Step 4. Unplug the ATM cable on the adapter configured with the primary
ELAN interfaces.
If local failover has occurred correctly, the following things are true:
• The telnet connection is not broken when you disconnect the cable.
• The netstat -in command shows that the IP address has been
transferred to a secondary ELAN.
Using the example above, the netstat -in display would initially
look like this:
ela0 1500 200.128.168 200.128.169.5 3780 0 3472 78 0
ela1 1500 201.128.168 201.128.169.5 3595 0 3291 78 0
ela2 1500 202.128.168 202.128.169.5 3440 0 3133 79 0
elc0 1500 none none 12 0 0 0 0
elc1 1500 none none 12 0 0 0 0
elc2 1500 none none 12 0 0 0 0
After local recovery, the display would look like this:
ela0 1500 none none 12 0 0 0 0
ela1 1500 none none 12 0 0 0 0
ela2 1500 none none 12 0 0 0 0
elc0 1500 200.128.168 200.128.169.5 3780 0 3472 78 0
elc1 1500 201.128.168 201.128.169.5 3595 0 3291 78 0
elc2 1500 202.128.168 202.128.169.5 3440 0 3133 79 0
The secondary interfaces—not the primary interfaces—would have the
IP addresses associated with them.
If the verification procedure is not successful, see “Troubleshooting EMS
HA over ATM” on page 265.
Step 5. If, for some reason, you need to stop the monitor for the ELAN interface
resource at this time, go to the next section, “Stopping the Monitor for
the ELAN Interface Resource”.
Otherwise, you are finished with local recovery configuration, and you
can go to “Configuring EMS HA-ATM for Remote Recovery (Using
MC/ServiceGuard)” on page 130.
