acl-rule: Applied ACL rules which can be the combination of various ACL rules. Type-A
LPUs’ way of combination is described in
Table 1-9, and non-type-A LPUs’ way of
combination is described in
Table 1-10.
 Note:
z Only type-A LPUs support the configuration above.
z Only the permit rules in ACLs can be properly applied to the hardware.
1.12.3 Configuration Example
z A switch is connected to 10.1.1.1/24 network segment through its Ethernet 2/0/1
port.
z Enable the guaranteed bandwidth feature for traffic from the network segment
10.1.1.1/24.
z Set the parameters as follows: the minimum guaranteed bandwidth is 64 kbps, the
maximum available bandwidth is 128 kbps, and the weight of bandwidth is 50.
