ringlet1: Configures the reserved bandwidth or rate limit for the node on Ringlet1.
value: Proportion of the bandwidth reserved on the node for class A0 service in the total
bandwidth, with the step length of 1 and default value of 0, or the proportion of the
bandwidth reserved on the node for class A1, class B-CIR and class C services in the
total bandwidth, with the step length of 1 and default value of 0.
Description
Use the rpr rate-limit command to configure rate limit for class A, class B-CIR, class C
and class B-EIR services on the local node. Use the undo rpr rate-limit command to
restore rate limit to the default value. When the rate exceeds this limit, back pressure
will occur.
Note: The total reserved bandwidth for all nodes on a ring must not exceed the ring
bandwidth.
