Topology Vie w

Topology Icons

The Topology vi ew and the cluster tre e use the sam e set of device icons to represent clusters, command
and standby c omm and sw it ches, a nd m embe r swit che s (see Figure 3-10). The Topology vi ew also use s
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
Cisco Discovery Protocol (CDP )-capab le hubs and rout ers
Note The System Switch Processor (SSP) card in the Cisco Integrated Communications System
(ICS) 7750 appears as a Layer 2 switch. SSP cards are not eligible to join switch clusters.
•Devices that are identified as unknown devices, such as some Cisco device s and third-party devices
Tip Neighbor ing devices are onl y displaye d if they are conne cted to cluster me mber s. To display
neighboring devices in the Topology view , either add the switch to which they are connected to a cluster,
or enable that switch as a command switch.
