Quality of Service (QoS) Commands
226
ProSAFE M7100 Managed Switches
If you specify the interface, the command also displays the following information.
show interfaces random-detect
This command displays the global WRED settings for each CoS queue. If you specify the
<slot/port> parameter, the command displays the WRED settings for each CoS queue on the
specified interface.
Term Definition
Queue Id An interface supports n queues numbered 0 to (n-1). The specific n value is
platf
orm-dependent.
Minimum
Bandwidth
The minimum transmission bandwidth guarantee for the queue, expressed as a percentage. A
value of 0 me
ans bandwidth is not guaranteed and the queue operates using best-effort.
This is a configured value.
Scheduler Type Indicates whether this queue is scheduled for transmission using a strict priority or a
w
eight
ed scheme. This is a configured value.
Queue
Management
T
ype
The queue depth management technique used for this queue (tail drop).
Term Definition
Interface The slot/port of the interface. If displaying the global configuration, this output line is
replac
ed with a Global Config indication.
Interface Shaping
Rate
The maximum tr
ansmission bandwidth limit for the interface as a whole. It is independent of
any per-queue maximum bandwidth value(s) in effect for the interface. This is a configured
value.
Format show interfaces random-detect [<slot/port>]
Mode Privileged EXEC
Term Definition
Queue ID An interface supports n queues numbered 0 to (n-1). The specific n value is
platf
orm-dependent.
WRED Minimum
Threshold
The c
onfigured minimum threshold the queue depth (as a percentage) where WRED starts
marking and dropping traffic.
WRED Maximum
Threshold
The c
onfigured maximum threshold is the queue depth (as a percentage) above which WRED
marks / drops all traffic.
WRED Drop
Pr
obability
The configured percentage probability that WRED will mark/drop a packet, when the queue
depth is at the maximum threshold. (The drop probability increases linearly from 0 just
before the minimum threshold, to this value at the maximum threshold, then goes to 100%
for larger queue depths).
