This displays the current physical topology with color- coding (displayed with a key in the lower right corner) for ISL utilization. You can hover over the switch indication circles to display the configured switch name, IP address, switch model, firmware version, last polled CPU utilization, and last polled memory utilization.
The memory or CPU utilization are displayed on the switch indicators. In addition the ISL/Trunk paths are also color-coded based on their TX+RX peak utilization. You can hover over the ISL/Trunk to show list of ports that create the connection and click on individual paths to launch the performance chart showcasing TX and RX utilization for the last 24 hours.
Click the + symbol in the upper-right corner to maximize the window and enables you to drag the switch icons to best display their infrastructure. Once icons are placed in the most desirable position you can save the layout by clicking the Save icon in the upper-left corner of the topology map. If the layout is moved you can restore the previously saved layout during the current session by clicking the Restore icon in the upper-left corner next to the save icon.
When the number of nodes is large, the switch information will not be displayed, as it cannot be accommodated on the page. However, if you click the Switch Name or use filters down to a subset, you will be able to view the switch information.
VxLAN VTEPs are shown in topology with VTEP icons. Click on the filter in top right corner in topology screen to search VTEPs based on VNI (VNI value > 4095) or multicast address. A Details link appears below the filter box. Click on the Details link below the filter box to view the search data in tabular format. In VNI search context, click VTEP to view the VTEP active peers.
