Port groups

The SCS supports access control groups which are composed of one or more serial ports. This feature allows a user to
be granted access to a group of ports, using a single specification. Each port can belong to only one group. A port
group may then be specified in a user account. A user account can specify up to 16 port groups.
For example, assume that ports 1, 2, 3, and 4 are assigned to a group named LINUX. Ports 5, 6, 7, and 8 are
assigned to a group named ROUTERS.
Users who must be able to access all Linux devices will have the LINUX group specified in each of their user accounts.
Those users can access the devices connected to ports 1, 2, 3, and 4.
port 1,2,3,4 set group=linux
Users who must be able to access all router devices will have the ROUTERS group specified in each of their user
accounts. Those users can access the devices connected to ports 5, 6, 7, and 8.
port 5,6,7,8 set group=routers
Users who must be able to access Linux and router devices will have both the LINUX and the ROUTERS groups
specified in their user accounts. Those users can access the devices connected to ports 1 through 8.

Configuring TD=console serial port settings

Issue a Port Set command. You can specify settings for one port, multiple ports, or all ports.
port [<port>|all] set td=console [name=<name>] [baud=<baud>] [size=<size>]
[parity=<parity>] [stop=<stop_bits>] [flow=<flow_ctrl>] [timeout=<time-out>]
[socket=<socket>] [char=^<cli_char>] [toggle=none|dtr] [power=<signal>]
[group=<group>]
See "Port set command."
Displaying serial port settings
Issue a Show Port command.
show port [<port>|all|names|groups]
When you request information about a port configured as td=console, the display includes configuration information,
current power status (if power status monitoring has been enabled), plus transmit, receive, and error counts. When
you request information about a single port and a user is currently accessing that port, the display also includes the
user name, access rights, and other information about the current session.
The display for Show Port Names includes the port numbers and names. If a port name has not been changed with a
Port Set command, the logical name displays. The display for Show Port Groups includes the port number and
port group name, if assigned.

Connecting to serial devices

The SCS offers several methods for connecting to attached serial devices: Telnet, serial CLI, PPP, and SSH.
You can use the session sharing feature to permit multiple concurrent connections to a port. See "Session sharing."

Connecting to devices using Telnet

Each SCS serial port is directly addressable through a unique TCP port that provides a connection to the attached
serial device.
Plain text (non-encrypted) Telnet connections are enabled by default. See "Enabling plain text Telnet and SSH
connections" and "Sever security command."
You can access the SCS and its ports using Telnet client or third-party Telnet client applications.
