Set ILEC

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.

  1. Select the ESI address that the LEC will use as its primary ATM address.

    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.

  2. Select the MAC address that the LEC will use.

    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.

  3. Enter a selector byte value in hex.

    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.

  4. Enter the ATM address of the LE Server this client will use.

    Valid Values: any ATM address

    Default Value: none

  5. Enter the MAC cache size.

    This value specifies the maximum number of MAC entries that the LEC caches.

    Valid Values: 5 - 1024

    Default Value: 32

  6. Enter the MAC cache aging period.

    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

  7. Enter the Route Descriptor cache size.

    This specifies the maximum number of route descriptor entries that the LEC caches.

    Valid Values: 5 - 1024

    Default Value: 32

  8. Enter the Route Descriptor cache aging period.

    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

  9. Enter the LES registration interval.

    This specifies the frequency (in seconds) that the LEC sends registration messages to the LES.

    Valid Values: 30 - 240

    Default Value: 60

  10. Enter the LES registration retry count.

    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

    Enter the LES keep alive count.

    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

  11. Enter the LE forward peakrate.

    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

  12. Enter the LE backward peakrate.

    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

  13. Enter the LES registration retry count.

  14. Enter the maximum data frame size.

    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.

  15. Indicate whether to enable Packet Tracing.

    Valid Values: Enable or Disable

    Default Value: Disable
