acl-rule: Applied ACL rules which can be the combination of various ACL rules.
The way of combination is described in Table 541.
n
Only type-A I/O Modules support the configuration above.
■
Only the rules with the permit action can be properly applied to the hardware.
■
Ethernet 2/0/1 is accessed to the network segment 10.1.1.1/24.
■
Perform the RED queue scheduling algorithm for all the inbound traffic from
■
10.1.1.1/24
Set the parameters as follows: the packets are dropped at random when the
■
queue length exceeds 64 KB, all packets are dropped when the queue length
exceeds 128 KB, and the drop probability is 20%.
