Configuration Table |
![]() |
A table describing all the LES components which this managed device supports. |
decLesIndex | A unique number greater than zero which identifies this table row. |
decLesRowStatus | This object is used to create and delete
LAN Emulation Server components. If this object is writable, it will accept the values:
under suitable conditions. Use decLesAdminStatus to enable and disable service. |
decLesAdminStatus | The desired state of this LES component. When a LES is distributed, this object controls the 'local' server component, as opposed to the overall state of the LES. If a BUS is connected to the LES, enabling/disabling either server may affect both of them. Otherwise it is up to the network manager to coordinate the state of the servers. |
decLesOperStatus | The operational state of this LES
component. A LES component may not become operational until it has been configured with values for:
When a LES is in the 'disabling' or 'deleting' state, attempts to set decLesAdminStatus to 'up' will fail. |
decLesLastChange | The value of sysUpTime at the time that this server last entered its current operational state. If the current state was entered prior to the last re-initialization of the local network management subsystem, then this object contains a zero value. |
decLesAtmAddress | The ATM address of this LAN Emulation
Server, or LAN Emulation Server component. Clients establish Control Direct VCCs to this address to initiate the process of Joining the emulated LAN. |
decLesDescription | A human-readable string which can contain anything the network manager wants. |
decLesLanName | The name of this emulated LAN. This can be
any string that the network manager would like this LES component to pass out to new
clients. This string is not guaranteed to uniquely identify the emulated LAN. REFERENCE: |
decLesLanType | The data frame format for this emulated
LAN. In an active emulated LAN, this parameter MUST have a consistent value in all of the LES and BUS components serving the emulated LAN. Otherwise various problems may result. The value of this columnar object may only be changed when this LAN Emulation Server has no active clients, and 'decLes[Admin,Oper]Status' are 'down'. REFERENCE: |
decLesMaxDataFrameSize | The maximum AAL-5 SDU size for data frames
sent over this emulated LAN. This must be one of the standard sizes defined in the LAN
Emulation specification. In an active emulated LAN, this parameter MUST have a consistent value in all of the LES and BUS components serving the emulated LAN. Otherwise various problems may result. The value of this columnar object may only be changed when this LAN Emulation Server has no active clients, and 'decLes[Admin,Oper]Status' are 'down'. REFERENCE: |
decLesAtmAddressOfBUS | The ATM address of the Broadcast and
Unknown Server component associated with this LES component. Unless otherwise stated in product documentation, the value of this columnar object may only be changed when this LAN Emulation Server has no active clients, and'decLes[Admin,Oper]Status' are 'down'. |
decLesControlTimeout | S4 Control Time-out. Time out period used
for timing out most request/response control frame interactions, as specified elsewhere.
Once a LE Client establishes a Control Direct VCC to the LE Server, the Join phase must
complete within the Join Time-out time. If not, the LE Service SHOULD release any Control
VCCs to that LE Client, terminating the Join phase. If a LES is distributed, each of its servers should have the same value for this parameter. REFERENCE: |
decLesArpResponsePolicy | Lets you fine-tune the performance of an
emulated LAN by controlling the distribution of LE_ARP_RESPONSEs. You can choose from one of three policies:
|
decLesNarpRequestPolicy | Controls whether this LES forwards LE_NARP_REQUESTs. |
decLesTopologyChangeMode | The Topology Change mode which this LE
Server believes the emulated LAN is in, based upon the Topology Change requests it has
seen and/or generated. The value 'true' indicates accelerated aging mode - as opposed to normal aging mode. |
decLesLastTcModeChange | The value of sysUpTime at the time that the object 'decLesTopologyChangeMode' last acquired its current value. If the current value was acquired prior to the last re-initialization of the local network management subsystem, then this object contains a zero value. |
decLesTopologyChangeTimeout | Provides a guard against an emulated LAN
remaining in accelerated aging mode forever. If an emulated LAN remains in the accelerated aging state for more than 'decLesTopologyChangeTimeout' seconds following the last Topology Request, the LE Server will automatically issue a Topology Request frame to reset all the clients to normal aging mode. This value is measured in seconds, and should be set higher than the normal time between bridge BPDUs. |
