Configuring Modem Connections
Modems can only be configured if you are connected to the console or COM1 ports. A modem
connection to a switch in the Cisco MDS 9000 Family does not affect switch functionality.
If you plan on connecting a modem to the console port or the COM1 port of a switch in the Cisco MDS
