# rte\_eth\_vmdq\_dcb\_conf(3)

## NAME

rte\_eth\_vmdq\_dcb\_conf

## SYNOPSIS

`#include <rte_ethdev.h>`

### Data Fields

enum **rte\_eth\_nb\_pools** **nb\_queue\_pools**\
 uint8\_t **enable\_default\_pool**\
 uint8\_t **default\_pool**\
 uint8\_t **nb\_pool\_maps**\
 struct {\
    uint16\_t **vlan\_id**\
    uint64\_t **pools**\
 } **pool\_map** \[**RTE\_ETH\_VMDQ\_MAX\_VLAN\_FILTERS**\]\
 uint8\_t **dcb\_tc** \[**RTE\_ETH\_DCB\_NUM\_USER\_PRIORITIES**\]\

## Detailed Description

A structure used to configure the VMDq+DCB feature of an Ethernet port.

Using this feature, packets are routed to a pool of queues, based on the VLAN ID in the VLAN tag, and then to a specific queue within that pool, using the user priority VLAN tag field.

A default pool may be used, if desired, to route all traffic which does not match the VLAN filter rules.
