The Device_Viewer>Interface>Configuration page shows the interfaces and their configurations. If there is an IP address configured, it will appear with the interface. If HSRP or secondary addressing is configured, the interface will have more than one address. How should this be displayed?
In the Interface>Address page, there's a separate row for each address, so the data exists elsewhere. One answer is to have multiple rows in the Configuration display, one for each address. Another is to list the addresses on the interface. There may be other answers.
