7.6.3.4 Rate-limit
You can configure the rate limit in kbps unit for the classified packets and control the
bandwidth. To set the bandwidth of classified packets in specified policer, use the follow-
ing command.
Command Mode Description
rate-limit BANDWIDTH Policer
Sets the bandwidth for classified packets belonging to
specified policer (unit: kbps)
Rate limiting is able to use a token-bucket algorithm of metering. If some traffic exceeds
the rate limit because of its burst size, you can control burst capability of incoming or out-
going traffic by the token bucket size. The largest burst source can send into the network
is roughly proportional to the size of the bucket. Thus, you can reduce the token bucket
size manually to decrease the burst size of traffic. To configure the size of a token bucket
per port or queue of port, use the following command.
Command Mode Description
qos max-bucketSize port
{ egress | ingress } PORTS <12-
16380>
Sets the size of a token bucket to specified port by its
direction (unit: kbps).
12-16380: the range of token bucket size in steps of 4
(default: 16 kbps)
qos max-bucketSize port-queue
PORTS queue <0-7> <12-16380>
Global
Sets the size of a token bucket to a queue of specified
port. (unit: kbps)
0-7: queue number
12-16380: the range of token bucket size in steps of 4
