I am configuring a 2901 ISR with an EHWIC 4G LTE Verizon module for the first time. I've followed the configuration instructions but I'm having trouble with the interface changing state to down every 30 seconds or so. The dialer idle-timout is set to defaults. I'm also using a Verizon private IP address allocated in an IP pool for our enterprise environment. Any help would be greatly appreciated.
See attached configuration output below:
