218 CHAPTER 8: ACL CONFIGURATION
Table 241 Configure the Queue Scheduling Algorithm
By default, the Switch uses the WRR algorithm.
For details about the command, refer to the Command Reference Manual.
Setting Traffic Limit Traffic limit refers to rate limit based on traffic. If the traffic threshold is exceeded,
corresponding measures will be taken, for example, dropping the excessive
packets or re-defining their priority levels.
Perform the following configurations in the Ethernet Port View.
Table 242 Setting Traffic Limit
You should first define an ACL before this configuration task.
The granularity of traffic limit is 64kbps. If the target-rate user input is in ( N*64,
(N+1)*64], in which N is a natural number, Switch automaticaly sets (N+1)*64 as
the parameter value.
This configuration achieves rate control for those packets that match the ACL. If
the traffic rate threshold is exceeded, corresponding measures will be taken, for
example, dropping excessive packets.
Setting Line Limit Line limit refers to rate limit based on the port, that is, limiting the total rate at the
port. The granularity of line rate is 64 kbps.
Perform the following configurations in the Ethernet Port View.
Table 243 Setting Line Rate
Relabeling Priority Level This configuration re-labels priority level for the packets that match ACL. The new
priority label can be put in the priority domain in the header.
