Experimental topology：
Set switch management IP address and Telnet login
analyze:
On the switch, if the switch has a management interface, configure an IP address for the management interface. If the switch has no management interface, configure an IP address for the VLANIF interface. The configured management IP address allows the network administrator to remotely manage the switch using Telnet or network management software.
You can log in to a switch 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.
1. For example, you can perform the following configurations on the switch:
<HUAWEI> system-view
[HUAWEI] interface meth 0/0/1
[HUAWEI-MEth0/0/1] ip address 192.168.0.253 24
[HUAWEI-MEth0/0/1] quit
If the switch has no management interface, configure an IP address for the VLANIF 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 192.168.0.253 24
[HUAWEI-Vlanif4094] quit
Configure reachable routes between the PC and switch so that the PC can successfully ping the switch.
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.
If the PC is not directly connected to the switch, configure reachable routes between the PC and switch.
2. 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
3. Configure the Telnet login user parameters. Set the user name and password to admin@6789, and user level to 3.
[HUAWEI] aaa
[HUAWEI-aaa] local-user admin password irreversible-cipher admin@6789
[HUAWEI-aaa] local-user admin privilege level 3
[HUAWEI-aaa] local-user admin service-type telnet
The workstation pc-01 in the network segment where the switch resides can remotely manage the switch in Telnet mode.
telnet 192.168.0.253
This is what I want to talk about/share with you today, thank you!
