The function of assured bandwidth is to provide the maximum available
bandwidth and minimum assured bandwidth for the specified traffic to get the
corresponding service.
ACL rules used for traffic identifying are defined. Refer to "Choosing ACL
■
Mode for Traffic Flows" on page 639 for defining ACL rules
The parameters for the assured bandwidth are specified
■
The ports that need this configuration are specified

acl-rule: Applied ACL rules which can be the combination of various ACL rules.
Type-A I/O Modules' way of combination is described in Table 540, and
non-type-A I/O Modules' 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 of the switch is accessed into the network segment 10.1.1.1/24.
■
Enable the function of assured bandwidth for traffic from the network
■
segment 10.1.1.1/24.
Set the parameters as follows: the minimum assured bandwidth is 64 kbps, the
■
maximum available bandwidth is 128 kbps, and the weight of bandwidth is 50.
