Zyxel Switch [CLI] - Configure the IP address of switch via console [CLI]

For various reasons such as access problems via the Ethernet interface, it may be necessary to change the IP address of one of your Zyxel switches by connecting directly to the console interface.

However, the commands presented here are also valid for telnet and SSH interfaces.

Connect the serial port to your computer and switch and configure your terminal software with the following settings:

Emulation: VT100
Speed: 9600 bauds
Data: 8 bits
Parity: none
Stop: 1 bit
Flow control: none

Once identified on your device, use the following commands to change the IP address of your switch.

In the example below, the IP address of VLAN 1 will be changed to 172.31.255.71 with a subnet mask in 255.255.255.0.

sysname # configure
sysname (config) # vlan1
sysname # config # ip address default-management 172.31.255.71 255.255.255.0
sysname (config) # exit
sysname # write
sysname # exit
