2.3.5 LR
Port rate limiting refers to limiting the total rate of inbound or outbound packets on a
port.
Port rate limiting can be implemented through token buckets. That is, if you perform
port rate limiting configuration for a port, the token bucket determines the way to
process the packets to be sent by this port or packets reaching the port. Packets can be
sent or received if there are enough tokens in the token bucket; otherwise, they will be
dropped.
Compared to TP, port rate limiting applies to all the packets passing a port. It is a
simpler solution if you want to limit the rate of all the packets passing a port.
