The wirelessmodem interface provides access (through a wireless modem/wwan) to wireless networks provided by various cellular providers. VyOS uses the interfaces wirelessmodem subsystem for configuration.
Common interface configuration¶
Set a human readable, descriptive alias for this connection. Alias is used by
show interfaces command or SNMP based monitoring tools.
set interfaces wirelessmodem wlm0 description 'This is an awesome interface running on VyOS'
Disable given <interface>. It will be placed in administratively down
set interfaces wirelessmodem wlm0 disable
Place interface in given VRF instance.
There is an entire chapter about how to configure a VRF, please check this for additional information.
set interfaces wirelessmodem wlm0 vrf red
WirelessModem (WWAN) options¶
When set the interface is enabled for “dial-on-demand”.
Use this command to instruct the system to establish a PPP connection automatically once traffic passes through the interface. A disabled on-demand connection is established at boot time and remains up. If the link fails for any reason, the link is brought back up immediately.
Retrive interface information from given WWAN interface.
