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 with the MAXBANDWIDTH parameter.
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.
