cos-queue min-bandwidth

Use the cos-queue min-bandwidth command in either Global Configuration
mode or Interface Configuration mode to specify the minimum transmission
bandwidth for each interface queue. To restore the default for each queue's
minimum bandwidth value, use the no form of this command.
Syntax
cos-queue min-bandwidth
no cos-queue min-bandwidth
bw-0 — Specifies the minimum transmission bandwidth guarantee for an
•
interface. You must specify as many bandwidth parameters as there are
COS queues (bw-0 through bw-n). (Range: 0–100 in increments of 5)
Default Configuration
By default, all CoS queues are configured with a 0% minimum bandwidth
guarantee.
Command Mode
Global Configuration mode or Interface Configuration (gigabitethernet,
port-channel, tengigabitethernet
User Guidelines
The maximum number of queues supported per interface is seven. It is
recommended that the operator avoid the use of queue 5-7 in order to avoid
conflicts with inter- and intra-network control traffic.
In order to better accommodate bursty traffic, it is recommended that the
sum of the configured min-bandwidths be much less than 100%. Configuring
the minimum bandwidths such that they sum to 100% effectively locks the
scheduler such that bandwidth sharing by lower priority queues cannot be
accommodated under congestion conditions.
