Telnetting to a Switch

Telnetting to a Switch from a Terminal

1) Assign an IP address to VLAN-interface 1 of the switch (VLAN 1 is the default VLAN of the switch).
Connect the serial port of your PC/terminal to the console port of the switch, as shown in
Figure 3-4 Diagram for establishing connection to a console port
Launch a terminal emulation utility (such as Terminal in Windows 3.X or HyperTerminal in
Windows 95/Windows 98/Windows NT/Windows 2000/Windows XP) on the PC terminal, with the
baud rate set to 19,200 bps, data bits set to 8, parity check set to none, and flow control set to none.
Turn on the switch and press Enter as prompted. The prompt appears.
Perform the following operations in the terminal window to assign IP address 202.38.160.92/24 to
VLAN-interface 1 of the switch.
<Sysname> system-view
[Sysname] interface Vlan-interface 1
[Sysname-Vlan-interface1] ip address 202.38.160.92 255.255.255.0
