24.3 MES-2110 Configuration and Console

I’m trying to configure MVR but I get an error message.

MVR only functions with Tag-Based (802.1q) VLANs. To rectify this:
Open the Configuration > VLAN Menu > VLAN Type screen and set the
VLAN Type option to Tag-Based (802.1q).
Or
Connect to the MES-2110 through the console port (Chapter 23 on page 179)
and enter the following commands:.

I applied changes in the Web Configurator but they are not taking effect.

Makes sure that you saved all configuration changes using the Save Settings
link in the Web Configurator’s navigation pane.
Clean out the cache of the browser that you are using to connect to the MES-
2110’s Web Configurator, and make sure that you’re only using a browser
supported by the device (Chapter 1 on page 19)
Try making your changes through the MES-2110’s command line interface
(Chapter 23 on page 179), and using the write memory command to make the
changes permanent.
Power off the MES-2110, then power it back on and make your changes afresh.
Reset the MES-2110 to its factory default settings (Section 5.6 on page 59).
If the problem continues, contact the vendor.
