Configuring Port Speed
The port speed on an interface, combined with the rate mode, determines the amount of shared resources available to the ports in the port group on a 48-port or 24-port 4-Gbps Fibre Channel switching module. Especially in the case of dedicated rate mode, the port group resources are reserved even though the bandwidth is not used.
To configure dedicated bandwidth on an interface using Fabric Manager, follow these steps
- Select a switch from the Fabric pane, or select a group of switches (SAN, fabric, VSAN) from the Logical Domains pane.
- Expand Switches, expand Interfaces and select FC Physical from the Physical Attributes pane.
- Scroll until you see the row containing the switch and port you want to configure.
- Select auto, 1Gb, 4Gb, or autoMax2G from the Speed Admin column.
The auto parameter enables autosensing on the interface. The autoMax2G parameter enables autosensing on the interface with a maximum speed of 2 Gbps.
Note If you change the port bandwidth reservation parameters on a 48-port or 24-port 4-Gbps Fibre Channel switching module, the change affects only the changed port. No other ports in the port group are affected.
- Click the Apply Changes icon.
