Data Center Bridging Commands
903
User Guidelines
NOTE: This command is only available on N40xx series switches.
This command specified in Interface Configuration mode only affects a
single interface, whereas the Global Configuration mode setting is applied to
all interfaces. The Interface Configuration mode command is only available
on the N4000 series switches.
Each
bw-x value is a percentage that ranges from 0 to 100 in increments of 1.
All n bandwidth values must be specified with this command, and their
combined sum must not exceed 100%. The default minimum bandwidth
value for each TCG is 0, meaning no bandwidth is guaranteed (best effort) In
order to better accommodate bursty traffic, it is recommended that the sum
of the minimum bandwidths configured be much less than 100%.
If the value of any bw-x minimum bandwidth parameter is specified as greater
than the current maximum bandwidth value for the corresponding TCG,
then its corresponding maximum bandwidth automatically increases the
maximum to the same value. Min-bandwidth may be configured manually by
the operator on manual and auto-configuration ports. If the port is an auto-
configuration port, the weights received via ETS TLVs are taken into account
by the scheduler along with the min-bandwidth parameters supplied by the
operator.
Refer to the
cos-queue min-bandwidth command for information regarding
scheduling frame for transmission across TCGs.
Example
The following example demonstrates how to reserve the minimum bandwidth
percentage for TCG 1 and 2 to 25% each and reserve the remaining
bandwidth for TCG 0.
console(config)# traffic-class-group min-bandwidth 50 25 25
traffic-class-group strict
Use this command in Global Config or Interface Configuration mode to
activate the strict priority scheduler mode for each specified TCG.
Use the
no form of the command to return the TCGs to the default weighted
scheduler mode.
