Dedicated Rate Mode

<a name="wp1073567"> </a><p class="pBody">
When port rate mode is configured as dedicated, a port is allocated required fabric bandwidth and related 
resources to sustain line rate traffic at the maximum operating speed configured for the port. In this 
mode, ports do not use local buffering and all receive buffers are allocated from a global buffer pool (see 
the <a href="buffers05.html">&quot;Buffer Pools&quot; topic</a>).&#160;
