Cisco 4G LTE Router Configuration How To

In this video I take you though the configuration of a cellular interface on a Cisco router. This process will be similar on most Cisco 4G interface cards however this particular setup was done on an IR829 Industrial router. After configuring I also show some of the troubleshooting commands to review signal strength, verify the carrier, etc on this system.
I suggest this document from Cisco to understand the configuration in more depth: www.cisco.com/...
The applicable configuration:
controller Cellular 1
description AT&T
lte sim data-profile 1 attach-profile 1
no lte gps enable
lte modem link-recovery rssi onset-threshold -110
lte modem link-recovery monitor-timer 20
lte modem link-recovery wait-timer 10
lte modem link-recovery debounce-count 6
interface Cellular1/0
ip address negotiated
encapsulation slip
load-interval 30
dialer in-band
dialer string lte
dialer-group 1
no peer default ip address
routing dynamic
dialer-list 1 protocol ip permit
ip route 0.0.0.0 0.0.0.0 Cellular1/0

What is your most unique use case for 4G?

[@myselfexplored]

I've been deploying Cisco 819 4G ISR's in the field for years - Great Kit! I do have a question, recently we have been struggling with high latency and have been exploring the external 4G antenna's to replace the two single antennas on the device. I can see from the spec of the Cisco 819 4G ISR's that they have 2x antenna connectors 'M0/MAIN' and 'M1/DIV' which appear as if they are TNC connectors and I can unscrew the stubby antennas provided. I would be using these in an indoor event space and would like to position the external antennas 15ft in the air above the device. I have found part number ANT-4G-OMNI-OUT-N - Multiband Omni-Directional Stick Outdoor 4G Antenna but noted the 'N' connector type - would this work with an N to TNC cable and if so which 4G antenna port should I connect the external antenna to? Thanks in advance!

Nice video, very helpful, like when you went over trouble shooting commands.

[@keeganpowers7712]

I'm trying to setup 4g lte on a 2921 ISR with an EHWIC-4G-LTE-V and it seems that the commands for attaching the profile to sim are missing and the profiles aren't setup. The carrier is Verizon and the sim is detected by the card.

You announced an Video about SMS Configuration - unfortunately I couldn't find any video about that. What I'm trying to do is to configure/implement a Service for my employees to send SMS through web interface from their PCs to customers (e.g. to transmit Passwords a.s.o). Do you know if such a setup impossible with the 819-4g?

[@TheTechCatalyst]

There is a way to do it... I never got back around to building it out unfortunately

[@Rahilmlk]

Please share more details of IR829 cellular configuration with remote access on private network and also how access the IOX VM available inside.

[@TheTechCatalyst]

The IOX is certainly on my list...

What type of DC Cable is recommended to use from Power Inverter to Cisco 809?

What additional config is needed to get the LAN port internet access via LTE?

[@TheTechCatalyst]

Typically just NAT the inside to the outside LTE interface.

[@viledanew]

@@TheTechCatalyst what about the opposite, as it is supposed to be a M2M router, how can we get to the LAN from "LTE" ? Thanks

[@bogdancodry]

Great video thanks for that! What the troubleshooting steps if I've got a profile already but it's showing as inactive?

[@chjmartin]

Nice job - Super helpful!

[@thebreakerofwalls9036]

10:00 troubleshooting tips are great!

[@TheTechCatalyst]

Thanks!

[@williansouzasantos876]

HI, Can you test the failover LTE function? Regards Willian

[@TheTechCatalyst]

I only have a single SIM unfortunately. I would welcome someone to sponsor a second! :-). All typical routing and NAT rules apply however so if you can get it working with a wired setup everything is similar with the 4G WAN's

[@brianmwizagondwe1321]

Configured all the configs.. The interface has received an IP and DNS IPs.. but i cant still browse. What could be the problem

[@TheTechCatalyst]

I would verify you can ping from the outside first. Once you're good there check NAT config.

[@brianmwizagondwe1321]

@@TheTechCatalyst Thanks, it has worked.

[@TheMafian87]

is it possible to use the LTE with dmvpn?

