Topology View
Topology Icons
The Topology view and the cluster tree use the same set of device icons to represent clusters, command
and standby command switches, and member switches (Figure 3-8). The Topology view also uses
additional icons to represent these types of neighboring devices:
•Customer premises equipment (CPE) devices that are connected to Long-Reach Ethernet (LRE)
switches
•Devices that are not eligible to join the cluster, such as Cisco IP phones, Cisco access points, and
CDP-capable hubs and routers
•Devices that are identified as unknown devices, such as some Cisco devices and third-party devices
Note Candidate switches are distinguished by the color of their device label. Device labels and their colors
are described in the “Colors in the Topology View” section on page 3-14.
To select a device, click the icon. The icon is then highlighte d. To select multiple devices, you can either:
•Press the left mouse button, drag the pointer over the group of icons that you want to select, and then
release the mouse button.
•Press the Ctrl key, and click the icons that you want to select.

two devices. To select a link, click the link that you want to select. To select multiple links, press the
Ctrl key, and click the links that you want to select.
