Series 3: How do I configure QoS policies to shape WAN traffic bandwidth?

SUMMARY:

This document is intended to guide the CradlePoint administrator through configuring WiPipe QoS Policies to shape LAN and/or WLAN traffic  when accessing  the Internet(WAN).  This is helpful to limit the real-time available bandwidth and limit overall usage on cellular networks where data usage can be expensive.  Although this method can be used to apply to guest networks, this document is intended  for network segments other than guest network access.  For guest access, there is a less granular and simplified method via the hotspot services configuration.

TERMS:

  • QoS:  Quality of Service
  • LAN:  Local Area Network
  • WLAN:  Wireless Local Area Network
  • WAN:  Wide Area Network
  • Mb/s:  Megabits Per Second
  • Kb/s:  Kilobytes Per Second


REQUIREMENTS:

Advanced QoS capable CradlePoint Series 3 products: MBR1400, IBR600, IBR650, CBR400, CBR450


FIRMWARE VERSION:

This content was created using firmware version 5.0.0


ASSUMPTIONS:

The CradlePoint administrator has already setup a working LAN, WLAN and WAN.  All LAN and WLAN devices are able to access the Internet via the CradlePoint’s WAN connection.



EXAMPLE NETWORK TOPOLOGY:

User-added image
In the above topology example there is a representation of  two local hosts.  One host is connected to the wired LAN, and the other host is connected to the wireless WLAN.  On the CradlePoint router, there is a QoS policy defined that is shaping the egress (outbound) and ingress (inbound) traffic to a limit of 20% of the defined WAN bandwidth in each direction.  The Wired WAN connection has 10 Mb/s of defined WAN bandwidth, and the LTE WAN connection has 5Mb/s of defined bandwidth.



CONFIGURATION:

  1. Log Into the CradlePoint Web Administration http://192.168.0.1 (default), if you are unsure how click here.
  2. Under the Network Settings heading, select WiPipe QoS.                                        User-added image
  3. Enable WiPipe QoS and set the WAN Interface bandwidths to the desired rates.
    • Check the box to enable WiPipe QoS
    • Set the Ethernet WAN interface to 10240 Kb/s (= 10 Mb/s)
    • Set the LTE Modem to 5120Kb/s (= 5Mb/s).
    • Click Apply.                                                                                                User-added image
  4. Create a new Queue:
    • Click the Add button under the Queue section.
    • Give the Queue a unique name.
    • Uncheck the Borrow Spare Bandwidth option (if you do not uncheck this option, the traffic will be allowed to use 100% of the bandwidth on each WAN link if bandwidth is available.)
    • Set the Upload Bandwidth to 20%.  Leave all the other settings at the default values.  The Upload priority would only be applicable if you have multiple queues that you want to prioritize traffic between.
    • Click Next.                                                                                                 User-added image
  5. Configure the Download bandwidth:
    • Uncheck the Borrow Spare Bandwidth option (if you do not uncheck this option, the traffic will be allowed to use 100% of the bandwidth on each WAN link if available.)
    • Set the Download Bandwidth to 20%.  Leave all the other settings at the default values.  The Download priority would only be applicable if you have multiple queues that you want to prioritize traffic between.
    • Click Finish.                                                                                                User-added image
  6. Create a new QoS Rule:
    • Add a new QoS Rule by clicking the Add button under the Rules section
    • Name the Rule All Traffic
    • Set the Protocol to Any
    • Set the Queue Name to WAN Shaping
    • Leave all other fields at their default settings.
    • Click Next.                                                                                               User-added image
  7. Leave the Network, DSCP and Port fields blank (default).  This will mark all source and destination traffic.
  8. Click Finish.                                                                                                                      User-added image


The QoS policy will now shape (limit) all ingress and egress WAN traffic to 20% of the defined WAN connections bandwidth limit.
