How Do I Configure the Telnet Login Function

How Do I Configure the Telnet Login Function?

You can log in to a switch (I use the S2700-26TP-EI-AC most time) through Telnet only when the switch has an IP address and the VTY

user authentication method and VTY user level have been configured. By default, the preceding

configurations are unavailable on the switch, and you must log in to the switch through the

console interface and complete the configurations.

Perform the following configurations:

1. Set a management IP address for the switch.

A # If the switch has an management interface, configure an IP address for the management

interface.

<HUAWEI> system-view

[HUAWEI] interface meth 0/0/1

[HUAWEI-MEth0/0/1] ip address ip address 192.168.1.2 24

[HUAWEI-MEth0/0/1] quit

B # If the switch has no management interface, configure an IP address for the WLANIF

interface.

<HUAWEI> system-view

[HUAWEI] vlan 4094

[HUAWEI-vlan4094] quit

[HUAWEI] interface gigabitethernet 0/0/48

[HUAWEI-GigabitEthernet0/0/48] port link-type hybrid

[HUAWEI-GigabitEthernet0/0/48] port hybrid untagged vlan 4094

[HUAWEI-GigabitEthernet0/0/48] quit

[HUAWEI] interface vlanif 4094

[HUAWEI-Vlanif4094] ip address ip address 192.168.1.2 24

[HUAWEI-Vlanif4094] quit

2. Configure reachable routes between the PC and switch so that the PC can successfully ping

the switch.

A If the PC is directly connected to the switch, ensure that the IP address of the PC is in

the same network segment as the management IP address of the switch.

B If the PC is not directly connected to the switch, configure reachable routes between

the PC and switch.

3. Set the authentication mode for Telnet login to AAA.

[HUAWEI] user-interface vty 0 4

[HUAWEI-ui-vty0-4] authentication-mode aaa

[HUAWEI-ui-vty0-4] quit

4. Configure the Telnet login user parameters. Set the user name and password to admin, and

user level to 3.

[HUAWEI] aaa

[HUAWEI-aaa] local-user admin password cipher admin

[HUAWEI-aaa] local-user admin privilege level 3

[HUAWEI-aaa] local-user admin service-type telnet

Note:

This configuration works for Huawei S2700, Huawei S3700, Huawei S5700 and Huawei S6700.
