4.3.6.2.3 Configuring Rate Limiting for User-defined Applications
Besides the pre-defined applications (refer to Section 4.3.6.2.2), you can also
configure other applications that can send packets to the NPU.
Run the following command to configure rate limiting for a user-defined
application.
npu(config-ratelmt)# set rate-limit <user-defined-app> {[srcport
<port_num>] [dstport <port_num>] [protocol <protocol_num>] [srcaddr
<ip_addr>] [dstaddr <ip_addr>] [ethertype <protocol_num>]}
<rate-Kbps>
In the above command, it is recommended that you configure at least one of the
following parameters. The more parameters you configure, the higher the
granularity of the rate limiting definition for that application.
 L4 source port
 L4 destination port
 L3 protocol field
 Source IP address
 Destination IP address
 L2 protocol type field
