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.
