Interfaces
Note If manual is configured forthe carrier selection mode and a specific network
technology is selected for the cellular network technology, your modem must support the
selected technology or no cellular connection will be established. If you are using a cellular
connection to perform this procedure, you may lose your connection and the device will
no longer be accessible.
11. SIM failover is enabled by default, which means that the modem will automatically fail over
from the active SIM to the next available SIM when the active SIM fails to connect. To disable:
(config network interface my_wwan)> modem sim_failover false
(config network interface my_wwan)>
If enabled:
a. Set the number of times that the device should attempt to connect to the active SIM
before failing over to the next available SIM:
(config network interface my_wwan)> modem sim_failover_retries num
(config network interface my_wwan)>
The default setting is 5.
b. Configure how SIM failover will function if automatic SIM switching is unavailable:
(config network interface my_wwan)> modem sim_failover_alt value
(config network interface my_wwan)>
where value is one of:
n
n
n
12. The IX10 device uses a preconfigured list of Access Point Names (APNs) when attempting to
connect to a cellular carrier for the first time. After the device has successfully connected, it
will remember the correct APN. As a result, it is generally not necessary to configure APNs. See
Configure cellular modem APNs
13. (Optional) To configure the IP address of a custom gateway or a custom netmask:
a. Enable the custom gateway:
(config network interface my_wwan)> modem custom_gw enable true
(config network interface my_wwan)>
b. Set the IP address and netmask of the custom gateway:
(config network interface my_wwan)> modem custom_gw gateway ip_
address/netmask
(config network interface my_wwan)> modem custom_gw
To override only the gateway netmask, but not the gateway IP address, use all zeros for
the IP address. For example, 0.0.0.0./32 will use the network-provided gateway, but with a
/32 netmask.
