3 Multiple Channels Policing
In case if the operator has several external (uplink) or internal channels often it is needed to control Channel Upper Boundary and limit low priority traffic independently of one another. Channel traffic is usually uneven and channels often are unequal.
Setting the channel parameters and constraints in the channel is same as subscribers rate plans using special identifier.
In the DPI setting /etc/dpi/fastdpi.conf there is a parameter to select distinguish type for channels:
vchannels_type=1
where
- 1 using NICs for different channels
- 2 using VLANs for different channels
After it you have to set NICs or VLANs list for virtual channels.
For NICs:
vchannels_list=dna0:dna1|dna2:dna3
NICs that is not in vchannels_list but in in_dev/out_dev will be in general channel as before. It is managed as usual in configuration file
For VLANs:
vchannels_list=100:101-115|200:201:240-250
Policing Configuration
Load the policing setting for channels 1 and 2
fdpi_ctrl load --policing vchannel1.cfg --vchannel 1 fdpi_ctrl load --policing vchannel2.cfg --vchannel 2
where vchannel1.cfg - file with policing definition (same as for the general channel,virtual channels and subscriber rate plans)
Example of configuration file:
htb_inbound_root=rate 10mbit htb_inbound_class0=rate 8bit ceil 10mbit htb_inbound_class1=rate 1mbit ceil 3mbit htb_inbound_class2=rate 8bit ceil 10mbit htb_inbound_class3=rate 8bit ceil 10mbit htb_inbound_class4=rate 8bit ceil 10mbit htb_inbound_class5=rate 8bit ceil 10mbit htb_inbound_class6=rate 100mbit static htb_inbound_class7=rate 8bit ceil 10mbit htb_root=rate 10mbit htb_class0=rate 8bit ceil 10mbit htb_class1=rate 1mbit ceil 3mbit htb_class2=rate 8bit ceil 10mbit htb_class3=rate 8bit ceil 10mbit htb_class4=rate 8bit ceil 10mbit htb_class5=rate 8bit ceil 10mbit htb_class6=rate 100mbit static htb_class7=rate 8bit ceil 10mbit
Let's check what settings is loaded:
fdpi_ctrl list all vchannel --policing
The settings for the virtual channels are stored in DPI UDR (internal database) and can be changed on the fly during operation as well as for subscribers. Configuration of policing for the channel can be loaded by the named profile eather.
fdpi_ctrl load --policing --profile.name vchannel_1 --vchannel 1
The tariff plan can be set in JSON format as well.
Block List Setup - Service 4
The profile is created similarly to creating Subscriber's profile: Filtering Management.
fdpi_ctrl load --service 4 --profile.name test_blocked ––vchannel 2
Allow List Setup - Service 5
The profile is created similarly to creating Subscriber's profile: Allow List Management.
fdpi_ctrl load --service 5 --profile.name test_white ––vchannel 1
