2. Highlight a discovered DCB switch from the Available Switches table, and click the right arrow
button to move the switch to the Selected Switches Table.
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 “Restoring a switch
configuration for a selected device” on page 251.
DCB configuration
Depending on the platform, the DCB switch has the one of the following configurations:
• For the IBM blade server:
- 14 internal 10 Gbps ports for BCH type
- 12 internal 10 Gbps ports BCHT type
- Eight external 10 Gbps DCB ports
- Eight 8-Gbps FC ports
• For the Dell embedded switch module:
- 16 10-Gbps internal ports
- Eight 10-Gbps external ports
- Four 8-Gbps FC ports
You must configure DCB interfaces and ports differently than you configure FC ports, in order 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/FC switch module for the IBM Blade Center has eight 8-Gbps FC ports and 22/20 10
Gbps Ethernet DCB ports. The DCB ports 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.
