Managing ELAN Clients
A client is a LEC on an ELAN. You can set up ELAN client mappings:
•
•
To enable you to map a LEC from one ELAN to another.
•
To allow only the LECs that match the ELAN client mappings to join a specific
secure ELAN. For more information about setting up a secure ELAN, see
Changing the Security of an ELAN earlier in this chapter.

ELAN client mappings are stored in the local LECS database. These mappings tell
the LECS to assign a LEC or group of LECs to a specific ELAN. In total, up to 512
mappings can be stored in the local LECS database.
An ELAN client mapping allows you to map a LEC or group of LECs to a specific

An ELAN client mapping allows you to map a LEC or group of LECs to a specific
secure ELAN based on one of the following:
•
An ATM address
•
A MAC address
•
An alias ELAN name. The alias is provided by the LEC in its configuration
request to the LECS.
request to the LECS.
The alias ELAN mapping maps the ELAN name requested by the LEC to another
ELAN. This allows the system administrator to change user ELANs at the switch.
An ATM address or an alias ELAN name mapping usually refer to a group of LECs,
whereas a MAC address mapping always refers to a specific LEC. In this way you
can create generic mappings instead of a separate mapping for each and every LEC.
Figure 16.1 shows how client mappings are used when a LEC sends a request to the
LECS to join an ELAN.
