Two active LTE interfaces(Hot channels) for 899G-LTE

[george.mikoyan891]

Hi dear Engineers

I'm trying to configure Cisco C899G-LTE  router for using two active 3g or LTE channels simultaneously.

I have tried already with EEM scripts to implement failover, it is works somehow, but I can't make two cellular interfaces to be up and operational at the same time.

Please provide me documentation or share with Your practice...

Also see attached cisco.com link where says that it is possible by using "PDN".

Thank You!

Hello,

just happen to search for answer and found this config in reply:

In one of the forum, someone indicated that for Cisco IR829 it uses both Antenna Main/AUX to receive traffic, but use only main to upload traffic. My question is do we need to do any configuration to interface Cellular0/1? does it need to be shutdown? or leave it in its default configuration (no shut) to receive traffic in AUX Antenna (or Diversity Antenna)? I have some intermittent drops in our Mobile Vehicle with IR829 using one of the main LTE carrier in LA on Video Streaming. We only have one Antenna on the roof of the Vehicle. If we purchase another Antenna, would we connect to AUX 0, and not need any configuration to the interface Cellular0/1 for the main cellular LTE Carrier's traffic?

Hello dear Georg, thank you for Your responce. But in my device I have  just one controller and two cell interfaces, Please see bolded part of  configuration .

Hello,

with only one controller, unfortunately, you can only do a failover, you cannot have both connections active at the same time. If you want to configure this and need help, let me know...

[george.mikoyan891]

Thank You very much for information and for help. I have already successfully configured filover feature, I'll contact You if any questions appear

[bahaa.mohamed@hotmail.com]

Could you share with me if we can operate two cellular interfaces at the same time on cisco 898  LTE router . i have two cellular interfaces but only one controller .

[Georg Pauwen]

Hello,

the short answer is: with only one controller, you cannot operate both cellular interfaces at the same time. Failover is the best you can achieve.

I think the IR829 has two controllers...

[bahaa.mohamed@hotmail.com]

Thanks a lot . I have router cisco 898EAG-LTE , and it have two cellular interfaces (cellular 0 & cellular 1) 

Is there any way to configure the two cellular interface to work at the same time however as mentioned above only only controller cellular 0 is configured  on my router and no controller cellular 1 is available  so what is the use for the second cellular interface ?

Also what can we do if  fail-over doesn’t  operate automatically between the two sims at cellular 0

[Georg Pauwen]

Hello,

one controller means only one SIM can be active. How do you have your failover configured ? Best to post the full running config of your 899 router...

[bahaa.mohamed@hotmail.com]

Hello ,

Kindly find the below configuration for my Cisco 898 router

I need your support to know the use of cellular 1 or how can i active it if i have only controller cellular 0 

and for fail-over the router have 2 SIMS , if the first one is down , the second will be active automatically

but sometimes fail-over need to be done manually by activate the second slot  so i need to know the use of cellular 1 

Thanks again
