Usage Guidelines

Usage Scenario

An access point name (APN) identifies an external PDN network (for example, the Internet or IMS network) that users want to access.

You can run the apn command to configure an APN in the APN profile.

Precautions

  • APNs are provided by the carrier.
  • After an APN is configured, it is permanently recorded in a 3G or LTE modem. If the APN changes, reconfigure it.
  • If the apn command is run repeatedly in the same APN profile view, the latest configuration overwrites the earlier ones.

Example

# Configure an APN named 3gnet in the APN profile.

Views

Cellular interface view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

Generally, the IP layer limits the size of a packet sent each time. Any time the IP layer receives an IP packet, it checks to which local interface the packet needs to be sent and obtains the MTU of the interface. Then, the IP layer compares the MTU with the packet size. If the packet size is larger than the MTU, the IP layer disassembles the packet to fragments smaller than the MTU.

If forcible unfragmentation is configured, oversized packets are discarded at the IP layer. To prevent packet loss on the network, large packets must be forcibly fragmented. Run the mtu command to set the size of a fragment.

Precautions

If you run the mtu command multiple times in the same cellular interface view, only the latest configuration takes effect.

Follow-up Procedure

Run the shutdown and undo shutdown/restart commands to restart the related physical interface to make the configuration take effect.

Example

# Set the MTU of cellular interface 0/0/0 to 1200 bytes.

Usage Guidelines

Usage Scenario

Usually, signal quality does not affect 3G/LTE link establishment by a 3G/LTE modem in dialup mode. You can use the rssi-threshold command to configure signal quality to affect establishment and disconnection of 3G/LTE links. When the RSSI is less than or equal to the threshold, the 3G/LTE modem cannot establish 3G/LTE link in dialup mode, and the established 3G/LTE links will be disconnected.

  • When services have high 3G/LTE link quality requirements and will be greatly affected by poor link quality, set a large RSSI threshold to detect link quality and take measures in a timely manner.
  • When services have low 3G/LTE link quality requirements and will be slightly affected by poor link quality, set a small RSSI threshold to prevent establishment failures and disconnection of 3G/LTE links.

Precautions

  • When you run the rssi-threshold rssi-threshold command multiple times on a cellular interface, only the latest configuration takes effect.

Views

APN profile view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

To improve data transmission reliability of the 3G or LTE link, you can use two 3G cellular interfaces One cellular interface functions as the master link to connect to a 3G or LTE network, the other cellular interface functions as the backup link to connect to another 3G or LTE network. When the master 3G or LTE link is faulty, traffic is automatically switched to the backup 3G or LTE link, improving reliability of access to the Internet.

However, some devices do not support two cellular interfaces or the costs of two cellular interfaces are high for users. Users can use a cellular interface supporting dual SIM cards. One SIM card functions as the master SIM card, the other SIM card functions as the backup SIM card. The master and backup SIM cards connect to different 3G or LTE networks. If dial-up fails because the account balance of the master SIM card is insufficient, the master SIM card is faulty, the 3G or LTE link signal quality is poor, or the connected 3G or LTE network is faulty, traffic is automatically switched to the backup SIM card, ensuring uninterrupted enterprise services.

You can run the sim-id command on an APN profile to set the ID of a SIM card to determine the master or backup SIM card to be bound to the APN profile.

  • When the APN profile is bound to the master SIM card, the cellular interface can connect to the 3G or LTE network through the master SIM card.
  • When the APN profile is bound to the backup SIM card, the cellular interface can connect to the 3G or LTE network through the backup SIM card.
  • When the cellular interface are bound both to the APN profiles, the master SIM card is preferentially used to connect to the 3G or LTE network. Only if dial-up fails because the account balance of the master SIM card is insufficient, the master SIM card is faulty, the 3G or LTE link signal quality is poor, or the connected 3G or LTE network is faulty, traffic is automatically switched to the backup SIM card.

Precautions

If you run the sim-id command in the same APN profile view multiple times, only the latest configuration takes effect.

The master and backup SIM cards cannot simultaneously work. Upon a SIM card switchover, traffic is interrupted for a short period.

Example

# Set the ID of the SIM card bound to the APN profile ltenet to 2, indicating that ltenet is bound to the backup SIM card.

Parameters

Parameter

Description

Value

rssi-threshold

Specifies the RSSI threshold for switching between SIM cards.

When the received signal strength is lower than the RSSI threshold, the cellular interface automatically switches between SIM cards. For example, if the RSSI threshold is -105 dBm, the SIM cards are switched when the received signal strength is lower than -105 dBm.

The value is an integer that ranges from -120 to -60, in dBm.

The recommended RSSI threshold is -105 dBm.

Views

Cellular interface view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

When two SIM cards are available, if the 3G or LTE link signal quality on one SIM card is poor and affects data transmission, the other SIM card needs to provide 3G or LTE services in time.

The RSSI indicates the strength of signals received on a cellular interface. You can run the sim switch rssi-threshold command to configure automatic switchover between SIM cards based on the RSSI threshold. When the received signal strength is lower than the RSSI threshold, the cellular interface automatically switches between SIM cards.

Precautions

Set a proper RSSI threshold based on the 3G or LTE link signal quality.

  • A large RSSI threshold (such as -70 dBm) results in frequent switchovers between SIM cards. Traffic is frequently interrupted.
  • A small RSSI threshold (such as -110 dBm) results in no switchover between SIM cards even if the 3G or LTE link signal quality is poor. The SIM card providing poor-quality 3G or LTE services is always in use.

If you run the sim switch rssi-threshold rssi-threshold command in the same cellular interface view multiple times, only the latest configuration takes effect.

The SMS service with a specified ID has been configured using the sms item command.

Precautions

Currently, the SMS alarm function can be configured on interfaces only when cellular, ATM, and serial interfaces are used as the active and standby interfaces.

This command can be run on each interface at most four times, and the latest configuration does not override the previous ones.

Example

# Configure the SMS alarm function on Cellular0/0/0 to send the short message "The interface is in Up state." to the phone number +8613812345678 when the link on the interface goes Up. Send the short message "The interface is still in Up state." to the phone number if services are not switched back to the active link after 120 minutes.
