SFTOS Command Reference for the S2410, Version 2.4.1.0 283
Syntax
show interfaces random-detect slot/port
The slot/port parameter is optional. If specified, the class-of-service WRED configuration of
the interface is displayed. If omitted, the most recent global configuration settings are
displayed.

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.
WRED Minimum Threshold — The WRED minimum 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.
WRED Maximum Threshold — The WRED maximum 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.
WRED Drop Probability Scale — The WRED drop probability scale factor expressed as an integer. This
value, S, specifies that one out of every (2**S) packets are dropped by WRED when the average queue
length reaches its maximum threshold value. This is a configured value.

precedence level of each queue for the specified interface.
Syntax
