7. Test the Layer 2 Failover operation
In our reference architecture, ports 1 - 4 on the ACC-1 and ACC-2 access switches are
the uplink ports to AGG-1 and AGG-2 switches.
We shut down two ports out of four on an access switch and verify that the controlled port
(port 7 connected to SRV-1) is automatically disabled.
a. Shut down two uplink ports.
Run shutdown to manually disable the ports and see the messages related to the
failover operation (Example 5-86).
Example 5-86 Manually disable monitored ports
