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
none: The device will perform no alternative action if automatic SIM switching is
unavailable.
n
reset: The device will reset the modem if automatic SIM switching is unavailable.
n
reboot: The device will reboot if automatic SIM switching is unavailable.
12. The IX14 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 for further information and instructions for setting an APN.
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.
14. Optional IPv4 configuration items:
a. IPv4 support is enabled by default. To disable:
(config network interface my_wwan)> ipv4 enable false
(config network interface my_wwan)>
b. Set the MTU:
(config network interface my_wwan)> ipv4 mtu num
(config network interface my_wwan)>
