PortRedundancyFailover in Cable Defect Scenario
In the example above, an Ethernet cable is cut or unplugged, causing the link to go down. When this event occurs, the
system, with port-mode redundancy enabled, recognizes the link down state and makes port 33/1 the active port. The
switching devices, using some port redundancy scheme, recognizes the failure and enables the port on the secondary
switch that the line card in slot 33 is connected to, allowing it to redirect and transport data.
