Understanding Unassociated Bridges
Some switching entities might not belong to a flow domain, such as a network VLAN, a VPLS instance,
or a network pseudowire. These switching entities ar e re ferr ed t o as unassoc iat ed br idges.
In addition, a switching entity that belongs to a network VLAN is considered an unassociated bridge if
it meets both of the following criteria:
• The network VLAN contains a null Ethernet flow domain (EFD).
• The switching entity contains no switch ports.
Unassociated bridge switching entities can hold Ethernet flow points that serve as termination points on
different network VLANs. If these switching entities are added to a map with the relevant VLANs, the
links are displayed in the Prime Network Vision map.

Adding Unassociated Bridges

Prime Network Vision enables you to add unassociated bridges to maps and to view their properties.
To add an unassociated bridge to a map:
Step 1 In Prime Network Vision, select the required map or domain.
Step 2 Open the Add Unassociated Bridge dialog box in one of the fol lowing way s:
• Choose File Add to Map > Unassociated Bridge.
• In the toolbar, click Add to Map and choose Unassociated Bridge.
Figure 12-39 shows an example of the Add Unassociated Bridge dialog box.
