======Handling traffic by VLAN======

  - Drop traffic without analysis from a specific VLAN:<code bash>fdpi_cli vlan group <id> drop</code>
  - Dropping traffic with preliminary analysis, but without transferring it to Netflow statistics from a specific VLAN (Used to deal with asymmetric traffic when a site receives a double of traffic from another site. It is necessary to analyze and drop the traffic so that it is not included in the statistics):<code bash>fdpi_cli vlan group <id> hide</code>
  - Passing traffic without any analysis from a specific VLAN:<code bash>fdpi_cli vlan group <id> pass</code>
  - Display existing settings in the UDR: <code bash>fdpi_cli vlan group 0 show all</code>Example output of the command:<code bash>fdpi_cli vlan group 0 show all
<proto> <vlan> <service-name> <policy> <delay>
all 4000 *  hide 0
all 4002 *  hide 0
all 4003 *  hide 0</code>In this example, you can see that all protocols belonging to VLAN 4000, 4002, 4003 are affected by hide, that is, traffic from one site is duplicated to another site.
  - Output all properties for a group with a specific id:<code bash>fdpi_cli vlan group <id> show all</code>Here ''id'' is the number of the VLAN for which you want to output Service-Name information.
