Interfaces
(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 TX54 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.
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 metric:
(config network interface my_wwan)> ipv4 metric num
(config network interface my_wwan)>
See Configure WAN/WWAN priority and default route metrics
metrics.
c. Set the relative weight for default routes associated with this interface. For multiple active
interfaces with the same metric, the weight is used to load balance traffic to the interfaces.
