Introduction

This document describes the initial configuration and installation process for the Cellular Gateway 522-E.

Background Information

Any complex configuration procedure is beyond the scope of this publication. The CG522-E is a Plug and Play device, but the information provided allows ease of use. Here is a hyperlink for all the published CG522-E documentation.

Prerequisites

Requirements

Cisco recommends that you have basic knowledge of these topics:

• 5G Cellular Network Basics
• Cisco IOS® XE and Cisco IOS® CG

Components Used

CG522-E (v.17.04.01a)

CG522-E Modem EM9190 (v.SWIX55C_01.07.13.00)

WS-C3850-12X48U (v.03.07.04E)

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

General Information of the CG522-E

The CG522 works as an NSA (Non-standalone) device. This means the 5G band is on the data plane and LTE on the control plane. As a result, traffic needs to be pushed in and out of the CG522 for the NSA device to aggregate from 4G bands to 5G bands.

Installation of the SIM card(s)

Beside the ethernet port, the CG522-E has a cover for the SIM slots. The cover is held together by a Philips head screw. Carefully remove the screw to reveal the SIM slots.

The SIM size is only compatible with MICRO SIM (Height: 15 mm, Width: 12 mm, Thickness: 0.76mm).

Note: Use a MICRO SIM card adapter for NANO SIM cards.

Installation of the indoor 5G Antenna

Occasionally, there is a need to install a 5G Antenna onto the CG522-E. The only supported indoor 5G Antenna is the 5G-ANTM-SMA-D (Multi-Band Swivel Mount Dipole antenna) (SMA). To insert the antenna, ensure there is no power to the CG522-E, take the SMA male connector end of the antenna, and twist the connector into the female connector on the CG522-E until moderately tight.

Note: The 5G-ANTM-SMA-D is intended for indoor use. The antenna is designed to connect to a dedicated antenna port on the device. No special tools are required to install the antenna.

Warning: Please utilize the 5G-ANTM-SMA-D installation guide for safety precautions and protocols to operate with lightning activity.

Power up the CG522-E

The CG522-E can be powered on from multiple methods, which include PoE+ and a 12V 2.5A power brick 4-pin connector.

To confirm the CG522-E is PoE compatible, look for the lightning symbol on the ethernet port.

Note: The PoE+ cable must be no longer than 100 m. If a non-PoE CG522-E unit is replaced, the same one is received.

Tip: This is the hardware installation at the most basic level. For more information, utilize this hardware installation guide.

Software Installation Procedure:

Access the CG522-E via Console

The CG522-E can be accessed by console session. Parameters are:

• baud rate: 115200 bits/sec
• 8 data bits
• no parity
• 1 stop bit (8N1)
• no flow control necessary
• username: admin
• password: device serial number

Locate the device serial number by looking at the bottom of the unit. It also shows up within the bootup sequence. This message appears:

Device is using default day0 password: xxxxxxxxxxx 

Access the CG522-E via SSH

The CG522-E can be accessed by SSH via a Layer 2 Interface from a switch/router. Ensure that the interface is assigned an IP address within the 192.168.1.x subnet, as the CG522-E default interface IP address is set to 192.168.1.1.

On the uplink device (Switch/Router), configure these commands:

Switch# configure terminal
Switch(config)# interface <interface>
Switch(config-if)# no switchport
Switch(config-if)# ip address 192.168.1.2 255.255.255.0
Switch(config-if)# exit 

Switch(config)# exit
Switch# ssh -l admin 192.168.1.1
Password: 

On the CG522-E, intial parameters are:

• IP address: 192.168.1.1
• username: admin
• password: device serial number

Locate the device serial number by looking at the bottom of the unit. It also show up within the bootup sequence. This message appears on the console:

Device is using default day0 password: xxxxxxxxxxx 

Tip: You can SSH into an SVI of a switch then SSH into the CG522-E with this method, however an SVI is not enough to switch the CG522 and uplink device. You must include the L2 Interface within the uplink interface of the CG522-E.

Change the Password

Once there is console or SSH access, change the username and password of the CG522-E with these commands.

CellularGateway# configure terminal
CellularGateway(config)# aaa authentication users user admin change-password old-password

After implementing these commands, observe the prompts:

Value for 'old-password' (<string>): *********
Value for 'new-password' (<string>): ********
Value for 'confirm-password' (<string>): ********

5G CC information is an indication of the use of 5G. The selected band currently shows the utilization of LTE, but as an NSA device, the LTE band is selected due to no traffic in this particular simulation.

Check and Configure Cellular Access Point Name (APN)

The CG522-E usually is able to configure the APN automatically based off its SIM. This procedure is how to confirm an active APN profile. Sometimes, there is need to configure a static APN profile.

CellularGateway# show cellular 1 profile
PROFILE ID   APN        PDP TYPE   STATE     AUTHENTICATION  USERNAME  PASSWORD  
---------------------------------------------------------------------------------
1            Broadband  IPv4       ACTIVE      none            -         -         
2            ims        IPv4v6     INACTIVE    none            -         -         

How to configure a custom APN:

CellularGateway# configure terminal
CellularGateway(config)# controller cellular 1​
CellularGateway(config-cellular-1)# sim slot <# of sim slot in use>​
CellularGateway(config-slot-0)# profile id <#> apn <APN name> pdn-type IPv4v6 authentication <authentication type> username <username> password <password>
CellularGateway(config-slot-0)# attach profile <#>
CellularGateway(config-slot-0)# commit

Tip: Some APNs do not require authentication; which means there is no need to define any authentication if not needed. EX: profile id <#> apn pdn-type IPv4v6 <-- this is a valid command.

How to remove an APN profile:

CellularGateway# config term
Entering configuration mode terminal
CellularGateway(config)# controller cellular 1
CellularGateway(config-cellular-1)# sim slot 1     
CellularGateway(config-slot-1)# no attach-profile 1
CellularGateway(config-slot-1)# no profile id 1 apn broadband
CellularGateway(config-slot-1)# commit

Note: No authentication is required for LTE.

Note: Verizon requires at least 2 profiles; an attach profile (usually vzwims or ims) and a data/default profile. AT&T only requires one profile as needed for data/default and attach profiles (broadband).

Configure Primary SIM slot and SIM failover commands

Run these commands to define the primary SIM slot and to utilize the SIM failover timer function. A manual failover would be to define the primary SIM slot again.

CellularGateway# config term
Entering configuration mode terminal
CellularGateway(config)# controller cellular 1
CellularGateway(config-cellular-1)# sim primary-slot <0/1> 
CellularGateway(config-cellular-1)# commit
Commit complete.
CellularGateway(config-cellular-1)# end

CellularGateway# config term
Entering configuration mode terminal
CellularGateway(config)# controller cellular 1
CellularGateway(config-cellular-1)# sim max-retry 5
CellularGateway(config-cellular-1)# sim failovertimer 7
CellularGateway(config-cellular-1)# commit
Commit complete.
CellularGateway(config-cellular-1)# end
CellularGateway#
