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. 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 traffic 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 in
option 4, Exceed Remark Value. 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.

A new DSCP value can be set at all three levels:
flow group, traffic class, and policy. A DSCP value
specified in a flow group overrides a DSCP value
specified at the traffic class or policy level. A DSCP
value specified at the traffic class level is used only
