The most significant 32 bits of the bandwidth, in bits per second, that the manager desires to allocate to the traffic class as idleSlope(N). This object MUST be read or written at the same time as hm2AgentDot1qFqtssAdminIdleSlopeLs, which represents the LS 32 bits of the value, in order for the read or write operation to succeed. If SRP is supported and in operation, then the reserved bandwidth is determined by the operation of SRP, and any changes to the value of this object have no effect on the operational value of idleSlope(N). The value of this object MUST be retained across reinitializations of the management system.
