Set the Data Center Bridging VLAN ID
To set the DCB VLAN ID for the rst time:
1. Click GroupGroup Conguration.
2. Click the Advanced tab.
3. Enter the DCB VLAN ID in the VLAN ID eld; it must be a value from 0 to 4095. This value must be the same as the VLAN ID
congured in the switch for use by the iSCSI SAN. Values 0 and 1 are not recommended.
NOTE:
The VLAN IDs on the switch must match the VLAN you specify on the group. The ports on the switch need to allow
both the old VLAN (which usually implies a VLAN ID of 0 if none has been set) and the new VLAN ID or all VLANs
(trunk mode) to enable the group to communicate with the switch.
All group members must be 10Gb arrays and be active.
You can also specify the DCB VLAN ID through the CLI using the grpparams dcb def-vlan-id command. See the
Dell
EqualLogic Group Manager CLI Reference Guide
for more information.
Change the Data Center Bridging VLAN ID
If your group’s DCB VLAN ID has been changed from the default value of 2, you must congure the group to use it.
NOTE:
All group members must be active.
This procedure requires modifying the conguration of third-party products. See the documentation for your switches for
detailed instructions on these tasks.
1. Set the switch ports used by group members to allow both the old and new VLAN IDs.
2. Bridge the old and new VLANs either by modifying switch settings or by creating an untagged access port for each VLAN and
bridging the connections using the appropriate cable.
3. Set the VLAN ID in the group:
a. Click GroupGroup Conguration.
b. Click the Advanced tab.
c. In the Network Management panel, enter the new VLAN ID in the VLAN ID eld. The value must be from 0 to 4095.
4. Recongure iSCSI initiators to use the new VLAN ID.
5. Unbridge the old and new VLANs.
6. (Optional) Modify switch ports so that the old VLAN ID is no longer allowed.
Monitor Data Center Bridging Statistics and Conguration
1. Click Group.
2. Expand Members and then select the group member.
3. Click the Network tab.
4. In the IP Conguration panel, select a network interface.
5. The Switch Information section indicates the LLDP state of the switch connected to the interface.
6. In the Activities panel, click DCB Details to open the dialog box.
NOTE: The DCB Details link appears dimmed if the member does not support DCB.
