Before configuring the cellular MDA and cellular ports, the following prerequisites must be considered.
Depending on the radio module selected, 4G LTE/3G network coverage is required where the node is to be physically installed.
The operator must subscribe to a service plan with a wireless service provider. For private cellular networks, the operator must procure a SIM that allows the node to connect to the private cellular network being deployed. If dual SIM functionality is required, the operator must subscribe to a second service plan with another wireless provider and procure a second SIM.
The radio firmware shipped with the node is a generic firmware version. Some service providers require a specific radio firmware version to run on the node, depending on the radio variant used on the node and the wireless service provider being connected to; in this case, the firmware on the node must be updated to the correct version. See the 7705 SAR-Hm and SAR-Hmc Software Release Notes for details about updating the radio firmware to the correct version. If dual SIM functionality is enabled, the firmware associated with the second wireless service provider must be updated for the associated SIM.
The SIM or SIMs must be physically installed before powering up the router and configuring the cellular MDA and cellular ports.
For a typical GSM profile, and if required by the service plan, the following information must be obtained from the service provider: Access Point Name (APN), username, and password. For dual SIM deployments, obtain the GSM profile information for each SIM.
When the prerequisites have been met, the following configurations are required.
A cellular port interface must be configured for each installed SIM.
The required SIMs must be configured under the cellular MDA.
The following CLI syntax shows an example of the required cellular MDA and cellular port parameters:
*A:Dut# configure card 1 mda 1 cellular sim 1
*A:Dut>config>card>mda>cellular>sim# pin
Enter PIN: xxxx
Re-enter PIN: xxxx
*A:Dut>config>>card>mda>cellular>sim# exit
*A:Dut# configure port 1/1/1 cellular pdn
*A:Dut>config>port>cellular>pdn# pdn-profile 1
*A:Dut>config>port>cellular>pdn# exit
*A:Dut#
A cellular system PDN profile must be created and the corresponding APN, GSM parameters (such as username, password, and authentication), and protocol must be configured for each installed SIM. For an example of the CLI syntax required for the PDN profile configuration, see PDN profile.
A PDN router interface must be created for each cellular port to enable services over the cellular port; for information, see the 7705 SAR-Hm and SAR-Hmc Main Configuration Guide, "PDN router interfaces".
