Console and Aux Port Cables
Different Catalyst Supervisor Engines use either a rolled or a straight-through cable in order to connect a
terminal or modem to the console port. Refer to these documents for information on how to connect a
terminal or modem to the console port of Catalyst series switches:
● Connecting a Terminal to the Console Port on Catalyst Switches
● Connecting a Modem to the Console Port on Catalyst Switches
Auxiliary (AUX) ports on Layer 3 (L3) switches or modules behave much the same way as AUX ports on
routers and are used to connect modems. Refer to Modem-Router Connection Guide for information on
how to connect a modem to an AUX port.
