Ports

8.8.5 Restricting Commands

The Security characteristic may be used to limit a user's access to information about other ports. When
Security is enabled, only a limited number of commands may be typed at the Local> prompt. A user on a
secure port are unable to get information about other ports using the Show/List commands and can not
perform commands which require privileged access.
To enable Security on a particular port, use the Set/Define Ports Security command.
Local>> DEFINE PORT 3 SECURITY ENABLED

8.8.6 Receipt of Broadcast Messages

The Set/Define Ports Broadcast command enables or disables a port's receipt of broadcast messages from
other users, including the superuser. Broadcast messages are enabled by default.
Local>> DEFINE PORT 3 BROADCAST DISABLED
Broadcast messages are also discussed in Sending a Broadcast Message on page 2-5.

8.8.7 Dialback

The Dialback feature allows a system manager to set up a dialback list of authorized users for incoming
modem connections. When a username matching one in the list is entered, the port is logged out and the
phone number will be sent out the serial port using the port's modem profile.
For a complete description of dialback, see Security on page 11-1.

8.8.8 Enabling Menu Mode

If you want to limit user access to the Local> prompt, you can set up a menu with restricted options. The
Set/Define Ports Menu enables menu mode for the specified ports.
Local>> DEFINE PORT 3 MENU ENABLED
When Menu mode is enabled, the Local> prompt cannot be accessed. Be sure that you have another way to
log into the SCS before enabling Menu mode on all ports.
