Topology View Popup Menus

These popup menus are available in the Topology view.

Link Popup Menu

You can display reports and graphs for a specific link displayed in the Topology view (Table 3 -15). To

display the link popup menu, click the link icon, and right-c lick.

The Link Report and Link Graph options are not available if at b oth en ds o f the l ink ar e

•Candidate switches

•Catalyst 1900 and Catalyst 28 20 switche s

•Devices that are not eligible to join the cluster

If multiple links are configured between two devices, when you cli ck t he l ink ic on an d ri ght- cli ck, the

Multilink Content window appears (Figure3-10). Click the link icon in this window, and right-click to

display the link popup menu specific for that link.

Link Report Display the link report for two connected devices. If one device is an unknown

device or a candidate, only the cluster member side of the link displays.

Link Graph Display a graph showing the current bandwidth used by the selected link. You

can change the graph polling interval by selecting CMS > Preferences.

Properties Display information about the device and port on either end of the l ink and the

state of the link.
