•
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.
•
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. PMP/PTP 450 platform devices may receive NTP data from a CMM4 module or an NTP server configured
in the system’s management network.
The Time Zone option is configurable on the AP’s/BHM’s Time Configuration page, and may be used to offset the
received NTP time to match the operator’s local time zone. When set on the AP/BHM, the offset is set for the
entire sector (AP/BHSs is notified of the current Time Zone upon initial registration). If a Time Zone change is
applied, the AP/BHSs are notified of the change in a best effort fashion, meaning some AP/BHSs may not pick up
the change until the next reregistration. Time Zone changes are noted in the Event Log.
An AP/BHM which is receiving NTP date and time information from an NTP server or from a GPS synchronization
source may be used as an NTP server. Any client which has IP connectivity to the
BHM may request NTP date and time information from the AP/BHM. No additional configuration
(other than the AP/BHM receiving valid NTP data) is required to use the AP/BHM as an NTP server.
