Cellular uplinks have a lower priority than wired links by default. You can change the default by changing the
profile-specific priority or by changing the default cell priority.
(host) (config) #cellular priority <prior>
5. Check the modem dialing status. The connection may take up to a 45 seconds to establish. To see the
connection progress, execute the show uplink connection uplink id command.
6. Verify the connection is established and IP addressed is programmed.
l Once the cellular link state is Connected, you can find the PPP dynamic entries by executing the show
uplink connection id command
l The IP address can be found using the show ip interface brief command
l The Gateway can be found using the show ip route command
l The DNS entries can be found using the show ip domain-name command
Configuring a New USB Modem
Cellular modems must be activated before they can communicate on the cellular network. Typically, the
activation is done by the carrier. Some carriers use a proprietary PC client. In all cases, ensure that your modem
works on your PC before using it on the W-600 Series controller.
Verify your modem is activated and works with your Microsoft Windows or Apple Mac computers.
Each time a USB device is inserted, Linux assigns it a new USB address. This is true even if the same device is re-
inserted. Modem ports are organized under their individual addresses. For example, ttyUSB0 at address 3 is
separate than ttyUSB0 at address 7. The address is displayed when you execute the commands, show usb
and show usb verbose (the Dev# field).
Configuring the Profile and Modem Driver
1. Insert the USB Modem into an open USB port.
2. Verify that the modem is detected using the show usb command.
3. If your modem is not recognized (such as “type is unknown”, “no matching profile”, or “device not ready”),
use the show usb verbose command to verify your modem is listed.
4. From the command-line interface, issue the cellular profile <profile> command to create a cellular profile
and import the identifiers.The Dialer, TTY, and Driver fields are the new profile defaults.
5. Configure the modem driver.
The default option driver is a catch-all for cellular modems. Nearly all cards use this driver and support for
new modems are added here. Once option driver is configured to work with this device, it recognizes the
modem and exposes its ports.
If you get entries similar to the example below, it means the driver does not work with these ports. Try the
other drivers and see if they pick up the device. Airprime is the reliable catch-all driver, Sierra is for certain
Sierra cards, and cdc-acm is a legacy abstract control modem driver. Your goal is to assign a driver for the
unclaimed (none) interfaces (If#).
(host) #show usb verbose
...
I: If#= 0 Alt=0 # EPs= 3 Cls=ff (vend.) Sub=ff Prot=ff Driver=(none)
I: If#= 1 Alt=0 # EPs= 2 Cls=ff (vend.) Sub=ff Prot=ff Driver=(none)
If no option driver appears or only storage interfaces appear, then the modem must be switched to data
mode. For more information, see
