I am trying to configure a port so that all traffic must be 802.1Q tagged and any untagged traffic is dropped (to replicate the setup of my ancient switch that this one is replacing).
Under VLAN Management | Port Settings, if I select Mode = General and Acceptable Frame Type = Tagged, I still have to enter a PVID!
According to the on-line Help:
PVID: Assigns a VLAN ID to untagged packets. The possible values are 2 to 4094. VLAN 4095 is defined as per standard and industry practice as the discard VLAN. Packets classified to the Discard VLAN are dropped.
However, the input only allows a PVID of 1 - 4094.
Under VLAN Management | VLAN to Ports, selecting 'Join VLAN' against the port in question, pops up a window but it is impossible to remove the untagged VLAN!
How is it possible to configure the port to only allow tagged traffic and drop any untagged traffic?
Many thanks in advance,
