Configuring the Internal Forwarding Resource Allocation Mode

Configuring the Internal Forwarding Resource Allocation Mode

Context

A switch completes internal forwarding using limited resources. An S9306 or S9312 dynamically allocates internal forwarding resources to LPUs based on LPU types by default. A standalone switch or a CSS system has a total of 64 internal forwarding resources. In dynamic resource allocation mode, a standalone switch not running the CSS function provides 54 internal forwarding resources for LPUs, and a standalone switch running the CSS function or a CSS system provides 46 internal forwarding resources for LPUs. In this mode, some LPUs occupy a large number of internal forwarding resources. Therefore, if the CSS function is enabled on a switch, allocatable internal forwarding resources may be insufficient for LPUs. In this case, LPUs not allocated internal forwarding resources or allocated insufficient internal forwarding resources fail to register and cannot provide services.

The static resource allocation mode prevents this problem. When this mode is configured, the system allocates only two internal forwarding resources to each LPU, regardless of the LPU type.

NOTE:

Only the S9306 and S9312 support the configuration of the internal forwarding resource allocation mode. The S9300E supports only the configuration of the static resource allocation mode for LPUs.

If the CSS function is not enabled on the switch, the internal forwarding resources are sufficient and you do not need to configure the static resource allocation mode.

When the static resource allocation mode is used, SA series LPUs of the cannot register with the system.

Procedure

  1. (Optional) Run display system-resource-mode configuration

    The resource allocation mode configured for LPUs is displayed.

  2. Run system-view

    The system view is displayed.

  3. Run assign system-resource-mode static

    The static resource allocation mode is configured. In this mode, the system allocates only two internal forwarding resources to each LPU, regardless of the LPU type.

    By default, the S9300 dynamically allocates internal forwarding resources to LPUs based on LPU type.
