(config network interface my_wwan)> modem sim_failover_retries num
(config network interface my_wwan)>
The default setting is 5.
b. Configure how SIMfailover will function if automatic SIMswitching 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 alternativeaction if automatic SIMswitching is
unavailable.
n
reset: The device will reset the modem if automatic SIMswitching is unavailable.
n
reboot: The device will reboot if automatic SIMswitching is unavailable.
12. The IX20 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. Asa result, it is generally not necessary to configure APNs. See
Configure cellular modem APNsfor further information and instructionsfor setting an APN.
13. (Optional) To configure the IPaddressof 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 IPaddress 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 IPaddress, use all zerosfor
the IPaddress. For example, 0.0.0.0./32 will use the network-provided gateway, but with a
/32 netmask.
14. Optional IPv4 configuration items:
a. IPv4support is enabled by default. To disable:
(config network interface my_wwan)> ipv4 enable false
(config network interface my_wwan)>
b. Set the type, which determines how the modem in the device obtainsan IPaddressfrom
the cellular network.
(config network interface my_wwan)> ipv4 modem_type value
(config network interface my_wwan)>
Where value is one of:
n
static: Digi device obtainsthe static IPaddress from the cellular network.
n
dhcp: Digi device obtainsIPaddressvia a DHCPserver on the cellular network.
