Configuring Assured
Bandwidth
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.
Configuration
Prerequisites
■ 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
Configuration Procedure
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.
Configuration Example
■ 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.
