Configure rate limiting based on
interface.
Raisecom(config)#rate-limit mode
{ l1 | l2 }
Configure the rate limiting mode.
By default, no interface-based rate limiting is configured.
Adopt the drop processing mode for packets on the ingress interface if they
exceed the configured rate limit.
When you configure the rate limit and burst for an interface, the burst value should
not be much greater if the configured rate limit is smaller than 256 kbit/s.
Otherwise, packets may be inconsecutive.
When the rate limit is too small, we recommend that the burst value is 4 times
greater than then rate limit. If packets are inconsecutive, reduce the burst value or
increase the rate limit.
Packets discarded due to rate limiting on the egress interface are included in
statistics about packet loss of the ingress interface.
7.6.3 Checking configurations
Use the following commands to check configuration results.
Raisecom#show rate-limit interface
Show configurations of
rate limiting on
interfaces.
Raisecom#show rate-limit interface

7.7 Bandwidth rate limiting
7.7.1 Introduction
Bandwidth rate limiting is a subfunction of QoS and is more flexible than basic QoS.
Bandwidth rate limiting has the following functions:
Ingress interface
– Bandwidth guarantee: bandwidth rate limiting implements the bandwidth service
based on interface or flow. It also supports hierarchical bandwidth guarantee and
refining bandwidth of different service flows.
– Awaring: this function determines whether to be aware of packet color when a flow
enters the bandwidth-guaranteed interface.
Egress interface
