tail-drop queue-parms
Mode
Privileged Exec
Report Fields Interface — This displays the slot/port of the interface. If displaying the global configuration, this output
line is replaced with a Global Config indication.
The following information is repeated for each queue on the interface.
Queue IdQueue identification number — An interface supports n queues numbered 0 to (n-1). The
number n is platform dependent and corresponds to the number of supported queues (traffic classes).
The following information is repeated for each drop precedence level defined for the
preceding Queue ID.
Drop Precedence Level — The drop precedence level for this queue, from 1 to p. The specific pvalue is
platform-dependent.
Tail Drop Threshold — The tail drop queue threshold value for this drop precedence level, expressed in
sixteenths of the overall device queue size (e.g., 0/16, 1/16, 2/16…, 16/16). This is a configured value.
