sub-class (htb)
Overview Use this command to configure a hierarchy token bucket (HTB) sub-class within an
existing class.
Use the no variant of this command to delete an existing sub-class under the
current class.
Syntax
sub-class <class-name> [cir < committed-rate >] [pir < peak-rate >]
[bc < 1-100000000 >] [be < 1-100000000 >] [preference < 0-7 >]
[queue-length < 2-65536 >] [set-dscp < dscp-value >] [red-curve
<red-curve-name> ]
sub-class <class-name> [cir < committed-rate >] [pir < peak-rate >]
[bc < 1-100000000 >] [be < 1-100000000 >] [preference < 0-7 >]
sub-sub-class-policy htb
no sub-class <class-name>
Default BC and BE are assigned suitable values proportional to the CIR and PIR respectively
and are larger that the MTU. PIR defaults to the CIR. Preference defaults to 7 and
the queue length default to 1000 if the class is a leaf.
Mode Traffic-Control Class for an HTB sub-class policy.
Parameter Description
<class-name>
Name of the class.
cir <committed-rate>
Set the Committed Information Rate (CIR) for the queue. Specified in
kbit/mbit/gbit per second, 1kbit-100gbit.
This parameter is compulsory when creating a new sub-class. When
editing an existing sub-class, this parameter is optional.
pir <peak-rate>
Set the Peak Information Rate (PIR) for the queue. This is the rate of the
queue under peak conditions. Specified in kbit/mbit/gbit per second,
in the range 1kbit-100gbit.
bc <1-100000000>
Set the Committed Burst size (BC). This is the burst allowed above the
CIR, sent at the PIR rate.
be <1-100000000>
Set the Excess Burst size (BE). This is the burst allowed above the PIR,
sent at the maximum rate.
preference <0-7>
Set the preference for a class to receive spare bandwidth (highest is 7).
queue-length <2-65536>
Set the maximum queue length in packets.
set-dscp <dscp-value>
Set the DSCP value to apply to the packets.
red-curve <red-curve-name>
Apply a random early discard template with the sub-class and enter
the name of the red curve template to apply.
sub-sub-class-policy
Specify that the sub-class will contain sub-sub-classes.
htb
Sub-sub-classes will use the Hierarchy Token Bucket (HTB) queueing
discipline.
