Port Rate Modes

In Generation 2 and Generation 3 modules, you can configure the port rate modes. The port rate mode
configuration is used to determine the bandwidth allocation for ports in a port group. Two port rate
modes are supported:
•
•
In Generation 1 modules, you cannot configure the port rate modes. The mode is determined implicitly
Note
based on the port mode and line card type.

Dedicated Rate Mode—A port is allocated required fabric bandwidth to sustain line traffic at the
maximum operating speed configured on the port. For more information, see the
Mode" section on page 15-6
Shared Rate Mode—Multiple ports in a port group share data paths to the switch fabric and share
bandwidth. For more information, see the
