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:
Command
Raisecom(config-
gigaethernet1/1/port)#rate-limit
{ ingress | egress } cir
cbs-value
cbs
Raisecom(config)#rate-limit mode
{ l1 | l2 }
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.

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.
