Remote Authentication Dial-in User Service (RADIUS)
The PMP configuration of 450 Platform Family includes support for RADIUS (Remote Authentication
Dial In User Service) protocol functionality including:
•
SM Authentication: Allows only known SMs onto the network (blocking “rogue” SMs), and can be
configured to ensure SMs are connecting to a known network (preventing SMs from connecting to
“rogue” APs). RADIUS authentication is used for SMs, but not used for APs.
•
SM Configuration: Configures authenticated SMs with MIR (Maximum Information Rate), High
Priority, and VLAN (Virtual LAN) parameters from the RADIUS server when a SM registers to an AP.
•
User Authentication allows users to configure a separate User authentication server along
with the SM authentication server. If firmware is upgraded while using this functionality and no
User authentication servers are configured, then AP continues to use the SM authentication server
for User authentication
•
SM Accounting provides support for RADIUS accounting messages for usage-based billing. This
accounting includes indications for subscriber session establishment, subscriber session
disconnection, and bandwidth usage per session for each SM that connects to the AP.
•
Centralized AP and SM user name and password management: Allows AP and SM usernames and
access levels (Administrator, Installer, Technician and Read-Only) to be centrally administered in the
RADIUS server instead of on each radio and tracks access events (logon/logoff) for each username
on the RADIUS server. This accounting does not track and report specific configuration actions
performed on radios or pull statistics such as bit counts from the radios. Such functions require an
Element Management System (EMS) such as Cambium Wireless Manager. This accounting is not the
ability to perform accounting functions on the subscriber/end user/customer account.
•
Framed-IP-Address: Operators may use a RADIUS server to assign management IP addressing to
SM modules. SNMP
The management agent supports fault and performance management by means of an SNMP interface.
The management agent is compatible with SNMP v2c and SNMP v3 using Management Information Base
(MIB) files which are available for download from the Cambium Networks Support website:

Network Time Protocol (NTP)
The clock supplies accurate date and time information to the system. It can be set to run with or without
a connection to a network time server (NTP). It can be configured to display local time by setting the
time zone and daylight saving in the Time web page.
If an NTP server connection is available, the clock can be set to synchronize with the server time at
regular intervals. The 450 Platform Family radios may receive NTP data from a CMM4 module or an NTP
server configured in the system’s management network.
