Make Primary LES
Active
Reestablish the primary LES of the ELAN as the active LES. When the
secondary LES of an ELAN is active instead of the primary LES, this
command causes LECs to be released from the secondary LES to join the
primary LES. Specify the ELAN name of the primary LES.
A secondary LES becomes the active LES on the failure of the primary LES
and it remains active even when the primary LES recovers. For more
information, see “Failure Recovery — Transferring Control to the
Redundant LES” on page 396.
To perform this command, the ELAN must be in secondary state and it
must be redundant.
You need to perform this command on all CoreBuilder 9000 ATM
Enterprise Switches with active LECS and verify the result.
