LANE Configuration Tasks
You can use ATM address templates in many LANE commands that assign ATM addresses to LANE
components or that link client ATM addresses to emulated LANs. Using templates can greatly simplify
the use of these commands.
Note E.164-format ATM addresses do not support the use of LANE ATM address templates.
LANE ATM address templates can use two types of wildcards: an asterisk (*) to match any single
character, and an ellipsis (...) to match any number of leading or trailing characters.
In LANE, a prefix template explicitly matches the prefix but uses wildcards for the end station interface
(ESI) and selector fields. An ESI template explicitly matches the ESI field but uses wildcards for the
prefix and selector fields. Table 14-1 shows how the values of unspecified digits are determined when
an ATM address template is used.
Rules for Assigning Components to Interfaces and Subinterfaces
The following rules apply to assigning LANE components to the major ATM interface and its
subinterfaces:
•The LECS always runs on the major interface.
The assignment of any other component to the major interface is identical to assigning that
component to the 0subinterface.
•The server and the client of the same emulated LAN can be configured on the same subinterface.
•Clients of two different emulated LANs cannot be configured on the same subin terface.
•Servers of two different emulated LANs cannot be configured on the same subinterface.
Note On the ATM switch router, LANE components can be configured only on the multiservice route
processor interface or on one of its subinterfaces.

Unspecified Digits In Value Is
Prefix (first 13 bytes) Obtained from ATM switch router via Integrated Local
Management Interface (ILMI)
ESI (next 6 bytes) Filled with the slot MAC address1 plus
•0—LANE Client (LEC)
•1—LANE Server (LES)
•2—LANE broadcast-and-unknown server (BUS)
•3—LANE Configuration Server (LECS)
1. The lowest MAC addresses in the pool addresses assigned to the ATM interface plus a value that indicates the
LANE component.
Selector field (last 1
byte)
Subinterface number, in the range 0 through 255
