3G/4G Uplink Support on Enterprise (e600) AP

Brief : cnPilot AP 3G/4G Uplink Enterprise

  • Network needs failover connection to reduce the downtime costs.
  • Enterprise traditionally use Analog lines and ISDN connections for failover.
  • With emergence of LTE, 3G/4G have surpassed older technologies.
  • Cambium Networks e600 AP comes with LTE support to provide primary internet and the backhaul.

Typical network Setup               

Supported model and How feature works 

  • The support for cellular uplink is added in cnPilot version - 3.11-r1 (CLI support is already added in 3.10 version )
  • As of now, we support two models of dongles:
    • Huawei E8372
    • Huawei E3372
  • 3G/4G Uplink can be configured two modes, Failover only checked and unchecked.
    • If Failover only is unchecked, then 3G/4G (WWAN ) will be the only working connection.
    • If Failover only is checked, then Ethernet will be the primary connection and WWAN will be backup.
  • This is how 3G/4G failover works :
    • Running a check in the background that constantly monitors a user configured IP address (Eg: 8.8.8.8) for reachability through ping.
    • If the IP is reachable and 3G/4G interface is down, do nothing (since we have wired connectivity, which is preferred).
    • If the IP is not reachable and LTE interface is down, then bring up the LTE interface. If it is already up let it remain up.
    • If the IP is reachable and LTE interface is UP, periodically Ethernet connections is checked
    • If LTE signal is lost before the periodic interval, a keep-alive method is triggered in the background to switch to wired

               Note : Cellular link can be configured as backup only to Ethernet connection

Management

  • WEBUI Configuration
    • Click the Configure link on the cnPilot main window.
    • In the Configure window, click the Network settings
    • Click the WWAN tab and configure the following parameter as shown in figure

  • CLI Configuration

Show/Debug commands

  •  service show debug-logs infrad, will show you the WWAN bring up status
  • show ip interface brief
  • show events

Hello,

This is very useful! 

Are there improvements since then?

Are another dongles supported now?

Thank you,

Bálint

the two Huawei dongles are what we support today. If you would like to use some other dongle could you please most the make and model, and we can explore adding support.

thanks.

Hello,

We are using the Huawei E3276 model. 

Thank you!

One more thing,

Is it possible to add more than one monitor host? To avoid the case if the monitor host 1 being unavailable..

hi,

no option to add 2nd ip to the monitoring list. what is the use we are trying to solve having 2 ip addresses for monitoring?

For example the host what we are checking is down, but our connection is ok. Would be useful a 2nd one in my opinion.
