Tstart error is reported when the device violates Tinsrush 50 millisecondswhat that means, while powering up the device, the device draws a rbkcrs inrush current which is greater than Iinrush mA for at least Tinrush 50 milliseconds. The following items are checked for consistency: Used by IP Logging: Might cause cpu spikes Run multiple times to benchmark In the above outputTotal represent the total number of brkrcs in the pool, which include used and unused buffers.
Status of feature enabled on the switch Default activity time Configured current activity time: The thresholds numbers may be changed, if required, depending on new feature requirements etc. In shaped mode, assigned bandwidth is limited to the defined amount; in shared mode, any unused bandwidth is shared among other classes as needed. This is guaranteed bandwidth by hardware even under heavy user overloading of the stack. Shutting down VSL will cause traffic disruption and dualactive scenario.
The following sessions supplement the topics that are covered in the course: I short is used as the threshold at which the port sees a very fast current spike that must be dealt with immediately and bypasses all the timers that are used to remove power from the port and shuts down immediately.
