If the traffic is below the maximum bandwidth,
unused tokens will accumulate in the bucket since
the actual bandwidth falls below the specified
maximum. The unused tokens will be available for
handling excess traffic should the traffic exceed the
maximum bandwidth. Should an increase in traffic
continue to the point where all the unused tokens
are used up, packets will be discarded.
Unused tokens accumulate in the bucket until the
bucket reaches maximum capacity, set by this
parameter. Once the maximum capacity of the
bucket is reached, no extra tokens are added. The
range is 4 to 512 Kbps.
This parameter must be used with the
MAXBANDWIDTH parameter. Specifying a token
bucket size without also specifying a maximum
bandwidth serves no function.
priority Specifies the priority value in the IEEE 802.1p tag
control field that traffic belonging to this traffic class
is assigned. Priority values range from 0 to 7 with 0
being the lowest priority and 7 being the highest
priority. Incoming frames are mapped into one of
eight Class of Service (CoS) queues based on the
priority value.
If you want the packets to retain the new value
when they exit the switch, use the
REMARKPRIORITY parameter.
A new priority can be set at both the flow group and
traffic class levels. If it is set in both places, the
value in the flow group overrides the value in the
traffic class.
remarkpriority Replaces the user priority value in the packets with
the new value specified with the PRIORITY
parameter. This parameter is ignored if the
PRIORITY parameter is omitted or set to NONE.
Options are:
yes, on, true Replaces the user priority value in
the packets with the new value
specified with the PRIORITY
parameter.
no, off, false Does not replace the user priority
value in the packets with the new
value specified in with the PRIORITY
