How to configure Telnet management for Ruijie Switches in CLI?

1.        Application Scenario & Requirement:
After enabling Telnet on the switch, a host can remotely access the CLI of the switch for device management.
2.        Network Topology:

3.        Configuration Key Points:
a.        The switch requires a management IP address. If the PC and the switch are not in the same network segment, you need to configure a default gateway for the switch.
b.        You need to configure an 'enable' password and a telnet password.
4.        Configuration Steps:
a.        Access switch CLI using a console connection and configure the management IP address:
Ruijie>enable                            ------> enter privileged mode (no 'enable' password by default)
Ruijie#configure terminal            ------> enter global configuration mode
Ruijie(config)#interface vlan 1     ------> enter interface configuration mode of VLAN 1
Ruijie(config-if)#ip address 192.168.1.1 255.255.255.0     ------> set the management IP address for VLAN 1
Ruijie(config-if)#exit
b.        Enable Telnet on the switch:
Option 1. Using password only when accessing switch CLI through Telnet:
Ruijie#config ter

Ruijie(config)#enable service telnet-server

Ruijie(config)#line vty 0 4            ------> enter vty configuration mode, 0 4 means that a total of 5 users are allowed to log in to the switch through telnet at the same time
Ruijie(config-line)#login               ------> enable password protection of the line
Ruijie(config-line)#password ruijie ------> set Telnet password as 'ruijie'
Ruijie(config-line)#exit
Ruijie(config)#enable password ruijie     ------> set the password to enter privilege mode as 'ruijie'
Ruijie(config)#end
Ruijie#write
Option 2. Using username and password when accessing switch CLI through Telnet
Ruijie(config)#line vty 0 4
Ruijie(config-line)#login local        ------> Use local password and password for Telnet connection
Ruijie(config-line)#exit
Ruijie(config)#username admin password ruijie     ------> configure the remote management username as 'admin' and password as 'ruijie'
Ruijie(config)#enable password ruijie
Ruijie(config)#end
Ruijie#write
5.        Verification:
a.        Enter 'telnet 192.168.1.1' on Windows Command Prompt:

b.        A password (or a combination of username and password if Option 2 from above is configured) is required before accessing the switch CLI:

c.        Password is also required to enter privileged mode:

d.        Type 'show users' to view the users currently accessing the CLI:

In the example above, there is 1 console connection and 1 Telnet connection accessing the switch CLI from IP address 192.168.1.2
