Command Reference
qos gts
Purpose Use the qos gts command to set shaping parameters for all or a specified type of
traffic and perform traffic shaping.
Use the
undo qos gts command to remove the shaping configuration for all or a
specified type of traffic.
Syntax qos gts { any | acl acl-number } cir committed-information-rate [ cbs
committed-burst-size [ ebs excess-burst-size [ queue-length
queue-length ] ] ]
undo qos gts { any | acl acl-number }
Parameters any
Performs TS on all the IP packets.
acl acl-number
Performs traffic shaping of packets matching the ACL,
with acl-number being the ACL number in the range
of 2000 to 3999.
cir
committed-information-rat
CIR, in the range 8000 to 155,000,000 bps.
cbs committed-burst-size
CBS, in the range 15,000 to 155,000,000 bits. When
the CIR value is less than 30,000, the default CBS value
is 15,000; when the CIR value is greater than 30,000,
the default CBS value is half of the CIR value.
ebs excess-burst-size
EBS, in the range 0 to 155000000 bits. It defaults to 0,
that is, only one token bucket is used for policing.
queue-length queue-length
The maximum length of the buffer, in the range of 1 to
1024. By default,
queue-length is 50.
Example Configure traffic shaping for the packets that conform to ACL rule 2001 at the
Ethernet6/0/0 interface. The normal traffic is 38400 bps. The burst size, twice of the
normal traffic, is allowed at the first time. Then packets are normally transmitted
when the traffic is less than or equal to 38400 bps. When the rate is larger than
38400 bps, packets will be added to the buffer queue, which is 100 long.

Description qos gts acl is used to set shaping parameters for the packets that conforms to
certain ACL. Different ACLs can be used to set shaping parameters for different
packets.
