Parameter Description
Dial String The dial string for the USB modem. This parameter only needs to be
specified if the default string is incorrect.
PPP Username Enter the PPP username provided by the cellular service provider.
PPP Password Enter the optional PPP password provided by the cellular service
provider.
Confirm PPP Password Re-enter the optional PPP password provided by the cellular service
provider.
Modeswitch USB cellular devices on remote APs typically register as modems, but
may occasionally register as a mass-storage device. If a remote AP
cannot recognize its USB cellular modem, use setting to specify the
parameters for the hardware model of the USB cellular data-card.
NOTE: You must enclose the entire modeswitch parameter string in
quotation marks. Example follows:
"-v <default_vendor> -p <default_product> -V <target_vendor> -P
<target_product> -M <message_content>"
Cellular NW Preference The cellular modem network preference setting allows you to select how
the modem should operate.
l auto (default): In this mode, the modem firmware will control the
cellular network service selection; so the cellular network service
failover and fallback is not interrupted by the remote AP (RAP).
l 3g_only: Locks the modem to operate only in 3G.
l 4g_only: Locks the modem to operate only in 4G.
l advanced: The RAP controls the cellular network service selection
based on the Received Signal Strength Indication (RSSI) threshold-
based approach. Initially the modem is set to the default auto mode.
This allows the modem firmware to select the available network. The
RAP determines the RSSI value for the available network type (for
example 4G), checks whether the RSSI is within required range, and if
so, connects to that network. If the RSSI for the modem’s selected
network is not within the required range, the RAP will then check the
RSSI limit of an alternate network (for example, 3G), and reconnect to
that alternate network. The RAP will repeat the above steps each time
it tries to connect using a 4G multi-mode modem in this mode.
Link Priority Ethernet Set the priority of the wired uplink. Each uplink type has an associated
priority; wired ports having the highest priority by default.
Link Priority Cellular Set the priority of the cellular uplink. By default, the cellular uplink is a
lower priority than the wired uplink; making the wired link the primary
link and the cellular link the secondary or backup link.
Configuring the cellular link with a higher priority than your wired link
priority will set your cellular link as the primary controller link.
USB storage for CSR/Key Check this box if you want the USB to store CSR and private key files.
