Configuring the basic access function
An S9800 switch without any configuration can perform basic data forwarding immediately after it is
plugged into a network. To implement more forwarding features, configure the basic network settings
in Table 6 on the switch.
Table 6 Basic network settings
Setting Description
IP address Enables remote switch management, for example, by using Telnet.
Static routes Implement static routing.
VLANs Divide the LAN into multiple VLANs for data security.
Configuration example
Configuring Telnet service
# Enter system view.
<Sysname> system-view
# Enable the Telnet server.
[Sysname] telnet server enable
# Enter the view of user line VTY 0.
[Sysname] user-interface vty 0
# Enable password authentication on the user line.
[Sysname-ui-vty0] authentication-mode password
# Set the password to hello in plaintext.
[Sysname-ui-vty0] set authentication password simple hello
# Assign user role network-admin through the user line VTY 0.
[Sysname-ui-vty0] user-role network-admin
[Sysname-ui-vty0] quit
Configuring the basic network settings
• Configure IP addresses
# Create VLAN-interface 1.
[Sysname] interface vlan-interface 1
# Assign an IP address, for example, 192.168.0.1, to VLAN-interface 1.
[Sysname-Vlan-interface1] ip address 192.168.0.1 24
