Trigger a Failover

You can simulate a link failure by shutting down one of the switch ports. This example shuts down port 16.

1. Shut down a switch port.

   SEFOS# configure terminal
   SEFOS(config)# interface extreme-ethernet 0/16
   SEFOS(config-if)# shutdown
   SEFOS(config-if)# end
   

2. After a few seconds, examine the SLB-L2 output.

   SEFOS# show slb l2
    
   L2 SLB Group #1
   Failover Method: Failover to All ports
    
   Members:
   Port   State     Comments
   ====   =====     =================
    15    ACTIVE
    16    FAILED     Failover to All ports
    17    ACTIVE
    18    ACTIVE
   

   This output shows that port 16 has failed. The port's state changed from active to failed. The traffic hashed to the server for port 16 will be rehashed to all remaining active ports.
