Users And User Interfaces; User Interface Number; Common User Interface Configuration - 3Com 4510G Configuration Manual

Users and User Interfaces

A device can support one Console ports and multiple Ethernet interfaces, and thus multiple user
interfaces are supported. These user interfaces do not associate with specific users.
When the user initiates a connection request, based on the login type the system automatically
assigns a type of idle user interface with the smallest number to the user.
During the login, the configuration in the user interface view takes effect. The user interface varies
depending on the login type and the login time.
At a time, only one user can use the user interface. The user interface configuration applies to the user
that has logged in. For example, if user A uses the console port to log in, the configuration in user
interface view of the console port applies to user A; if user A logs in through VTY 1, the configuration in
user interface view of VTY 1 applies.

User Interface Number

User interfaces can be numbered in two ways: absolute numbering and relative numbering.
Absolute numbering
Absolute numbering allows you to uniquely specify a user interface or a group of user interfaces. The
numbering system starts from number 0 with a step of 1. The numbering approach numbers the two
types of user interfaces in the sequence of AUX port and VTY.
Relative numbering
Relative numbering can specify a user interface or a group of user interfaces of a specific type. The
number is valid only when used under that type of user interface. It makes no sense when used under
other types of user interfaces.
Relative numbering numbers a user interface in the form of "user interface type + number". The rules
of relative numbering are as follows:
AUX user interface number is 0.
VTYs are numbered from 0 in ascending order, with a step of 1.

Common User Interface Configuration

Follow these steps to perform common user interface configuration:
To do...
Lock the current user interface
Specify to send messages to
all user interfaces/a specified
user interface
Disconnect a specified user
interface
Use the command...
lock
send { all | number | type
number }
free user-interface [ type ]
number
1-2
