATM addresses. There
can be multiple LES per ELAN but a LES can serve only one ELAN. Each entry in this table represents a LES. The parameters in each entry apply to one emulated LAN served by one LES. Objects lesLanType and lesMaxFrameSize are also required besides lesRowStatus during row creation. |
lesConfIndex | A value which uniquely
identifies a conceptual row in the lesConfTable. If the conceptual row identified by this value of lesConfIndex is recreated following an agent restart, the same value of lesConfIndex must be used to identify the recreated row. |
lesAtmAddrSpec | An ATM address specified by the network or
local management that, with the ATM address mask, determines a portion of the ATM address
that the LES on the designated ATM interface will use to derive the actual ATM address
from the network or ILMI. The derived ATM address is specified in the object
lesAtmAddrActual, which is used to receive ATM ARP requests. REFERENCE: |
lesAtmAddrMask | The ATM address mask associated with the
object lesAtmAddrSpec. The value of the mask is an ATM address with the don't care portion
set to zero and the valid ATM address portion set to one. REFERENCE: |
lesAtmAddrActual | The resultant ATM address in use by the
LES. This object is a product of the specified ATM address, mask and interaction with the
network. This object is created by the agent. REFERENCE: |
lesElanName | The name of the Emulated LAN this LES is
providing service for. This object may be used to identify the ELAN the LES is in. REFERENCE: |
lesLanType | The type of the ATM Emulated LAN this LES
is providing service to. REFERENCE: |
lesLastChange | The value of sysUpTime when this LES has entered the state indicated by the object lesOperStatus. |
lesMaxFrameSize | The maximum AAL-5 SDU size of a data frame
that the LE service can guarantee not to drop because it is too large. REFERENCE: |
lesControlTimeOut | Time out period used for timing out most
request/response control frame interactions. This is the time a Client has to issue a join
request to a LES after a control direct VCC is established with a LES. REFERENCE: |
lesOperStatus | The operational state of this LES entry. When in 'up' state the LES will respond to LEC requests. Any other state the LES is not available for service and may release all the existing VCCs and refuse service to all clients. |
lesAdminStatus | The desired state of the designated LES as prescribed by the operator. The actions of the agent will, if at all possible, eventually result in the desired state being reflected in the lesOperStatus. |
lesRowStatus | This object is used to create or delete
entries in the elanConfTable. REFERENCE: |
BUS Table |
![]() |
This table contains the BUSs paired with the LESs found in the lesConfTable. The BUS (Broadcast and Unknown Server) handles data sent by a LE client to the broadcast MAC address, all multicast traffic, and initial unicast frames which are sent by a LAN Emulation Client before the data direct target ATM address has been resolved. |
lesBusConfIndex | A value which uniquely
identifies a BUS ATM address. If the BUS ATM address identified by this value of lesBusConfIndex is recreated following an agent restart, the same value of lesBusConfIndex must be used to identify the recreated BUS ATM address. |
lesBusAddress | The ATM address of the BUS. This BUS is
associated with LES specified by the lesConfIndex. A BUS may have several ATM addresses,
this object provides the ATM address the LES returns in response to the LE-ARP request by
the LEC. REFERENCE: |
LE ARP MAC Address Table |
![]() |
This table provides access to an ATM LAN Emulation Server's MAC-to-ATM ARP table. It
contains entries for unicast addressed, the broadcast address. When the entry is for broadcast MAC address the corresponding ATM address is of a BUS. When the entry is for unicast MAC address the corresponding ATM address represents a LEC. |
lesLeArpMacAddr | The MAC address for which this table entry
provides a translation. Since ATM LAN Emulation uses an LE ARP protocol to locate the
Broadcast and Unknown Server, the value of this object could be the broadcast MAC address. MAC addresses should be unique within any given ATM Emulated LAN. However, there's no requirement that they be unique across disjoint emulated LANs. |
lesLeArpLecId | The LE Client Identifier (LECID) of this
entry. Each LE Client requires a LECID assigned by the LE Server during the Join phase. If this entry is for a BUS then this object value will be zero. |
lesLeArpAtmAddr | The ATM address of the Broadcast & Unknown Server or LAN Emulation Client whose MAC address is stored in 'lesLeArpMacAddr'. This volume may be registered by a LAN Emulation Client or specified by network management. |
