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.
If you do not use the adapter address as the LE client's MAC address, enter the LE client's MAC address.
Valid Values: any valid MAC address.
Default Value: 00.00.00.00.00.00
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.
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.
Valid Values: any ATM address
Default Value: none
This value specifies the maximum number of MAC entries that the LEC caches.
Valid Values: 5 - 1024
Default Value: 32
This specifies the amount of time (in seconds) after which MAC addresses are aged out of the cache, if they have not been refreshed.
Valid Values: 1 - 300
Default Value: 60
This specifies the maximum number of route descriptor entries that the LEC caches.
Valid Values: 5 - 1024
Default Value: 32
This specifies the amount of time (in seconds) after which entries are aged out of the route descriptor cache, if they have not be en refreshed.
Valid Values: 1 - 300
Default Value: 60
This specifies the frequency (in seconds) that the LEC sends registration messages to the LES.
Valid Values: 30 - 240
Default Value: 60
This value sets the retry count. This is the naximum number of times that the LEC retries an LE_ARP_REQUEST for a specific frame' s LAN destination.
Valid Values: 2 - 10
Default Value: 3
This value specifies the number of times that the LEC sends a
registration message without requiring a response from the LES.
Valid Values: 5 - 50
Default Value: 10
This value specifies the maximum data rate (forward), in Kbps, of the ATM
device for all LAN emulation connections.
Default Value: data rate of device
This value specifies the maximum data rate (backward), in Kbps, of the ATM device for all LAN emulation connections.
Valid Values: 1 - maximum data rate of the ATM device
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: Enable or Disable
Default Value: Disable
