Port Groups

</h1>
<a name="wp1151756"> </a><p class="pBody">
Each module or switch can have one or more ports in port groups that share common resources such as 
bandwidth and buffer credits. Port groups are defined by the hardware consisting of sequential ports. For 
example, ports 1 through 6, ports 7 through 12, ports 13 through 18, ports 19 through 24, ports 25 
through 30, 31 through 36, and ports 37 through 42, 43 through 48 are the port groups on the 48-port 
8-Gbps Advanced Fibre Channel switching modules.
