Setting Up the Database for Restricted-Membership ELANs

Those client database entries specify which clients are allowed to join the ELAN. When a client requests to

join an ELAN, the LECS consults its database and then assigns the client to the ELAN specified in the

LECS's database.

When clients for the same restricted-membership ELAN are located in multiple switch ATM interfaces,

each client's ATM address or MAC address must be linked explicitly with the name of the ELAN. As a

result, you must configure as many client entries as you have clients for ELANs in all the switch ATM

interfaces. Each client will have a different ATM address in the database entries.

To configure restricted-membership ELANs in the LECS database, use the following commands beginning

in global configuration mode:

Purpose

Enters database configuration mode for the LANE database that you specify.

Binds the name of the first ELAN to the ATM address of the LES/BUS for that ELAN

in the configuration database.

If you are configuring SSRP, repeat this step with the same ELAN name but with

different server ATM addresses for each additional server for the same ELAN. The

index determines the priority. The highest priority is 0.

Binds the name of the second ELAN to the ATM address of the LES/BUS in the

configuration database.

The index determines the priority. The highest priority is 0.

Repeat this step, providing a different name and a different ATM address, for each

additional ELAN.

Assigns a segment number to the first emulated Token Ring LAN in the configuration

database.

The segment number you specify for the local-seg-id keyword must be identical to the

ring number of the TrCRF. The set vlaninterface configuration command assumes that

any ring number you enter is in hexadecimal. The name elan-name local-seg-id

segment-number LANE database configuration command assumes that any value you

enter for the local-seg-id keyword is in decimal unless you enter it explicitly in

hexadecimal.
