B Check that the secondary LEC conﬁguration status is “Operational” and

the state is “Current”.

This means that the secondary LAN Emulation Services have

successfully taken over from the failed primary services.

If the secondary LEC conﬁguration status is “Not operational”,

troubleshoot it in the same way as the primary LEC conﬁguration.

C Check that both source and destination systems have joined the same

secondary LES/BUS ATM address.

The secondary LES/BUS ATM address indicates the secondary ELAN

and must be the same on both end systems. Otherwise, they will switch

over to different ELANs if the primary services fail.

Check that any Access Control rules conﬁgured in the secondary LECS

conﬁguration ﬁle do not prevent the source and destination systems from

joining the ELAN. See “Checking ELAN Access Control Rules Deﬁnitions

on LECS” on page 244 for details.

D If you have conﬁgured a secondary LECS, check that the secondary

LECS ATM address is displayed correctly and is different from the

primary LECS ATM address.

If you have conﬁgured a secondary LECS and the secondary LECS ATM

address is the same as the primary LECS ATM address, then run SAM

and reconﬁgure it.
