If the Recovery Delay Period is Configured
If you configured a local recovery delay period for a primary ELAN
interface (see “Local Recovery” on page 93), and the interface fails, one or
both of these messages are written to the log file at the beginning of the
delay period: The Current ELAN interface status has changed to
DOWN and The Current ATM adapter status has changed to DOWN.
Then, if the interface does not come back up during the delay period,
another message is logged, as follows:
•Ifboth of the above messages are logged
—IfThe Current ELAN interface status has changed to
DOWN is logged first, then the message Current ELAN interface
is DOWN is also logged.
—IfThe Current ATM adapter status has changed to DOWN is
logged first, then the message Current ATM adapter is DOWN is
also logged.
• If only The Current ELAN interface status has changed to
DOWN is logged, then only Current ELAN interface is DOWN is also
logged.
Example for HP-UX 10.20:
------------------------ EVENT #22 -----------------------
20:09:1998:22:49:19:986 314 : The current ELAN interface status has
changed to DOWN.
ELAN interface: ela0
Waiting 20 seconds for recovery of the ELAN interface.
------------------------ EVENT #23 -----------------------
20:09:1998:22:49:36:294 315 : The current ATM adapter status has
changed to DOWN.
ATM adapter name: atm0
Waiting 20 seconds for recovery of the ELAN interface.
------------------------ EVENT #24 -----------------------
20:09:1998:22:50:22:294 305 : Current ELAN interface is DOWN.
ELAN interface name: ela0
Action : If the ATM adapter for this interface: atm0
is not DOWN verify the LAN Emulation services.
