2.6802.1Q VLAN

IEEE 802.1q (tag-based) VLAN’s can add or strip 802.1q tags based on your parameters set for each transmitting port. Select the 802.1Q VLAN menu to activate the following page where this function can be configured.

Currently the switch supports up to 32 tag-based VLAN groups for manual entry. The following pages will described in detail how to configure this feature.

Warning !!!

Incorrect configuration of Tagged VLAN can create a situation where the web interface of the switch cannot be accessed. This can occur when the PVID of the port you are using or the VID of the VLAN group the port belongs to is not on the same as the CPU PVID, and the port is configured to drop untagged ingress frames.

The CPU port (this is not a physical port) is a member of PVID 1 by default.

To adjust the CPU port PVID settings, select the port via port number 25. (Console only option) ie. VP then 25 will display PVID = 1

In the case that you do configure this state and lock the web interface out, then you can recover by connecting to the RS-232 console port and either disabling Tagged VLAN, or adjust the settings via the following options.

VE - Enable/Disable 802.1Q VLAN

VF – Get 802.1Q VLAN Enable Setting

VV– Set PVID VP – Get PVID
