A LEC provides the intermediate layer between the connectionless application-to-MAC layer and the connection-oriented layer of ATM. A LEC is identified by a combination of ATM address and MAC address. A LEC resolves LAN addresses to ATM addresses and filters incoming unicast and multicast traffic to ensure that it is destined for the end system represented by the LEC.
LECs may be members of one or more ELANs. Membership in an ELAN does not depend on physical location, and an end user may belong to more than one emulated LAN, but clients cannot communicate across LAN boundaries.
If you do not use the adapter address as the LE client's ESI address, enter the locally administered ESI for the LE client ESI address. If you do not select the adapter address, then only those locally administered ESI addresses that have been configured and enabled for this ATM interface are valid.
Valid Values: any valid MAC address.
This address must be unique across all LECs on the ELAN.
Note. Only one LEC on a given ELAN can use the burned-in MAC address.
Default Value: none
Valid Values: a single octet value that is unique for this LEC and within the range of reserved selector values for the ESI you selected.
If you indicate 'Yes', you can enter the ATM address of the LE Configuration Server, and you do not have to configure the ATM address of the LE Server.
Valid Values: any ATM address
Default Value: none
Otherwise, you enter the ATM address of the LE Server this client will use.
Valid Values: any ATM address
Default Value: none
The value specified for frame-size must be equal to or less than the value specified for ATM max-frame using the Adapter Interface Set option. Select the value that you need for this ELAN.
Specifies the maximum size of an AAL-5 Service Data Unit that the LE Service can guarantee not to drop because it is too large.
Valid Values:
Default Value:
If the ELAN type is token ring, the default is 4544.
If the ELAN type is Ethernet, the default is 1516.
Valid Values: any character string of length 0 - 32 bytes
Default Value: blank
Control timeout is the period used for timing out most request/response control frame interactions.
Valid Values: An integer number of seconds in the range of 10 - 300
Default Value: 120 seconds
This is the maximum number of frames for a given unicast MAC address or route descriptor that may be sent to the BUS within a specified time period.
Valid Values: an integer number of frames in the range of 1 - 10
Default Value: 1 frame
During this period of time, the LEC will send no more than the maximum unknown frame count number of frames to the BUS for a given unicast LAN destination, and the LEC must also initiate the address resolution protocol to resolve that LAN destination.
Valid Values: An integer number of seconds in the range of 1 to 60
Default Value: 1 second
If you are using switched virtual circuits (SVCs), the LEC should release any data direct VCCs that have not been used to transmit or receive data frames for the timeout period.
Valid Values: an integer number of seconds in the range of 1 to unlimited
Default Value: 1200 seconds
This parameter sets the maximum number of times the LEC must retry an LE_ARP_REQUEST for a given LAN destination.
Valid Values: An integer number in the range of 0 to 2
Default Value: 1
This number is the maximum time that a LEC will keep an entry in its LE_ARP cache without verification of the LE_ARP relationship.
Valid Values: An integer number of seconds in the range of 10 - 300
Default Value: 300
This number is the maximum time that a LEC will maintain an entry for a non-local MAC address in its LE_ARP cache without verification of the LE_ARP relationship, as long as the Topology Change flag is true.
Valid Values: An integer number of seconds in the range of 4 - 30
Default Value: 15
This is the maximum time that the LEC expects an LE_ARP_REQUEST/LE_ARP_RESPONSE cycle to take.
Valid Values: An integer number of seconds in the range of 1 to 30
Default Value: 1 second
This is the time limit that the LEC must wait to receive LE_FLUSH_RESPONSE after the LE_FLUSH_REQUEST has been sent before taking recovery action.
Valid Values: An integer number of seconds in the range of 1 to 4
Default Value: 4 seconds
The LEC can assume that a frame sent to the BUS has been either discarded or delivered to the receiver after this amount of time.
Valid Values: an integer number of seconds in the range of 1 to 8
Default Value: 6 seconds
Select Best Effort whenever possible.
Valid Values:
Default Value: Best Effort
The LEC uses this parameter when establishing the Multicast Send VCC. for reserving bandwidth on the VCC to the BUS. It specifies the average rate to be used for forward and backward sustained cell rate to be requested by LEC when setting up multicast send VCC when using reserved bandwidth connections.
Both the setting and the default depend on the parameter specified for Multicast Send VCC type as described in Multicast Send VCC Type.
Valid Values
The LEC uses this parameter when reserving bandwidth on the Multicast Send VCC. It specifies the peak rate to be used for the forward and backward sustained cell rate to be requested by LEC when setting up multicast send VCC when using reserved bandwidth connections.
Both the setting and the default depend on the parameter specified for multicast send VCC type as described in the Multicast Send VCC type.
This is the time period in which data or a READY_IND message is expected from a Calling Party.
Valid Values: an integer number of seconds in the range of 1 to 10
Default Value: 4 seconds
This is maximum number of queued frames per LE_ARP cache entry.
Valid Values: an integer number in the range of 0 - 10
Default Value: 5
This is the number of entries in the LE_ARP cache.
Valid Values: an integer number in the range of 10 - 1024
Default Value: 10
This is the signalling parameter used when establishing best-effort multicast send connections.
Valid Values: an integer number in the range of 10 - device line speed
Default Value: 155000 Kbps
This is the maximum number of times a LE_CONFIG_REQUEST should be sent to the LECS.
Valid Values: an integer number in the range of 0 -5
Default Value: 3
Valid Values: Enable or Disable
Default Value: Disable
