====== Setting the termination parameters for each output DPDK interface ======
{{indexmenu_n>2}}
<note warning>Warning: this feature should be used after careful consideration. Often, instead of specifying special options for output interfaces, you need to revisit the network topology.</note>

In the VAS Experts DPI 7.4+ a new feature to specify termination parameters for each output DPDK interface on your own is added.
The ''bras_term_dev_outer'' option is used for this purpose:
<code>
   # The option sets the termination modes for the particular output interface
bras_term_dev_outer=dev=41-00.1;bras_gateway_ip=188.227.73.41;bras_gateway_mac=00:e0:ed:43:84:41;bras_vlan_terminate=1;bras_vlan_subst=1907;bras_terminate_l2=1
</code>
Here ''dev'' specifies the name of the DPDK output interface, the other parameters are used to define this output interface.
The following [[dpi:bras_bng:bras_l2_vlan_term|termination options]] can be specified:
  * bras_gateway_ip
  * bras_gateway_mac
  * bras_vlan_terminate
  * bras_vlan_subst
  * bras_terminate_l2

For each output interface its options can be specified by a new line
<code>
bras_term_dev_outer=dev=41-00.1;bras_gateway_ip=188.227.73.41;bras_gateway_mac=00:e0:ed:43:84:41;bras_vlan_terminate=1;bras_vlan_subst=1907;bras_terminate_l2=1
bras_term_dev_outer=dev=42-00.1;bras_gateway_ip=188.100.10.101;bras_gateway_mac=45:10:10:55:39:e5;bras_vlan_terminate=3;bras_vlan_subst=666;bras_terminate_l2=1
</code>

If the ''bras_term_dev_outer'' option is not specified for the output interface, then the corresponding global settings are used for it.

<note important>All the needed termination options should be specified within the ''bras_term_dev_outer'' option. The VAS Experts DPI does not compound
[[dpi:bras_bng:bras_l2_vlan_term|the global termination options]] and options that are specific for the particular interface.</note>
