Managing VLANs
The Topology applet, on the other hand, lets you view your VLANs from the perspective of the network
interconnections. By selecting a VLAN you can quickly see the device connectivity enabled by the
VLAN. Through Topology Views you can:
• Identify misconfigured VLAN links
• Select links to add to an existing VLAN or create a new VLANs using the selected link
• Add edge ports to a VLAN that exists on a selected device
Network-wide VLAN Membership Visibility
The VLAN Manager provides a comprehensive view of all the VLANs on your network. The VLAN
Manager’s main view shows you a summary of all VLANs on your network, either by switch or by
VLAN.
Figure 38: Viewing VLANs by switch or by device in the VLAN Manager
By selecting an individual VLAN you can see all the devices and ports that are included in the VLAN.
By selecting an individual device, you see all the VLANs on the device, along with information about
the tag, IP address, protocol, and the ports that belong to each VLAN. You can also view similar
information about the VLANs on a device from the VLAN tab of the Device Properties display for the
device.
A Topology View with VLAN information displayed shows you, for a given VLAN, the devices on the
map that have the VLAN configured, and the links that connect the VLANs on those devices. Figure 39
shows an example of the display for a selected VLAN.
