Configuring Terminal Settings and Sessions

Virtual Terminals

You can use virtual terminal lines to connect to your Cisco NX-OS device. Secure Shell (SSH) and Telnet
create virtual terminal sessions. You can configure an inactive session timeout and a maximum sessions limit
for virtual terminals.

Modem Support

You can connect a modem to the COM1 or console ports only on the supervisor 1 module. The following
modems were tested on devices running the Cisco NX-OS software:
• MultiTech MT2834BA (http://www.multitech.com/en_us/support/families/multimodemii/)
• Hayes Accura V.92 (http://www.zoom.com/products/dial_up_external_serial.html#hayes)
Note Do not connect a modem when the device is booting. Only connect the modem when the device is powered
up.
The Cisco NX-OS software has the default initialization string (ATE0Q1&D2&C1S0=1\015) to detect
connected modems. The default string is defined as follows:
AT
E0 (required)
