Parameter Description
Cellular NW Preference The cellular modem network preference setting allows you to select how
the modem should operate.
n 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).
n 3g_only: Locks the modem to operate only in 3G.
n 4g_only: Locks the modem to operate only in 4G.
n 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 switch link.
USB storage for CSR/Key Check this box if you want the USB to store CSR and private key files.
Configuring a Remote AP
A remote AP (RAP) is recommended when the network between the AP and switch is an un-trusted/non-
routable network, such as the Internet. Furthermore, a RAP supports an internal DHCP server, while a campus
AP does not.
Remote Authentication
The two most common ways to provision an AP for remote authentication are certificate-based AP
provisioning and provisioning using a pre-shared key. Although both options allow for a simple secure setup of
your remote network, you should make sure that the procedure you select is supported by your switch, the AP
model type and the end user’s client software. If you must provision your APs using a pre-shared key, you need
to know which switch models you have that do not support certificate-based provisioning.
n Certificate based authentication allows a switch to authenticate a AP using its certificates instead of a
PSK. You can manually provision an individual AP with a full set of provisioning parameters, or
simultaneously provision an entire group of APs by defining a provisioning profile which contains a smaller
set of provisioning parameters that can be applied the entire AP group. When you manually provision an
individual AP to use certificated-based authentication, you must connect that AP to the switch before you
can define its provisioning settings.
n Use Pre-Shared Key (PSK) authentication to provision an individual remote AP or a group of remote
APs using an Internet Key Exchange Pre-Shared Key (IKE PSK).
RAP Configuration
The steps to configure a remote AP using the WebUI are similar to the steps described inConfiguring an AP
using the WebUI, although some additional steps are required.
