If media information is available for a port, then you can select the name of the transmission medium used (the media type) from the CATEGORY popup menu:

Token Ring

For TTY port types (console ports and auxiliary ports), CiscoView displays terminal services configuration information. Asynchronous ports must be configured before they can be managed with CiscoView.
