This article describes how to configure an LTE interface on an SSR device using Mist.

1.Physical Setup

• Attach LTE antennas and insert the SIM card into the SSR130.
• Power on the device.
  
  

2. Interface Configuration (SSR Config Example)

• • LTE interfaces are configured as part of the WAN edge template. Here’s a sample configuration:
  • Ensure the following:
    • target_interface matches the LTE hardware interface.
    • apn-name is set to the correct APN for your carrier.
    • dhcp is enabled ("dhcp": "v4").
    • source-nat is enabled.
    • default-route is set to true.

Refer below Images for your reference. 

3. Validation Requirements

• • LTE interface must be DHCP-v4 enabled.
  • Source-NAT must be enabled for LTE interfaces.
  • A valid APN is required; incorrect APN will prevent the interface from coming online

4. Verification

• After configuration, verify the LTE interface is up and has obtained an IP address.
• Check connectivity (e.g., ping 8.8.8.8).
• If issues occur, confirm the APN and SIM status.

5. Troubleshooting

• If the interface does not come up, check for:
  • Incorrect APN.
  • SIM not detected.
  • No signal or carrier registration issues.

This process ensures the LTE interface on SSR130 is properly configured and operational
