cisco VZ LTE on Cisco ISR 1111 connects then disconnects

Hoping someone can help me as I having no luck getting a VZ 4G LTE connection to stay up.  Im using a Cisco 1111 -4PLTEEA

Cisco IOS XE Software, Version 16.09.03

Cisco IOS Software [Fuji], ISR Software (ARMV8EB_LINUX_IOSD-UNIVERSALK9_IAS-M), Version 16.9.3, RELEASE SOFTWARE (fc2)

 

This is the configuration I’m using,

 

access-list 1 permit any

dialer-list 1 protocol ip permit

 

controller Cellular 0/2/0

lte sim data-profile 3 attach-profile 3 slot 0

 

interface Cellular0/2/0

ip address negotiated ! only seems to support hdlc

load-interval 30

dialer in-band

dialer watch-group 1

dialer-group 1

ipv6 enable

pulse-time 1

dialer idle-timeout 0

 

ip route 0.0.0.0 0.0.0.0 Cellular0/2/0 254

 

 

The config above gets me an ip from VZ and bounds it to the cell0/2/0 interface as the dialer works and brings up the connection etc.

I can pass traffic in and out but the connection goes down at about 4:30/5 min of being up. This happens while I have constant traffic to and from the Cisco 1111.

I can’t understand why cell0/2/0 goes down. I have tried different IOS’ but that didn’t seem to help.

 

Ce0/2/0 - dialer type = DIALER CWAN

Idle timer (120 secs), Fast idle timer (20 secs)

Wait for carrier (30 secs), Re-enable (15 secs)

Dialer state is enabling

Time until interface enabled 14 secs

 

Dial String      Successes   Failures    Last DNIS   Last status

lte                      1          0    00:04:50       successful   Default

BCM-Plymouth-ISR1K-GW#

I seem to be attached to the correct profile

 

 

Profile 3, Packet Session Status = ACTIVE

        Cellular0/2/0:

        Data Packets Transmitted = 5 ,  Received = 80

        Data Transmitted = 296 bytes, Received = 4640 bytes

        IP address = 166.252.xx.xx

        Primary DNS address = 198.224.188.236

        Secondary DNS address = 198.224.189.236

        Primary DNS address = 198.224.188.236

        Secondary DNS address = 198.224.189.236

 

 

Also verify the APN type, it looks like I’m using the correct APN which is profile 3

 

PDP Type = IPv4v6

Access Point Name (APN) = ne01.VZWSTATIC

Authentication = None

 

 

Signal on this LTE device is perfect

 

LTE Bandwidth = 20 MHz

Current RSRQ = -13 dB

Current SNR = 0.7  dB

Radio Access Technology(RAT) Preference = AUTO

Radio Access Technology(RAT) Selected = LTE

 

 

Im at a real loss as to why the LTE connection bounces especially when it initially connects with no issues and has a strong RSSI.

There isn’t many examples of LTE configuration for an ISR 1100 and the commands/config are different than the 1800 series.

One thing I notice is that somehow if I reboot the router with the sim in 0/2/1 instead of 0/2/0 the want ip is pingable but not bound to any cell interface.

Not sure at this point if my config is not right or it’s a VZ issue!!?

 

 

If anyone has experience with this and can help me I would appreciate it.

 

Thanks, Paul
