Displaying VLAN Misconfigurations with Topology Maps
Figure 47: Displaying a misconfigured VLAN
You can solve the misconfiguration problem by selecting the link and using the Add Link to VLAN
command to add the VLAN on the devices at both ends of the link. Or, if the VLAN should not be
configured on either end of the link, you could use the VLAN Manager's Modify VLAN or Modify
VLAN Membership commands to remove port 19 on Bld1Core from the bld1-vlan VLAN.
The ability to quickly recognize misconfigured VLAN links on a Topology map greatly simplifies the
process of tracking down network communication problems among VLANs, as compared to having to
inspect VLAN configuration information on a device by device basis to identify where the
misconfiguration lies.
