11-48 Quality of Service (QoS) Commands

Interface This displays the slot/port of the interface. If displaying the glo-
bal configuration, this output line is replaced with a Global Con-
fig 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 num-
ber 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 spe-
cific p value 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.
show interfaces tail-drop-threshold
This command displays the tail drop threshold configuration for each supported drop precedence
level of each queue for the specified interface. The slot/port parameter is optional and is only valid
on platforms that support independent per-port class of service mappings. If specified, the class-
of-service tail drop configuration of the interface is displayed. If omitted, the most recent global
configuration settings are displayed.
