Need your help. Our company made a decision to implement a network backup that uses Verizon LTE 4G. The setup is as follows: On the corporate side there is a Cisco 2911 using VPN going to the Verizon private network. On the remote side we have a series of layer 3 switches (Cisco 3560s). On the suggestion of Verizon we purchased CradlePoint CBA750 modem/router devices.
We need to use the Verizon connection as the backup. The primary is Metro Ethernet going through another ISP. When connecting the CradlePoint to the switch the link will not activate (actually receive a down/ err-disable). I can use a PC directly to the CradlePoint Ethernet port and test successfully.
My question is does anyone have experience in connecting the CradlePoint to Cisco Switches? I have eliminated the cable (it is straight-through) and also made a call to both Verizon and CradlePoint (have not called Cisco as of this writing) The CradlePoint is being set in IP Pass-through mode and is receiving its address from Verizon. I think I have covered the basics so if anyone could lead me in the right direction I would appreciate it. Thanks.
