2. Highlight a discovered DCB switch from the Available Switches list, and click the right arrow
button to move the switch to the Selected Switches list.
3. Highlight the selected switch and click OK to start the configuration.
The running configuration is saved to the selected switch, effective on the next system startup.
If you restore the DCB switch using the Restore Switch Configuration dialog box, you are
prompted to select one of two restoration methods:
•
As the running configuration and reboot
ATTENTION
Rebooting a switch connected to a fabric will stop all traffic to and from the switch. All ports
on the switch will become inactive until the switch comes back online.
•
As the startup configuration (no reboot)
For instructions on how to restore a saved switch configuration, refer to the section “Adaptive
backup” in the “Device Configuration” chapter.
DCB configuration management
Depending on the platform, the DCB switch has one of the configurations shown in Table 60 .
You must configure DCB interfaces and ports differently than you configure Fibre Channel ports to
effectively use the converged network features.
For example, priority-based flow control (PFC) and Enhanced Transmission Selection (ETS) are the
two QoS policy enhancements you must configure to create a lossless Ethernet. You then use DCBX
protocol on DCB-enabled devices to exchange configuration information.
The DCB ports of FOS DCB devices are categorized into two types:
•
External ports - The eight external ports are the same as the original 10 Gbps Ethernet DCB
ports. The default name in the device tree is ExT <slot>/<port>.
•
Internal ports - The default name for the 12 or 14 internal ports is InT <slot>/<port>.
802.1x, LAG configuration, and Spanning Tree Protocol (STP) are not supported on internal
ports.
