Adding a B-VLAN to ECT algorithm mapping
1. From the navigation tree, select Service > VAN Fabric Manager > LAN Configuration > SPB.
2. Click the B-VLAN Plan tab.
3. In the B-VLAN plan list, click Add.
4. Map a B-VLAN ID to an ECT algorithm index:
{
B-VLAN ID—Enter the B-VLAN ID. Make sure the B-VLAN plan has not included this B-VLAN
yet.
{
ECT index—Select an ECT algorithm index from 1 to 16.
5. Click OK.
Importing B-VLAN ID to ECT algorithm mappings from devices
1. From the navigation tree, select Service > VAN Fabric Manager > LAN Configuration > SPB.
2. Click the B-VLAN Plan tab.
3. Click Import from Devices.
The page displays all B-VLAN ID to ECT index mappings on SPB devices that are imported to the
SPB module.
4. Select mappings.
5. Click OK.
The SPB module does not import mappings for a B-VLAN if the B-VLAN plan already contains the
B-VLAN ID.
Remapping a B-VLAN to an ECT algorithm index
To move traffic from an overloaded path to a path that has less traffic, you have the following methods:
• Change B-VLAN to ECT algorithm mappings. This method enables you to move all traffic of a
B-VLAN from one path to another. The B-VLAN's traffic is disrupted before you complete B-VLAN to
ECT algorithm remapping across the SPB network.
• Perform ECT migration (see " Performing ECT migration "). ECT migration provides more granular
traffic control than B-VLAN to ECT algorithm remapping. This method minimizes traffic loss.
To remap a B-VLAN to an ECT algorithm index:
1. From the navigation tree, select Service > VAN Fabric Manager > LAN Configuration > SPB.
2. Click the B-VLAN Plan tab.
3. Click the Modify icon for the target B-VLAN ID.
4. In the dialog box that appears, select a new ECT algorithm index.
5. Click OK.
A confirmation dialog box appears.
6. Click Yes to immediately deploy the B-VLAN to ECT algorithm mapping to devices. Click No to
save the B-VLAN to ECT algorithm mapping only in VFM.
