1-2User interface Applicable user Port used DescriptionVTY Telnet users and SSH users Ethernet portEach switch canaccommodate up to fiveVTY users.Users and User InterfacesA device can support two AUX ports and multiple Ethernet interfaces, and thus multiple user interfacesare supported. These user interfaces do not associate with specific users.z When the user initiates a connection request, based on the login type the system automaticallyassigns a type of idle user interface with the smallest number to the user.z During the login, the configuration in the user interface view takes effect. The user interface variesdepending 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 userthat has logged in. For example, if user A uses the console port to log in, the configuration in userinterface view of the console port applies to user A; if user A logs in through VTY 1, the configuration inuser interface view of VTY 1 applies.User Interface NumberUser interfaces can be numbered in two ways: absolute numbering and relative numbering.Absolute numberingAbsolute numbering allows you to uniquely specify a user interface or a group of user interfaces. Thenumbering system starts from number 0 with a step of 1. The numbering approach numbers the twotypes of user interfaces in the sequence of AUX port and VTY.Relative numberingRelative numbering can specify a user interface or a group of user interfaces of a specific type. Thenumber is valid only when used under that type of user interface. It makes no sense when used underother types of user interfaces.Relative numbering numbers a user interface in the form of “user interface type + number”. The rules ofrelative numbering are as follows:z AUX user interface number is 0 and 1.z VTYs are numbered from 0 in ascending order, with a step of 1.Common User Interface ConfigurationFollow these steps to perform common user interface configuration:To do… Use the command… RemarksLock the current user interface lockOptionalExecute this command in userview.A user interface is not locked bydefault.
