Choosing the last option (8) of the advanced device control menu will cause the device to return to its default settings and restart. This may require a few seconds to complete. The default values are given in the status section. It is recommended to reset the device after this operation.

Management control menu

The management control menu (figure 6-15) provides the same options as other advanced port priority menus. These settings apply to in-bound and out-bound management traffic going through the ‘virtual management port’. Consider them as if they apply the same way as they do with any other port.

Management control:

===================

1.Enable/Disable tag insertion

2.Enable/Disable tag stripping

3.Set VLAN ID

4.Enable/Disable priority

5.Enable/Disable 802.1p priority

6.Enable/Disable TOS priority

7.Set user priority

0.Back to port control menu Select (0-7):

Note that changing some settings (such as the VLAN ID) may cause management traffic to be stopped, thus disconnecting the management station from the device.

Please note that the VLAN related features (namely, tagging options) would take effect when the VLAN mode is ‘enabled’.
