VLAN tags not visible at the analyzer
All TAPs pass VLAN tags with the packets. If you are not seeing the VLAN tags at the analyzer, check the following:
♦On the switch:
●Confirm that the SPAN was created to pass VLAN tags. Sometimes SPANs are created and passing VLAN tags is not enabled.
●Confirm the communication between the switch and the router is passing the VLAN tags (normally the communication between them is not a trunk).
♦On a GigaStor, if you are using one:
●Confirm the capture card has been enabled to receive or pass VLAN tags.
