> # Reserving Bandwidth Quickly for the 8-Gbps Module Interfaces

> ## Detailed Steps

> To quickly reserve bandwidth for all the ports in the port groups on the Generation 3 Fibre Channel modules using the Device Manager, follow these steps:

> 1. In the Device Manager window, right-click the 8-Gbps Fibre Channel module.

> 2. From the popup menu, select Bandwidth Reservation Config...
> 3. In the Bandwidth Reservation Configuration dialog box that is displayed, choose a bandwidth reservation scheme.

> Table 13-15 describes the default RateMode configuration schemes available in the Bandwidth Reservation Configuration dialog box for the 8-Gbps modules.

> Table 13-15 RateMode Configuration Schemes
> Module | Available RateMode Config Macros
> --- | ---
> DS-X9248-96K9 48-Port 8-Gbps Fibre Channel module | Dedicated 4 Gbps on the first port of each group and the remaining ports 8 Gbps shared Dedicated 8 Gbps on the first port of each group and the remaining ports 8 Gbps shared Shared 8 Gbps on all ports (initial and default settings)
> DS-X9224-96K9 24-Port 8-Gbps Fibre Channel module | Dedicated 8 Gbps on the first port of each group and the remaining ports 8G shared Shared Auto1 on all ports (initial and default settings)
> DS-X9248-48K9 4/44-Port 8-Gbps Host-Optimized Fibre Channel module | Dedicated 2 Gbps on the first port of each group and the remaining ports 4 Gbps shared Dedicated 8 Gbps on the first port of each group and the remaining ports 4 Gbps shared Shared Auto with Maximum of 4 Gbps on all ports (initial and default settings)

> 1Auto is 8 Gbps.
