Managing a 3G/4G modem

About managing a 3G/4G modem

A 3G/4G modem connects a device to a 3G/4G network.

USB 3G/4G modems are available for the device.

A USB 3G/4G modem is hot swappable. The device uses a fixed cellular interface to manage a USB

3G/4G modem. You can enter cellular interface view to perform configurations when the device does

not have a USB 3G/4G modem installed. The configurations remain after the USB 3G/4G modem is

removed from the device.

A cellular interface can be channelized into a serial or an Eth-channel interface. The data link layer

protocols of the serial interface and Eth-channel interface are PPP and Ethernet, respectively. The

two interfaces support IP at the network layer.

The cellular interface of a 3G modem can only be channelized into a serial interface. The cellular

interface of a 4G modem can only be channelized into an Eth-channel interface.

Configuring an IP address for an Eth-channel interface of a

4G modem

About obtaining an IP address for an Eth-channel interface

An Eth-channel interface can communicate with other devices only after it obtains an IP address.

You can configure an IP address for an Eth-channel interface in the following ways:

• DHCP—The Eth-channel interface obtains the modem's IP address as its own IP address

through DHCP. The modem's IP address is automatically allocated by the service provider.

• Modem manufacturer's proprietary protocol—The Eth-channel interface obtains the

modem's IP address as its own IP address through the modem manufacturer's proprietary

protocol. The modem's IP address is automatically allocated by the service provider.

• Manual configuration.

The ways for the Eth-channel interface to obtain an IP address are mutually exclusive. The most

recent configuration overrides the previous one.

Restrictions and guidelines

Changing the IP address will result in dialup interruption. Immediate re-dialup upon interruption

might not be supported by service providers.

Procedure

1. Enter system view.

Configuring PIN verification

About PIN verification

A UIM card is used in the CDMA network and a SIM card is used in other mobile networks. Each

SIM/UIM card has a Personal Identification Number (PIN). PIN verification prevents unauthorized

access to the SIM/UIM card.

To perform PIN verification, you need to save the PIN of the SIM/UIM card on the device by using the

pin verify command and enable PIN verification. The pin verify command can be executed before

and after you enable PIN verification. After the PIN is saved on the device, the PIN is used for

verification automatically when required.

When PIN verification is enabled, PIN verification is performed after you perform any of the following

tasks:

• Install a 3G/4G modem.

• Reboot the device where a USB 3G/4G modem is attached.

• Execute the modem reboot command to reboot a 3G/4G modem.

• Hot swap a USB 3G/4G modem.

• Cold boot the device where a SIC-3G/4G modem is installed.

If PIN verification fails after a maximum number of attempts, the SIM/UIM card is locked, and a PIN

Unlocking Key (PUK) is required to unlock the card. The maximum number of attempts depends on

the 3G/4G modem model.

Procedure

1. Enter system view.

system-view

2. Enter cellular interface view.

controller cellular interface-number

3. Enable PIN verification.

pin verification enable [ pin ]

The default setting depends on the modem model.

Whether you are required to enter the PIN when enabling PIN verification depends on the

modem model.

4. Specify the PIN for verification.

pin verify { cipher | simple } string

By default, no PIN is configured on a device for 3G/4G modem verification.

This command saves the PIN on the device.

5. (Optional.) Specify a PUK to unlock the SIM/UIM card.

pin unlock puk new-pin

After the SIM/UIM card is unlocked, execute the pin verify command to save the new PIN

on the device.

6. (Optional.) Modify the PIN of the SIM/UIM card.

pin modify current-pin new-pin

The new PIN is saved in the SIM/UIM card.

After the PIN is modified, execute the

pin verify command to save the new PIN on the

device.

Configuring DM

NOTE:

Support for DM depends on the modem model.

About DM

Configuring 3G/4G modem reboot

Configuring automatic reboot

About automatic reboot

The 3G modem might malfunction in an unstable 3G network or when the application environment

changes. During a malfunction, the modem cannot respond to the device's requests or configuration

commands. If the device does not receive any responses from the 3G modem within the timeout

interval, a response failure occurs. When the number of consecutive response failures reaches the

threshold, the device restarts the 3G modem automatically.

The device does not restart the 3G modem when the 3G modem has not made a successful dialup

since the last restart. This restriction avoids repeated restarts of the 3G modem when there are

configuration errors.

Procedure

1. Enter system view.

system-view

2. Enter cellular interface view.

3. Configure the response timeout and the threshold for the number of consecutive timeouts to

enable automatic reboot of the 3G/4G modem.

modem response timer time auto-recovery threshold

By default, the response timeout is 10 seconds and the consecutive timeout threshold is 3.

The configuration is saved on the device rather than the 3G/4G modem.

Configuring manual reboot

About manual reboot

A 3G/4G modem can automatically detect running errors and reboot. If the 3G/4G modem fails to

reboot by itself, you can use this command to manually reboot it.

Procedure

1. Enter system view.

2. Enter cellular interface view.

controller cellular interface-number

3. Manually reboot the 3G/4G modem.

Binding the IMSI of the SIM card to an interface

About binding the IMSI of the SIM card to an interface

The device must support PPP LCP negotiation of the IMSI/SI when it acts as a LAC to access the

LNS in LAC-auto-initiated mode. After you bind the IMSI on the SIM card to a virtual PPP interface,

the packets sent by the device carry the IMSI.

Restrictions and guidelines

This feature is not available for distributed devices or devices operating in IRF mode.

Procedure

1. Enter system view.

system-view

2. Enter cellular interface view.

controller cellular interface-number

3. Bind the IMSI on the SIM card to an interface.

imsi bind interface-type interface-number

By default, the IMSI on the SIM card is not bound to any interface.

3G/4G modem management configuration

examples

Example: Configuring 4G modem management

Network configuration

As shown in Figure 1:

• The router provides a USB 4G or SIC-4G modem.

• The PC dials up to access an LTE network through Dial-on-Demand Routing (DDR).

For more information about DDR dialup, see "Configuring DDR."

Figure 1 Network diagram

Procedure

# Configure dialer group 1 and configure DDR to place calls for IP packets.

<Router> system-view

[Router] dialer-group 1 rule ip permit

# Channelize the cellular interface into an Eth-channel interface.

[Router] controller cellular 2/4/0

[Router-Cellular2/4/0] eth-channel 0

[Router-Cellular2/4/0] quit

# Configure an IP address for Eth-channel 2/4/0:0.

[Router] interface eth-channel 2/4/0:0

[Router-Eth-channel2/4/0:0] ip address cellular-alloc

# Enable traditional DDR on Eth-channel 2/4/0:0.

[Router-Eth-channel2/4/0:0] dialer circular enable

# Associate Eth-channel 2/4/0:0 with dialer group 1.

Troubleshooting

Symptom

A 3G/4G modem fails to function correctly. For example, the 3G/4G modem receives no signals or

fails to connect to service providers' networks.

Solution

To resolve the issue:

1. Execute the

shutdown command and the undo shutdown command on the cellular

interface.

2. If the 3G/4G modem still fails to function, execute the

modem reboot command on the cellular

interface.

3. If the issue persists, contact H3C Support.
