Our POE series of managed switches have a management interface. The default VLAN for this managed interface is vlan1. If the VLAN ports on the switch are changed to another VLAN, the devices on the switch will no longer be able to reach the management IP of the switch.
There are two ways to change the management VLAN of the switch:
Option 1:
Change the management VLAN in the webgui:
Default IP address for the switch is 192.168.254.1
Once logged in:
- Click on "Layer2 Manage"
- Click on "Vlan Config"
- Navigate to the "Manage VLAN Config" tab
- Select the desired management VLAN and click on "Set"
After this configuration the management webgui will only be accessible from ports that have the same VLAN configured.
Option 2:
If you still have access to the switch management VLAN you can use telnet to login to the switch CLI. Otherwise, connect the switch console port to the computer serial port with a combination of an RJ45 to RS232 converter cable and an RS232 to USB converter cable. Use a program like PuTTY to telnet into the switch via the console port.
Once logged into the switch CLI you can issue the following commands:
enable
configure terminal
vlan manage vlan#
With vlan# being the numerical value of the VLAN you would like to set. Example: vlan manage 80