[@TheTechCatalyst]

It is!

[@TheTechCatalyst]

It is! Keep in mind the routing protocol overhead, etc will also go into your total bandwidth consumption from a billing perspective.

[@TheMafian87]

The Tech Catalyst thanks! Going to give it a try! Totally true about the data usage.

First let me thank you for taking the time to produce this video. Whilst your video was relative to an 829, I am considering to obtain a Cisco 819 and am curious about a few things. What are the major or concerning differences betwixt the 819 and 829? Is it fair to presume that an 819 or an 829 uses a standard Cisco console cable to access the IOS via the console port? Some versions of the 819 (non "W" versions) seem to have an Ethernet WAN port as well as Ethernet LAN ports, does that mean it could ostensibly function as an Ethernet to Ethernet router (absent the use of the cellular capability) to route from a DSL bridge via the WAN port to a LAN port? What makes the hardened version different from the non-hardened version? It appears that the 819 models can use an older "standard" SIM card, though if a service provdier only supports new Micro or Nano cards, can a converter of some sort work to let the newer cards function in one of these devices accepting only older standard SIM cards? Your video spoke about an AT&T profile, how difficult is it to get different profiles or to create a different profile or even determine if one needs to create a different profile for a different carrier? Say Sprint or Verizon? You had mentioned getting profiles on Cisco's website but I could not find that on their website. I want to make sure that when I purchase one it is the correct model number so that I can be sure it supports 4G as well as the proper modulation and band that would work with US mobile phone carriers. Can you provide any guidance in this area? 3rd and 4th tier carriers offer very cheap plans (such as Mint Mobile), where could I get or how could I create a profile for such a carrier? I had a question in here about IOS for an 819, though it appears my own research shows that c800-universalk9-mz.SPA.159-3.M2.bin is the latest appropriate version. Can anyone confirm? You state that these devices seem to be sold as "point to point", does that mean if I set one up and configure it all the LAN devices would be able to gain internet access via the same mobile connection (as would any router function)? Thanks for your time and consideration.

[@TheTechCatalyst]

Man it's been a while since I've done much with this stuff. The safest thing I can tell you is probably to touch base with your Cisco account team. That 829 and 819 are still out there a lot but if this is a new application I might consider the IR1101. Either way they do connect and configure like basically any other Cisco router. www.cisco.com/c/en/us/products/routers/1100-series-industrial-integrated-services-routers/index.html

881G_test(config-if)#dialer-group 1 %Remove Dialer Profile Configuration first What does it mean? can help please?

[@josecruz2574]

How far would this router typically send a signal?

[@TheTechCatalyst]

In terms of 4G it will work as well as a cell phone data plan, maybe a little better with the antennas.

[@TikiriJayathilake]

can you show us the complete config I'm having issue with getting IP address

[@TheTechCatalyst]

I just added the applicable configuration to the video description. See if that helps. Does your system list a phone number? (I forget the name of the field but I do call it out in the second half of the video.

[@robm6282]

can you do Port address translation with C819?

[@TheTechCatalyst]

I'm almost positive, yes. Normal IOS stuff more or less.

[@NAANOOZ90]

thanks for the helpful video, do have a video talk about PoE on the Switch platform, does all ir829 have PoE capability?

[@TheTechCatalyst]

Yes, there is POE on this platform. Be sure to check the data sheets for specifics.

[@lingarajubakka2727]

Nice stuff buddy 👍 👏

[@TheTechCatalyst]

Thanks 👍

[@AvidSurvivalist]

Do these have a web interface or is it strictly through the IOS CLI? I know my way around IOS, I have my CCENT, but kind of prefer a web interface since I'm planning on using this model or a similar one for my home internet. I'm looking at a 1921 with the EHWIC LTE modem or C819G, they seem to be the most affordable on ebay right now.

[@TheTechCatalyst]

I believe Cisco Configuation Professional supports at least some of this config.

[@kckoellein]

Connected your cellular antennas, eh? I see you have the LTE paddle antennas connected to 5GHz wifi antenna ports 0 and 1... :-p
