Hardware bypass switchover
When you switch from normal operation to hardware bypass, or back to normal operation, you may experience several seconds of interrupted traffic. During this time, connections may drop.
Connection interruption factors
Several factors can affect the length of the traffic interruption during hardware bypass switchover.
-
Copper port auto-negotiation
-
Behavior of the optical link partner such as how it handles link faults and de-bounce timing
-
Spanning tree protocol convergence
-
Dynamic routing protocol convergence
You may also experience dropped connections due to application identification errors when analyzing connections midstream after the returning to normal operations.
