Cisco Switch Threshold Groups Per VC Queueing Rm Hierarchical Scheduling Mode

1.3.6.1.4.1.9.10.10.1.9.3

On a Catalyst8540 MSR, the user can define Hierarchical VP-Tunnels. Each such tunnel has its own dedicated scheduler, programmed to output data at a configurable maximum rate. Therefore, the overall output of the Hierarchical VP-tunnel is rate-limited. In addition, Virtual Circuits of different service categories can traverse through such a tunnel, and each of these Virtual Circuits are guaranteed their individual contracted bandwidth agreement. This object must be set to enabled before any Hierarchical VP-tunnels can be defined on the device. Any setting of this variable requires a reload of the device to be effective. Setting this object to enabled will cause the software to initialize the additional schedulers needed by the Hierarchical VP-Tunnels. Other limited scheduler resources are therefore used by a larger number of schedulers (as compared to the case when Hierarchical Scheduling is disabled on the device). This may result in fewer number of connections passing Connection Admission Control. This object is therefore provided so that the user can make an informed decision as to whether Hierarchical Scheduling is to be used. This object is supported only on the Catalyst8540MSR platform.