lesLeArpEntryType | This object is used to indicate how this
LE-ARP entry was created. The possible values for this object are: viaRegister(1), - agent staticVolatile(2), - network manager staticNonVolatile(3) - network manager This object is filled in by agent or network manager depending on the type. REFERENCE: |
lesLeArpRowStatus | This object is used to create or delete
entries in the elanConfTable. REFERENCE |
LE ARP Route Descriptor Table |
![]() |
This table provides access to an ATM LAN Emulation Server's RouteDescriptor-to-ATM ARP
cache. The entries in this table are set-up by the agent or network manager
depending on the entry type. The Route Descriptors are presented as Segment Id (ring number) and Bridge number. |
lesLeArpRdSegId | The LAN ID (ring number) portion of the IEEE 802.5 route descriptor associated with this LES. |
lesLeArpRdBridgeNum | The Bridge Number portion of the IEEE 802.5 route descriptor associated with this LES. |
lesLeArpRdLecId | The LE Client Identifier (LECID) of this entry. Each LE Client requires a LECID assigned by the LE Server during the Join phase. |
lesLeArpRdAtmAddr | The ATM address associated with the Route Descriptor. |
lesLeArpRdEntryType | This object is used to indicate how this
LE-ARP entry was learned:
This object is filled in by agent or network manager depending on the type. |
lesLeArpRdRowStatus | This object is used to create or delete
entries in the elanConfTable. REFERENCE: |
LEC Table |
![]() |
This table contains all LAN Emulation clients serviced by LESs specified in the lesConfTable. This table can be used to retrieve the topology of an ELAN, in particular, the LES to LECs mapping information. An entry in this table is filled in by the agent when a LEC registers successfully with the LES. Objects lesLecCtlDirectVpi and lesLecCtlDirectVci can be modified by the network manager after creation if PVC is used. |
lesLecIndex | An arbitrary integer which uniquely identifies a LEC in this table. |
lesLecAtmAddr | The ATM address of the LANE
client. This is the primary ATM address of the LEC used in joining phase. REFERENCE: |
lesLecProxy | Whether this client is acting
as a proxy. Proxy clients are allowed to represent unregistered MAC addresses,
and receive copies of LE_ARP_REQUEST packets for such addresses. REFERENCE: |
lesLecId | The LE Client Identifier (LECID) of this entry. Each LE Client requires a LECID assigned by the LE Server during the Join phase. The LECID is placed in control requests by the LE Client and MAY be used for echo suppression on multicast data frames sent by that LE Client. |
lesLecAtmIfIndex | The ifIndex of ATM port where this LEC entry has established the control direct VCC to the LES. The value of this object maps to an existing ifIndex value in the ifTable of MIB-II. When an internal connection is used, this object is set to zero. |
lesLecCtlDirectVpi | The VPI of the bi-directional control direct connection between the LEC and LES. |
lesLecCtlDirectVci | The VCI of the bi-directional control direct connection between the LEC and LES. |
lesLecLastChange | The value of sysUpTime of this entry when the LEC enters the state indicated by the object lesLecState. |
lesLecState | This object is used to indicate the status this LEC entry is in from the LES's perspective. The state of this object is updated by the agent as it discovers various phases of this LEC. |
lesLecRowStatus | This object provides a way for the network
manager to selectively remove a LE Client from the designated LES. Or in a system where
PVCs are used, this table is used to configure Control Direct VCCs between LES and LEC. REFERENCE: |

lesStatLeArpFwd | The number of LE_ARP_REQUESTs that the LES
forwarded onto the clients (either via the control distribute or individually over each
control direct) rather than answering directly. This may be due to implementation decision (forward all requests) or because the resolution to the request did not reside in the LES's LE ARP cache. |

lesErrLogIndex | An arbitrary integer which uniquely identifies an error log entry. The first entry after reset or clearing the error log is an assigned value (2^32-1). Succeeding entries are assigned with descending values consecutively. Entries after 1 are discarded. The enabling/disabling of the error log capability is done in the lesErrCtlTable. |
lesErrLogAtmAddr | The ATM address of the requester which sends the JOIN or REGISTER request and causes the error to occur. The corresponding error code is specified in the object lesErrLogErrCode. |
lesErrLogErrCode | The Error code which indicates the cause of the error triggered by the JOIN or REGISTER request sent by the requester indicated by the value of the object lesErrLogAtmAddr. |
