 ### Adding new vlan interface
 
+You need to add following line in /etc/accel-ppp.conf
 ```
-interface=bond0.2529,{"services":["zone1","Flexnet","ferrari2","fi","rp","pr","dotnet"],"service-blank":1}
+interface=bond0.2529,{"services":["zone1","Flexnet","IDM","fi","rp","pr","dotnet"],"service-blank":1}
 ```
 Possible options:
-* services - list of PPPoE services to be added to the interface
+* services - list of PPPoE services to be added to the interface, if you dont want any omit this parameter
 * service-blank - if set to 1, then user that didnt specify service can connect to this pppoe
-* service-any - if set to 1, then user that specified any service can connect to this pppoe
+* service-any - if set to 1, then user that specified any service can connect to this pppoe, if not needed - omit this parameter
 
 After updating accel-ppp config, you need to run script that will create vlans and add vlans to accel without restart:
 ```
 sh /etc/add_accel_vlans.sh
 ```
 
+You can verify vlan is created by using following command:
+```
+ip link show bond0.2529
+```
+Make sure it is activated in accel-ppp:
+```
+accel-cmd pppoe interface show
+```
+Also you can check mac addresses on /proc/net/pppoe, and exclude only those you want for specific vlan using grep:
+```
+grep bond0.2529 /proc/net/pppoe
+```
