SET QOS TRAFFICCLASS
Syntax
set qos trafficclass= value [description=” string ”]
[exceedaction=drop|remark]
[exceedremarkvalue=
value |none] [markvalue= value |none]
[maxbandwidth= value |none] [burstsize= value |none]
[priority= value |none]
[remarkpriority=yes|no|on|off|true|false]
[flowgrouplist=

Parameters
trafficclass Specifies an ID number for the flow group. Each
flow group on the switch must be assigned a unique
number. The range is 0 to 511. The default is 0. This
parameter is required.
description Specifies a description for the traffic class. The
description can be from 1 to 15 alphanumeric
characters. Spaces are allowed. If the description
contains spaces, it must be enclosed in double
quotes. Otherwise, the quotes are optional. This
parameter is optional, but recommended. Names
can help you identify the traffic classes on the
switch.
exceedaction Specifies the action to be taken if the flow group of
the traffic class exceeds the maximum bandwidth,
specified in option 6. There are two possible exceed
actions, drop and remark. If drop is selected, traffic
exceeding the bandwidth is discarded. If remark is
selected, the packets are forwarded after replacing
the DSCP value with the new value specified with
the EXCEEDREMARKVALUE parameter. The
default is drop.
exceedremarkvalue Specifies the DSCP replacement value for traffic
that exceeds the maximum bandwidth. This value
takes precedence over the DSCP value set with the
MARKVALUE parameter. The range is 0 to 63. The
default is 0.
markvalue Specifies a replacement value to write into the
DSCP (TOS) field of the packets. The range is 0 to
63.
